Description

Microstructure manufacturing apparatus and microstructure manufacturing method

The present invention relates to a microstructure manufacturing apparatus and a microstructure manufacturing method using the microstructure manufacturing apparatus. The microstructure manufacturing apparatus is used for manufacturing microstructures including microscopic components such as micro LEDs and microchips. Micro-molded objects formed by micro-processing techniques such as rice imprinting, micro-structures composed of micro-insulation sheets including glass chips, etc. Specifically, it relates to a microstructure manufacturing apparatus and a microstructure for joining, additionally pressing, or separating (peeling) the joined microstructures, or transferring the microstructures to be separated. Manufacturing method.

Conventionally, as such a microstructure manufacturing apparatus, there is a mold release device including a peeling prevention mechanism that pressurizes at least one of a film-shaped mold and a to-be-molded object so as not to peel off until a predetermined peeling position is reached; A holding part that holds either the mold or the object to be molded; a tension imparting mechanism that imparts tension to the mold or the object to be molded; and a moving mechanism that relatively moves the peeling prevention mechanism to the mold and the object to be molded (for example, refer to Patent Document 1). Using the nanoimprint technology, the molding pattern of the mold is pressed to a molded object such as resin, and the molding pattern is transferred to the molding object by using heat and light, and then the mold is separated from the molding object. The example shown in Patent Document 1 includes an angle adjustment mechanism that peels off a flexible film-shaped mold from a peeling position with respect to a molded object held by a holding portion, and separates the peeled mold with The angle between the formed objects is adjusted to a certain angle. That is, by means of the angle adjustment mechanism, the molding pattern of the mold is pulled out obliquely from the object to be molded at a certain demolding angle.

[Problems to be Solved by Invention]

However, in Patent Document 1, since the molding pattern of the mold is drawn out at a predetermined angle obliquely with respect to the uneven pattern transferred to the object to be molded, the uneven pattern of the object to be molded is deformed in shape during the peeling process, resulting in damage. Specifically, the case of the nanoimprint shown in FIGS. 15( a ) to 15 ( c ) will be described. In the state before peeling as shown in FIG. 15( a ), the uneven pattern 210 transferred to the object 200 is perpendicular to the bottom surface 220 of the object 200 by bonding with the uneven pattern 110 of the mold 100 . stand up. However, in the state of peeling shown in FIG. 15( b ), as the molding pattern 110 of the mold 100 is pulled out obliquely, the convex portion 211 of the concavo-convex pattern 210 of the object 200 collapses. Therefore, in the state after peeling as shown in FIG. 15( c ), the convex portion 211 of the concave-convex pattern 210 once collapsed maintains the collapsed state and does not return to the state before the peeling. In this way, when the direction in which the molding pattern 110 of the mold 100 is extracted from the uneven pattern 210 of the object 200 (the peeling direction) is oblique, the longer the unevenness difference of the uneven pattern 210 is, the more likely it is to deform (collapse) in shape, and there is a possibility that The problem of realizing high-precision imprint molding. In particular, in the case of nanoimprinting, since the concavo-convex pattern is extremely fine, even a slight shape deformation (collapse) at the time of peeling can cause damage to the concave-convex pattern, and there is a problem that a highly accurate concave-convex pattern cannot be produced. However, not only micro-molded objects formed by nanoimprint technology, but also micro-structures including micro-LEDs, micro-chips and other micro-elements, micro-structures composed of micro-insulation sheets including glass chips, etc. are not only small in size and Easily damaged and therefore not easy to handle. Therefore, in addition to the separation device including the mold release device as in Patent Document 1, a joining device for the separated minute structures, an additional pressing device, a transfer device for the minute structures, and the like are required. In such a case, a manufacturing apparatus that performs joining, additional pressing, separation, transfer, etc. of minute structures with the same structure is expected.

In order to detect the position of the 1st non-opposing surface Br etc. of the 1st plate-shaped member B, it is preferable to arrange|position the clearance gap detection sensor (not shown) in the 1st indoor surface 10a. The second indoor surface 10b is formed on the plane in the XY direction on the second plate-shaped member C to directly or indirectly face the second non-opposing surface Cr of the back surface in the Z direction. The chamber 10 has an inlet/outlet 10c for allowing the first plate-shaped member B and the second plate-shaped member C to enter and exit the transformer chamber 1 that can be sealed. The inlet and outlet 10c of the chamber 10 are configured to be freely openable and closable, and are opened and closed by a drive mechanism 10d composed of an actuator or the like. In addition, the transformer chamber 1 of the chamber 10 has a separate type, a partially open-close type, and the like, and the structure of the inlet and outlet 10c is different from each other. The loading of the first plate-shaped member B and the second plate-shaped member C into the transformer chamber 1 is performed sequentially or simultaneously by, for example, a conveying mechanism (not shown) such as a conveying robot. The unloading of the first plate-shaped member B and the second plate-shaped member C from the transformer chamber 1 is performed simultaneously or sequentially by the conveying mechanism.

The fluctuating portion 2 is in contact with the first non-opposing surface Br of the first plate-shaped member B carried in in the thickness direction (Z direction), and is arranged so as to be separated from the first inner surface 10 a of the chamber 10 . The variable part 2 has the displacement part 2a which contacts the 1st non-opposing surface Br of the 1st plate-shaped member B carried in along the thickness direction (Z direction) with respect to the 1st inner surface 10a of the chamber 10. The displacement portion 2a is configured to be deformable or movable in the thickness direction (Z direction), and is prevented from being in contact with the thickness direction ( The Z direction) intersects the direction (XY direction) so as to be positioned and integrated. That is, the variable portion 2 is configured such that the displacement portion 2a is arranged to be deformable or movable in the Z direction with respect to the first inner surface 10a of the chamber 10, and the first displacement portion 2a is deformed or moved along with the displacement portion 2a. The plate-like member B moves in the Z direction. Between the variable portion 2 and the first inner surface 10 a of the chamber 10 , a first space portion 4 is formed apart from the transformation chamber 1 . The first space portion 4 is formed in an airtight shape by bringing the first non-opposing surface Br of the first plate-shaped member B into contact with the displacement portion 2 a of the variable portion 2 . Furthermore, it is preferable that the variable part 2 has the 1st ventilation opening 2b which makes the 1st non-opposing surface Br of the 1st plate-shaped member B and the 1st space part 4 communicate.

1 to 6 etc. as a specific example, the variable portion 2 is constituted by an elastic ventilator 21 attached to the first interior surface 10a of the chamber 10 so as to be elastically deformable in the Z direction. For example, the elastic ventilation body 21 of the illustrated example is formed of an annular member such as a gasket or an O-ring, and the annular member is formed of an elastically deformable material such as soft synthetic resin or rubber, and has a first ventilation hole in the center thereof. 2b box-shaped, circular, etc. One end portion in the thickness direction (Z direction) of the elastic ventilation body 21 has a mounting portion 21 a with respect to the first interior surface 10 a of the chamber 10 . The elastic ventilation body 21 has the other end portion in the thickness direction (Z direction) as the displacement part 2a, and is brought into contact with the first non-opposing surface Br of the first plate-shaped member B carried in, whereby the elastic ventilation body The inner side of 21 forms the first space portion 4 . Therefore, due to the pressure difference between the internal pressure of the transformation chamber 1 and the internal pressure of the first space portion 4 , the elastic ventilation body 21 can undergo elastic compression deformation and expansion deformation in the Z direction. In addition, as another example of the elastic ventilation body 21, although not shown, a plate-shaped member having a plurality of first ventilation openings 2b, a porous member having a plurality of first ventilation openings 2b, or the like can be used instead of the annular member . In these cases, abnormal deformation and excessive deformation of the first plate-shaped member B can be detected by detecting the position of the first plate-shaped member B with the gap detection sensor disposed on the first inner surface 10a of the chamber 10 . . A deformation suppressing member (not shown) such as a stopper for mechanically preventing excessive deformation of the first plate-shaped member B may be provided. Furthermore, the 1st space part 4 and the 1st non-opposing surface Br of the 1st plate-shaped member B always communicate with the 1st ventilation opening 2b opened in the fluctuating part 2. Therefore, the first plate-like member B can adjust the displacement portion of the variable portion 2 by the pressure difference between the internal pressure of the first space portion 4 and the internal pressure of the variable pressure chamber 1 , which are lowered by the first internal pressure adjustment portion 6 to be described later. 2a Perform vacuum adsorption. Thereby, the first non-opposing surface Br of the first plate-shaped member B is detachably adsorbed and held at the displacement portion 2a by the increase of the internal pressure of the transformation chamber 1 and temporarily fixed. In addition, as another example of the variable part 2, although not shown in figure, it can also be changed to temporary fixation using an adhesive member, electrostatic adsorption, etc. instead of vacuum adsorption.

The holding part 3 is arrange|positioned so that it may contact the 2nd non-opposing surface Cr of the 2nd plate-shaped member C carried in along the thickness direction (Z direction). Furthermore, the holding part 3 has a holding part 3 a which is immovable in the thickness direction (Z direction) with respect to the second inner surface 10 b of the chamber 10 and is connected to the second non-moving part of the second plate-shaped member C to be carried in. The opposing surface Cr is in contact with each other. That is, the holding portion 3 is configured to hold the second plate-like member C immovably in the Z direction by bringing the second non-opposing surface Cr of the second plate-like member C into contact with the holding portion 3a. Preferably, a second space 7 is formed separately from the transformer chamber 1 between the holding portion 3 and the second inner surface 10b of the chamber 10 . By bringing the second non-opposing surface Cr of the second plate-shaped member C into contact with the holding portion 3 a of the holding portion 3 , the second space portion 7 is formed in an airtight shape. Moreover, it is preferable that the holding|maintenance part 3 has the 2nd ventilation opening 3b which makes the 2nd non-opposing surface Cr of the 2nd plate-shaped member C and the 2nd space part 7 communicate.

1 to 6 etc. as a specific example of the holding portion 3 is the holding ring body 31 fixed to the second interior surface 10b of the chamber 10, and the inner space of the holding ring body 31 becomes the second ventilation The opening 3b forms the second space portion 7 . For example, the holding ring body 31 in the illustrated example is formed in a frame shape, a ring shape, or the like from an elastically deformable material such as soft synthetic resin and rubber, or a non-deformable material such as hard synthetic resin and metal. Similar to the elastic ventilation body 21 of the variable portion 2, the holding ring body 31 can also be composed of a ring member such as a gasket or an O-ring. In this case, the holding ring body 31 can be elastically compressed and deformed in the Z direction. Expansion deformation. An end portion in the thickness direction (Z direction) of the annular body 31 for holding has a fixing portion 31 a for holding with respect to the second inner surface 10 b of the chamber 10 . The other end portion in the thickness direction (Z direction) of the holding portion 3 a on the holding ring body 31 is in contact with the second non-opposing surface Cr of the second plate-shaped member C carried in. Furthermore, since the second space portion 7 serving as the second ventilation port 3b of the holding portion 3 is always in communication with the second non-opposing surface Cr of the second plate-shaped member C, the second internal pressure adjusting portion 8 described later is used for descending the second space portion 7 . The pressure difference between the internal pressure of the second space portion 7 and the internal pressure of the transformation chamber 1 allows the second plate-shaped member C to be vacuum-adsorbed to the holding portion 3 a of the holding portion 3 . Thereby, the second non-opposing surface Cr of the second plate-shaped member C is detachably adsorbed and held at the holding portion 3 a by the increase in the internal pressure of the transformer chamber 1 and temporarily fixed. Moreover, as another example of the holding|maintenance part 3, although not shown in figure, it can also be changed to the temporary fixation by an adhesive member, electrostatic adsorption, etc. instead of vacuum adsorption. 1 to 3 and 14 , the dimension in the thickness direction (Z direction) of the elastic ventilation body 21 of the variable portion 2 is set to be substantially the same as the dimension in the Z direction of the holding annular body 31 of the holding portion 3 . . On the other hand, as shown in FIGS. 4 to 6 , FIG. 11 , and FIG. 13 , the dimension in the Z direction of the elastic ventilation body 21 of the variable part 2 is set to be larger than the Z direction of the holding ring body 31 of the holding part 3 . The dimensions are set to emphasize the amount of compressive deformation and the amount of expansion deformation of the variable portion 2 . In addition, as another example, although not shown in the drawings, it can be changed as follows: the dimension in the Z direction of the elastic ventilation body 21 of the variable part 2 shown in FIGS. 1 to 3 and FIG. 14 is larger than that of the holding part 3 Use the Z-direction dimension of the annular body 31 or the Z-direction dimension of the elastic ventilation body 21 of the variable portion 2 shown in FIGS. The Z-direction dimensions are roughly the same, etc.

The internal pressure of the second space portion 7 can be set from the atmospheric environment to a vacuum or a low-pressure environment close to vacuum or a predetermined high-pressure environment by the operation of the second internal pressure adjusting portion 8 (second driving source, second control valve 8b). Specifically, the negative pressure second fluid 8F discharged from the second flow path 8a or the positive pressure second fluid 8F supplied to the second flow path 8a is controlled by the operation control of the second drive source and the second control valve 8b. It is better to adjust the internal pressure of the second space part 7 step by step.

The control unit 9 is a controller having a control circuit (not shown) electrically connected to the chamber pressure adjusting unit 5 , the first internal pressure adjusting unit 6 , and the second internal pressure adjusting unit 8 , etc., respectively. Furthermore, it is electrically connected with the drive mechanism 10d which opens and closes the entrance 10c of the chamber 10. In addition to this, it is also electrically connected to a conveying mechanism or the like for moving the first plate-shaped member B and the second plate-shaped member C into and out of the transformer chamber 1 . The controller that becomes the control unit 9 performs the operation control in sequence according to the program preset in the control circuit (not shown) and at the preset timing sequence.

Moreover, the program of the control circuit set in the control part 9 is demonstrated as the manufacturing method of a microstructure by the microstructure manufacturing apparatus A. The manufacturing method of the microstructure using the microstructure manufacturing apparatus A of embodiment of this invention can be divided into a carrying-in process, a holding process, a room pressure adjustment process, and a carrying-out process. Specifically, as main steps, the method for producing a microstructure according to an embodiment of the present invention includes: a carrying-in step of carrying the first plate-shaped member B and the second plate-shaped member C into the transformer chamber 1; a holding step of carrying The first plate-shaped member B and the second plate-shaped member C are held in the transformer chamber 1 ; the chamber pressure adjustment step is to adjust the internal pressure of the transformer chamber; and the carry-out step is to carry out the first plate-shaped member B from the transformer chamber 1 and the second plate-shaped member C.

In the carrying-in step, as shown in Fig. 2(a), Fig. 2(b), Fig. 4(a), Fig. 8(a), Fig. 8(b), etc., the first plate is moved by the operation of the conveying mechanism. The shaped member B and the second plate-shaped member C are inserted into and accommodated in the transformer chamber 1 from the outer space of the chamber 10 . As shown in FIGS. 2( a ), 2 ( b ), 8 ( a ), 8 ( b ), etc., when the first plate-shaped member B and the second plate-shaped member C are in a separated state at the time of carrying in , a single carry-in process for placing either the first plate member B or the second plate member C into the transformer chamber 1 and two steps for placing the other into the transformer chamber 1 are required move-in process. In addition, as shown in FIG. 4( a ) and the like, when the first plate-shaped member B and the second plate-shaped member C are in a joined state at the time of loading, the concave and convex portions (the first joining concave and convex portion B1 , the second joining concave and convex portion B1 , the second joining concave and convex portions The first plate-shaped member B and the second plate-shaped member C, which are integrated by concavo-convex bonding, are placed in the transformer chamber 1 in a concave-convex-bonded state.

As shown in FIG. 2( c ), FIG. 4( a ), FIG. 8( c ), etc., in the holding step, the first non-opposing surface Br of the first plate-shaped member B is made to be parallel to the thickness direction (Z direction) of the first plate-shaped member B. The displacement part 2a of the variable part 2 abuts. At the time of this contact, the internal pressure of the first space part 4 is lowered by the discharge of the first fluid 6F based on the operation of the first internal pressure adjusting part 6 , and the first plate passes through the first vent 2 b of the variable part 2 . Preferably, the first non-opposing surface Br of the shaped member B is vacuum adsorbed to the displacement portion 2 a of the variable portion 2 . Therefore, the first non-opposing surface Br of the first plate-shaped member B and the displacement portion 2 a of the variable portion 2 are positioned and integrated so as not to be displaced in the direction (XY direction) intersecting the thickness direction (Z direction). change. Thereby, the 1st plate-shaped member B can move with respect to the 1st inner surface 10a of the chamber 10 with the deformation or movement of the displacement part 2a in the thickness direction (Z direction). The second non-opposing surface Cr of the second plate-shaped member C is brought into contact with the holding portion 3 a of the holding portion 3 in the thickness direction (Z direction). At the time of this contact, the internal pressure of the second space part 7 is lowered by the discharge of the second fluid 8F by the operation of the second internal pressure adjusting part 8 , and the second plate passes through the second vent 3 b of the holding part 3 . Preferably, the second non-opposing surface Cr of the shaped member C is vacuum-sucked to the holding portion 3 a of the holding portion 3 . Therefore, the second non-opposing surface Cr of the second plate-shaped member C and the holding portion 3 a of the holding portion 3 are positioned and integrated so as not to be displaced in the direction (XY direction) intersecting the thickness direction (Z direction) . Thereby, the second plate-shaped member C is held so as to be immovable in the thickness direction (Z direction) with respect to the second inner surface 10 b of the chamber 10 . In addition, when the holding portion 3 is elastically deformable, the second plate-shaped member C can be changed to be able to extend along the thickness of the second inner surface 10b of the chamber 10 along with the deformation of the holding portion 3a in the thickness direction (Z direction). direction (Z direction) to move. As shown in FIGS. 3( a ), 5 ( a ), 9 ( a ), etc., the first plate-shaped member B and the second plate-shaped member C close the inlet and outlet 10 c of the chamber 10 after such holding, and the chamber The transformer chamber 1 in the 10 is blocked from the external space of the chamber 10 to be in a hermetic state.

The step of adjusting the chamber pressure includes: at least by the action of the chamber pressure adjusting part 5, controlling a differential pressure process in which a pressure difference is generated between the internal pressure of the variable pressure chamber 1 and the internal pressure of the first space part 4; , the pressure bonding process of making the first plate member B and the second plate member C move relatively close to the opposite direction; through the pressure difference, the first plate member B and the second plate member C are moved towards the opposite direction The peeling process in which the directions move relatively apart; and the atmospheric opening process in which the internal pressure of the transformer chamber 1 is restored to the atmospheric pressure. As shown in Fig. 3(b), Fig. 5(b), Fig. 9(b), etc., during the differential pressure process, by the discharge or supply of the fluid 5F based on the operation of the chamber pressure adjusting part 5, the pressure transformation chamber is The internal pressure of either one of 1 or the first space portion 4 rises more than the internal pressure of the other. Thereby, a pressure difference is generated between the internal pressure of the transformation chamber 1 and the internal pressure of the first space portion 4 . At this time, in addition to the change in the internal pressure of the transformation chamber 1 based on the operation of the chamber pressure adjusting part 5 , the first space is simultaneously supplied or discharged by the supply or discharge of the first fluid 6F based on the operation of the first internal pressure adjusting part 6 . It is preferable to control the pressure difference between the internal pressure of the transformation chamber 1 and the internal pressure of the first space part 4 to be larger as the internal pressure of the part 4 changes. Moreover, when the holding portion 3 is elastically deformable, in addition to the change in the internal pressure of the first space portion 4 based on the operation of the first internal pressure adjustment portion 6 , the second internal pressure adjustment portion 8 The supply or discharge of the fluid 8F changes the internal pressure of the second space portion 7 , and controls the pressure difference between the internal pressure of the transformation chamber 1 and the internal pressure of the second space portion 7 to become larger.

During the pressure joining process, only by the discharge of the fluid 5F based on the operation of the chamber pressure adjusting part 5, or in addition to the supply of the first fluid 6F based on the operation of the first internal pressure adjusting part 6, The supply of the second fluid 8F by the operation of the second internal pressure adjusting portion 8 lowers the internal pressure of the transformation chamber 1 more than the internal pressure of the first space portion 4 and the internal pressure of the second space portion 7 . Due to the pressure difference thus generated, a pressing force for pressing the first plate-shaped member B and the displacement portion 2 a of the variable portion 2 toward the second plate-shaped member C in the thickness direction (Z direction) is generated. As shown in FIG. 3( b ) and the like, when the second opposing surface Cf of the second plate-shaped member C has a non-contact uneven portion (non-bonding uneven portion Cu) by this pressing force, the first plate-shaped member B has a The first opposing surface Bf is joined to the non-joining uneven portion Cu of the second plate-shaped member C and is pressed in the thickness direction (Z direction), so that the first opposing surface Bf follows the non-joining uneven portion Cu to become minute parts By overlapping the shapes of the non-joining portions Mf on the surfaces of Ma, the first plate-like member B is uniformly pressurized toward the non-joining uneven portions Cu of the second plate-like member C by the pressure difference (fluid).

In the peeling process, only by supplying the fluid 5F by the operation of the chamber pressure adjusting part 5, or by discharging the first fluid 6F by the operation of the first internal pressure adjusting part 6, by the second The discharge of the second fluid 8F due to the operation of the internal pressure adjusting portion 8 increases the internal pressure of the transformation chamber 1 more than the internal pressure of the first space portion 4 and the internal pressure of the second space portion 7 . Due to the resulting pressure difference, an attractive force that attracts the first plate-like member B along with the displacement portion 2 a of the variable portion 2 toward the first space portion 4 in the thickness direction (Z direction) is generated. As shown in FIG. 5( c ) and the like, by this attractive force, the first opposing surface Bf of the first plate-shaped member B has a first joining concavo-convex portion B1 as one of the concave-convex portions of the concave-convex joining, and the second plate-like member When the second opposing surface Cf of C has the second joint concavo-convex portion C1 as the other of the concave-convex portion, the first joint concavo-convex portion B1 of the first plate-shaped member B is relative to the second joint concavo-convex portion of the second plate-shaped member C. The portion C1 is pulled apart in the thickness direction (Z direction), thereby peeling the first joining concavo-convex portion B1 from the second joining concavo-convex portion C1. Furthermore, when there is a gap E between the first plate-shaped member B and the second plate-shaped member C, as shown in the example of the figure, the positive pressure fluid 5F intrudes into the gap E, and the second plate-shaped member B is generated. A repulsive force for pushing apart the engaging concave-convex portion B1 and the second engaging concave-convex portion C1 of the second plate member C relatively. In addition, the position of the first non-opposing surface Br and the like of the first plate-shaped member B is detected by the gap detection sensor disposed on the first inner surface 10a of the chamber 10, and the detection value thereof is monitored, thereby enabling detection of The progress of joining or peeling of the concavo-convex portion (non-joining concave-convex portion Cu, the first joining concave-convex portion B1 , and the second joining concave-convex portion C1 ), and the completion of the joining or peeling.

As shown in FIG. 3( c ), FIG. 6( a ), FIG. 10( a ), etc., the atmosphere opening process stops the discharge or supply of the fluid 5F based on the operation of the chamber pressure adjusting portion 5 , and is opened by the drive mechanism 10 d The inlet/outlet 10c of the chamber 10 releases the fluid 5F filled in the transformer chamber 1 to the outer space of the transformer chamber 1 and the like, thereby returning the internal pressure of the transformer chamber 1 to atmospheric pressure.

3( c ), FIG. 6( b ), FIG. 6( c ), FIG. 10( b ), FIG. 10( c ), etc., the unloading step causes the operation of the first internal pressure adjusting portion 6 and the second internal pressure The operation of the pressure adjustment unit 8 is sequentially stopped, and the first plate-shaped member B and the second plate-shaped member C are extracted from the transformation chamber 1 to the outer space of the chamber 10 by the operation of the conveying mechanism. As shown in FIG.3(c) etc., when the 1st plate-shaped member B and the 2nd plate-shaped member C are in the joined state at the time of carrying out, the uneven part (non-joining uneven part Cu) is concave-convex bonded and integrated The first plate-shaped member B and the second plate-shaped member C are extracted to the outside of the transformer chamber 1 in a state of concave-convex bonding. Moreover, as shown in FIGS. 6(b), 6(c), 10(b), 10(c), etc., the first plate-shaped member B and the second plate-shaped member C are in a separated state at the time of loading in. In this case, a single carry-out process for extracting either the first plate-shaped member B or the second plate-shaped member C to the outside of the transformer chamber 1 and a process for extracting the other to the transformer chamber 1 are required The external secondary move-out process.

Next, specific examples (first to third embodiments) and modified examples (fourth to seventh embodiments) of the microstructure manufacturing apparatus A according to the embodiment of the present invention will be described. The microstructure manufacturing apparatus A1 of the first embodiment shown in FIGS. 1 to 3 manufactures microparts that are joined (mounted) between the first plate-shaped member B and the second plate-shaped member C in a sandwiched manner The layered microstructure M1 of Ma serves as a bonding device for the microstructure M. By the relative approaching movement of the first plate-shaped member B and the second plate-shaped member C, the first plate-shaped member B will be arranged on the first opposing surface Bf of the first plate-shaped member B or the second opposing surface Cf of the second plate-shaped member C The non-contact concavo-convex portion (non-joining concavo-convex portion Cu) of any one of the minute parts Ma is joined and integrated with the other one. In the case of the illustrated example, the first opposing surface Bf of the first plate-shaped member B and the second opposing surface Cf of the second plate-shaped member C are provided with a fixing layer D1 such as an adhesive, an adhesive chuck, etc. to hold the The chuck D2 serves as the holding mechanism D for the minute parts Ma. The plurality of minute parts Ma are arranged in parallel, respectively. In the initial state (carrying-in step) before joining shown in FIG. 2( a ) and FIG. 2( b ), the micro parts Ma are immovably arranged on the first place by the holding mechanism D (fixed layer D1 , holding chuck D2 ). The second opposing surfaces Cf of the two plate-shaped members C have non-contact concavo-convex portions (non-joining concave-convex portions Cu). In the following steps from the holding step shown in FIG. 3( a ) to the chamber pressure adjustment step (differential pressure process, pressurization bonding process) shown in FIG. 3( b ), by the first plate based on the fluid differential pressure The relative approaching movement of the plate-shaped member B causes the first opposing surface Bf of the first plate-shaped member B to engage with the non-bonding concave-convex portion Cu of the second plate-shaped member C to be pressed in the thickness direction (Z direction). Along with this, the first opposing surface Bf overlaps the non-joining concave-convex portion Cu so as to follow the shape of the non-joining portion Mf that becomes the surface of the minute component Ma, and thereby moves toward the non-joining concave-convex portion Cu by the pressure difference (fluid). Pressurized equally. Therefore, the minute parts Ma are sandwiched between the first plate-shaped member B and the second plate-shaped member C and integrated to form a layered body.

Furthermore, in the illustrated example, the transformer chamber 1 of the chamber 10 is of a split type. With regard to the split-type transformer chamber 1 , the chamber 10 is divided into a first chamber 11 and a second chamber 12 , and a port 10 c is formed between the divided first chamber 11 and the second chamber 12 . A sealing material 13 composed of a square-shaped, annular gasket, an O-ring, or the like is inserted into the inlet and outlet 10c. The first chamber 11 and the second chamber 12 are relatively close to each other by the drive mechanism 10d, and the inlet and outlet 10c are airtightly closed by the sealing material 13, so that the transformer chamber 1 can be opened and closed freely and has a sealed structure. In the illustrated example, only the first chamber 11 on the upper side is reciprocated with respect to the second chamber 12 on the lower side, but it can be changed to make only the second chamber 12 on the lower side, or the first chamber 11 and the The second chamber 12 has a structure other than the example shown in the figure, such as reciprocating movement of both of the second chambers 12 .

The microstructure manufacturing apparatus A2 of the second embodiment shown in FIGS. 4 to 6 is different from the first embodiment in that the structure is a separation device, and the other structure is the same as that of the first embodiment, and the separation device peels off as a The microstructures M are arranged on the concavo-convex portions (first joining concavo-convex portion B1 , second joining concavo-convex portion C1 ) of the first plate-like member B and the second plate-like member C to be joined to each other. By the relative separation movement of the first plate-shaped member B and the second plate-shaped member C, such as the peeling of the forming die Mb and the forming substrate Mc that become the micromolding body M2, and the microparts Ma and the adhesive chuck that become the microstructure M1 Such as peeling of the holding mechanism, etc., the first joint concavo-convex portion B1 arranged on the first opposing surface Bf of the first plate-shaped member B and the second opposing portion of the second plate-like member C, which are joined to each other in a concavo-convex shape, are separated. The second joint concavo-convex portion C1 of the surface Cf. In the case of the illustrated example, a separate type in which the forming die Mb is arranged on the first plate-like member B and the forming substrate Mc is arranged on the second plate-like member C is shown. In a state in which the concavo-convex pattern of the forming mold Mb is transferred to the forming substrate Mc by nanoimprint molding or the like, the forming mold Mb and the forming substrate Mc are joined to each other in concavities and convexities to form a transportable integrated laminate. The molded substrate Mc has a resin layer Me that is pattern-transferred by light, heat, or the like to serve as the second bonding concavo-convex portion C1 on the surface layer of the substrate Md made of a hard material. Furthermore, on the first opposing surface Bf of the first plate-shaped member B and the second opposing surface Cf of the second plate-shaped member C, a holding chuck D2 such as an adhesive chuck, and a fixing layer D1 such as an adhesive are provided as minute The holding mechanism D of the molded object M2.

In the initial state (carrying-in step) at the time of joining shown in FIG. 4( a ), the first back surface B2 of the forming mold Mb that becomes the first joining concave-convex portion B1 is held by the holding mechanism D (holding chuck D2 , fixing layer D1 ) ) is arranged on the first opposing surface Bf of the first plate-shaped member B so as to be immovable. The first back surface C2 of the molding substrate Mc serving as the second bonding concavo-convex portion C1 is immovably arranged on the second opposing surface Cf of the second plate member C by the holding mechanism D (holding chuck D2, fixing layer D1). In the following chamber pressure adjustment steps (differential pressure process, peeling process) shown in FIGS. 5( b ) and 5( c ), by the relative separation movement of the first plate-like member B based on the fluid differential pressure, The forming die Mb that becomes the first joining concavo-convex portion B1 is pulled apart from the forming substrate Mc that becomes the second joining concavo-convex portion C1 in the thickness direction (Z direction).

Furthermore, in the illustrated example, between the first plate-like member B and the second plate-like member C, a plurality of first joining concavo-convex portions B1 (molding die Mb) and The second joining concavo-convex portion C1 (molding substrate Mc) has a frame-shaped outer gap E1 and a plurality of penetration gaps E2 passing linearly in both directions in the XY direction. Thereby, the positive pressure fluid 5F not only flows into the outer gap E1 but also penetrates into the plurality of penetration gaps E2, respectively, and thus generates a repulsive force that pushes the first plate-shaped member B and the second plate-shaped member C apart as a whole.

The microstructure manufacturing apparatus A3 of the third embodiment shown in FIGS. 7 to 10 is different from the first embodiment in that the structure is a transfer device, and the other structure is the same as that of the first embodiment. A transfer-type microstructure M1 in which the microparts Ma arranged (mounted) on either the first plate-shaped member B and the second plate-shaped member C as the microstructure M is transferred to the other is produced. By the relative approach movement and separation movement of the first plate-shaped member B and the second plate-shaped member C, the second pair of the first opposing surface Bf of the first plate-shaped member B or the second plate-shaped member C The non-contact concavo-convex portion (non-joining concavo-convex portion Cu) of the micro parts Ma of any one of the placement surfaces Cf is reversed and transferred to the other. In the case of the illustrated example, the first opposing surface Bf of the first plate-shaped member B is set as the transfer destination of the minute parts Ma, and has a strong bonding surface D3 serving as the holding mechanism D of the minute parts Ma. The second opposing surface Cf of the second plate-shaped member C is set as a transfer source of the minute parts Ma, and has a weak bonding surface D4 serving as a holding mechanism D of the minute parts Ma. The plurality of minute parts Ma are arranged in parallel, respectively. The strong adhesive surface D3 and the weak adhesive surface D4 are holding chucks D2 that hold the minute parts Ma detachably and temporarily fix them. In the holding chuck D2, it is preferable to use an adhesive chuck based on an adhesive member that can easily control the holding force of the minute parts Ma. At this time, as the strong adhesive surface D3, an adhesive member having a strong adhesive force is used, and as the weak adhesive surface D4, an adhesive member having a weak adhesive force is used. In addition, as another example, instead of the adhesive chuck, it is possible to change to a vacuum chuck that controls the strength of the suction force, or an electrostatic chuck that controls the strength of the electrostatic suction force.

In the initial state (carrying-in step) before transfer shown in FIGS. 8( a ) and 8 ( b ), the joint portion Mr that becomes the back surface of the plurality of minute parts Ma is held by the holding mechanism D (holding chuck D2 , The weak bonding surface D4) is arranged on the second opposing surface Cf of the second plate-shaped member C so as to be immovable. In the following steps from the holding step shown in FIG. 9( a ) to the chamber pressure adjustment step (differential pressure process, pressurization bonding process) shown in FIG. 9( b ), by the first plate based on the fluid differential pressure The relative approaching movement of the shaped member B causes the holding mechanism D (strong adhesive surface D3 ) of the first opposing surface Bf to be integrated with the non-joining portion Mf which is the surface of the plurality of minute parts Ma in the thickness direction (Z direction). change. After that, in the chamber pressure adjustment step (peeling process) shown in FIG. 9( c ), by the relative separation movement of the first plate-shaped member B based on the fluid differential pressure, the back surfaces (joint parts of the plurality of minute parts Ma) are separated. Mr) is pulled away in the thickness direction (Z direction) from the holding mechanism D (weak bonding surface D4 ) of the second opposing surface Cf. Thereby, the front and back of the plurality of microstructures M1 are reversed and transferred from the second plate-shaped member C to the first plate-shaped member B without changing the arrangement state.

The microstructure manufacturing apparatus A4 of the fourth embodiment shown in FIGS. 11( a ) to 11 ( c ) is different from the first to third embodiments described above in that the structure is a partially openable and closed type transformer chamber 1 except Other structures are the same as those of the first to third embodiments. In the illustrated example, the case of the separation device of the second embodiment is shown. A port 10c is opened in a part of the box-shaped chamber 14, and the door leaf 14a is opened and closed with respect to the port 10c by the drive mechanism 10d. As a result, a part of the transformer chamber 1 is configured to be freely openable and closable and has a sealed structure.

The microstructure manufacturing apparatus A5 of the fifth embodiment shown in FIGS. 12( a ) to 12 ( c ) is separated and disposed between the first plate-shaped member B and the second plate-shaped member C by the movement of the variable portion 2 The structure of the concavo-convex part for joining (the first joining concavo-convex part B1, the second joining concave-convex part C1) is different from the second and third embodiments described above, and the other structures are the same as those in the second and third embodiments same. In the illustrated example, the case of the separation device of the second embodiment is shown. The movable variable portion 2 is constituted by a lift ventilation body 22 supported so as to be able to reciprocate in the Z direction with respect to the first interior surface 10 a of the chamber 10 . The elevating ventilation body 22 has a ventilation hole 2c corresponding to the first ventilation opening 2b which communicates the first non-opposing surface Br of the first plate-shaped member B and the first space portion 4 . For example, the lift ventilation body 22 is formed of a plate-shaped member formed in a square plate shape, a circular plate shape, or the like from an indeformable material such as hard synthetic resin or metal, and has a ventilation hole 2c opened in the center thereof. The side surface of the lift ventilation body 22 has a sliding part 22a, the sliding part 22a is between the first interior surface 10a and the second interior surface 10b of the chamber 10, along the third interior surface 10e formed in the Z direction, along the Z direction It can move freely and is supported in an airtight state. The third inner surface 10e of the chamber 10 has a limiter 10f on one side and a limiter 10g on the other side protruding toward the lift ventilation body 22 . The elevating ventilation body 22 moving in the Z direction is in contact with the limiter 10f on one side or the limiter 10g on the other side, thereby restricting the moving range of the lifting ventilation body 22 . The lift ventilation body 22 makes contact with the first non-opposing surface Br of the loaded first plate-shaped member B as a displacement portion 2 a at the front end portion in the thickness direction (Z direction), whereby the lift ventilation body 22 and the chamber The first space portion 4 is formed between the first interior surfaces 10a of the 10 . Therefore, due to the increase in the internal pressure of the transformation chamber 1 due to the inflow of the positive pressure fluid 5F and the internal pressure difference of the first space portion 4 , the elevating ventilation body 22 moves in the Z direction to displace the first plate-shaped member B therewith. The portion 2a moves together toward the first space portion 4 . Thereby, the 1st plate-shaped member B is pulled apart from the 2nd plate-shaped member C. In addition, as another example of the elevating ventilation body 22, although not shown, a plate-shaped member having a plurality of ventilation holes 2c, a porous plate-shaped member having a plurality of ventilation holes 2c, etc. can be used instead of having one ventilation hole 2c. plate-like components. Furthermore, instead of the sliding portion 22a of the elevating ventilation body 22, the sliding portion 22a can be supported so as to be movable along the third indoor surface 10e, and can also be changed to a support structure in which a thin plate-shaped flexible member such as stainless steel can be elastically deformed at the center of the flexible member. The lift ventilation body 22 is supported in a floating island shape, and the lift ventilation body 22 is supported so as to be able to reciprocate in the Z direction by the elastic deformation of the flexible member. In the case of this floating island shape, by attaching the outer periphery of the flexible member to the third inner surface 10e of the chamber 10, the back surface of the flexible member is separated from the transformer chamber 1 by the first space portion 4 and provided in a gaseous state dense.

The microstructure manufacturing apparatus A6 of the sixth embodiment shown in FIGS. 13( a ) to 13 ( c ) has the first plate-shaped member B and the second plate-shaped member C formed with through holes h communicating with the inner gap E3 This structure is different from the aforementioned second and third embodiments, and other structures are the same as those of the second and third embodiments. In the illustrated example, the case of the separation device of the second embodiment is shown. The through-hole h is opened in either or both of the first plate-shaped member B or the second plate-shaped member C so as to be separated from the first space portion 4 and the second space portion 7, and the positive pressure fluid 5F changes from the variable pressure. The chamber 1 penetrates into the inner gap E3 through the through hole h. Furthermore, in the illustrated example, between the first plate-shaped member B and the second plate-shaped member C, a plurality of first joining concavities and convexities are arranged side by side at predetermined intervals in the circumferential direction with the inner gap E3 as the center, respectively. The portion B1 and the second joint concavo-convex portion C1 have an outer gap E1 and a plurality of penetration gaps (not shown) passing linearly along the radial direction centered on the inner gap E3. A through hole h is opened in the center of the first plate-shaped member B facing the first space portion 4 . An introduction path 5c through which the positive pressure fluid 5F flows is formed on the first inner surface 10a of the chamber 10 facing the through hole h so as to communicate with the through hole h, whereby the positive pressure fluid 5F is introduced from the outflow port of the introduction path 5c to the through hole h. In addition, similarly to the aforementioned second embodiment, the concavo-convex portions (the first joining concavo-convex portion B1 and the second joining concavo-convex portion C1 ) that are joined to each other by the deformation of the variable portion 2 are peeled off. However, since the outflow port of the introduction path 5c opens on the first inner surface 10a of the chamber 10, the passage from the outflow port of the introduction path 5c to the through hole h needs to be airtightly separated from the first space 4. Therefore, in the fluctuating portion 2 of the illustrated example, the outer annular member 23 other than the elastic ventilator 21 corresponding to the first embodiment is separately provided so as to surround the passage from the outflow port of the introduction path 5c to the through hole h There is an inner annular member 24 . The first space portion 4 is formed between the outer annular member 23 and the inner annular member 24 . In addition, as other examples of the elastic ventilation body 21, although not shown, a plate-shaped member having a plurality of first ventilation openings 2b, a porous member having a plurality of first ventilation openings 2b, or the like can be used instead of the outer annular shape. Member 23 , inner annular member 24 . Thereby, the positive pressure fluid 5F not only flows into the outer gap E1, but also penetrates into the inner gap E3 through the introduction path 5c, the inner passage of the inner annular member 24, and the through hole h, and flows from the inner gap E3 through a plurality of penetration gaps ( (not shown), therefore, a repulsive force that pushes the first plate-shaped member B and the second plate-shaped member C apart as a whole is generated.

The microstructure manufacturing apparatus A7 of the seventh embodiment shown in FIGS. 14( a ) to 14 ( c ) has a structure in which the adhesive force of the strong bonding surface D3 and the weak bonding surface D4 of the holding mechanism D is controlled by temperature change Different from the third embodiment described above, other structures are the same as those of the third embodiment. When the strong adhesive surface D3 and the weak adhesive surface D4 are composed of adhesive members, the adhesive force can be increased by heating, and the adhesive force can be decreased by cooling. In the illustrated example, the heating or cooling temperature changing members controlled by the operation of the control unit 9 are provided to the first opposing surface Bf of the first plate-shaped member B that is the transfer destination of the minute parts Ma, respectively. Both the strong adhesive surface D3 and the weak adhesive surface D4 of the second opposing surface Cf of the second plate-shaped member C serving as the transfer source of the minute parts Ma are subjected to temperature control. On the first interior surface 10a of the chamber 10 facing the first non-opposing surface Br of the first plate member B in the Z direction, the first temperature changing member G1 is provided near the strong bonding surface D3 with the heat insulating material B4 interposed therebetween. . On the second interior surface 10b of the chamber 10 facing the second non-opposing surface Cr of the second plate-shaped member C in the Z direction, the second temperature changing member G2 is provided in the vicinity of the weak bonding surface D4 with the heat insulating material B5 interposed therebetween. . The first temperature change member G1 and the second temperature change member G2 have any one or both of a heating function such as a heater and a cooling function such as refrigerant piping. Therefore, in the chamber pressure adjustment step (differential pressure process, pressurized joining process) shown in FIG. 14( b ), by the relative approach movement of the first plate-like member B based on the fluid differential pressure, the first opposing surface When the strong bonding surface D3 of Bf is joined to the surfaces (non-joining portions Mf) of the plurality of minute parts Ma in the thickness direction (Z direction), the first temperature changing member G1 is heated. Thereby, the adhesive force of the strong adhesive surface D3 is increased, and the surfaces (non-joining portions Mf) of the plurality of minute components Ma can be firmly joined. At the same time, since the weakly bonding surface D4 is cooled by the second temperature changing member G2, the adhesive force of the weakly bonding surface D4 decreases, and the back surfaces (joint portions Mr) of the plurality of minute parts Ma are easily peeled off from the weakly bonding surface D4. Therefore, in the chamber pressure adjustment step (peeling process) shown in FIG. 14( c ), by the relative separation movement of the first plate-shaped member B based on the fluid differential pressure, the back surface (joint portion) of the plurality of minute parts Ma is separated. Mr) smoothly pulled away from the weak joint D4. As a result, it is possible to control the bonding force to be easier for bonding and peeling than at room temperature, and to shorten the processing time required for bonding or peeling in the chamber 10 . In addition, as another example, although not shown in the figure, the adhesive force of either the strong adhesive surface D3 or the weak adhesive surface D4 can be controlled by temperature change.

According to the microstructure manufacturing apparatus A and the manufacturing method of the microstructure according to the embodiment of the present invention, by accommodating the first plate-shaped member B and the second plate-shaped member C in the transformer chamber 1, the first plate-shaped member The first non-opposing surface Br of B is in deformable contact or movable contact with the displacement portion 2 a of the variable portion 2 . Therefore, the first plate-shaped member B can move in the thickness direction (Z direction) with respect to the first inner surface 10 a of the chamber 10 . The second non-opposing surface Cr of the second plate-shaped member C is in contact with the holding portion 3 a of the holding portion 3 and is supported on the second inner surface 10 b of the chamber 10 . In this accommodated state, the internal pressure of the first space portion 4 is increased more than the internal pressure of the transformer chamber 1 by the chamber pressure adjusting portion 5 , whereby the first plate-shaped member B and the displacement portion of the variable portion 2 are displaced. 2a are moved toward the second plate-shaped member C together. Therefore, when either the first opposing surface Bf of the first plate-shaped member B or the second opposing surface Cf of the second plate-shaped member C has a concave-convex portion (non-bonding concave-convex portion Cu), the other The first plate-shaped member B is uniformly pressurized toward the second plate-shaped member C by the pressure difference (fluid) by being superimposed so as to follow the uneven surface shape of the uneven portion (non-joining uneven portion Cu). In addition, the internal pressure of the transformation chamber 1 is lowered more than the internal pressure of the first space portion 4 by the chamber pressure adjusting portion 5, and the first plate-shaped member B faces the first space together with the displacement portion 2a of the variable portion 2. Section 4 moves. Therefore, both the first opposing surface Bf of the first plate-shaped member B and the second opposing surface Cf of the second plate-shaped member C have concavo-convex portions (first joining concavo-convex portion B1, second joining concavo-convex portion C1 ) At the time, the concavo-convex portion (first engagement concave-convex portion B1 ) of the first plate-shaped member B is pulled away from the concave-convex portion (second engagement concave-convex portion C1 ) of the second plate-shaped member C. Therefore, it is possible to change the joining of the concavo-convex portions (non-joining concavo-convex portion Cu) separated by the control of the internal pressure difference, additional pressing, and the joining of the concavo-convex portions to be joined (the first joining concavo-convex portion B1, the second joining concavo-convex portion C1). Detached reverse operation. As a result, compared with the conventional products having only the separation function of separating the mold from the object to be molded, it can be used as the object to be separated only by changing the setting of the internal pressure difference between the transformer chamber 1 and the first space portion 4 . The bonding device of the concave-convex portion (non-joining concave-convex portion Cu), the additional pressing device, or the separation device of the joined concave-convex portion (first joining concave-convex portion B1, second joining concave-convex portion C1), are excellent in ease of use. In particular, in the joining and additional pressing of the separated concavo-convex portion (non-joining concave-convex portion Cu), the first plate-shaped member B can be pressed uniformly along the surface shape of the concave-convex portion (non-joining concave-convex portion Cu). Therefore, even if there is a local thickness unevenness in the first plate-shaped member B and the second plate-shaped member C, or the minute structures M are formed in uneven shapes between the first plate-shaped member B and the second plate-shaped member C Even in the case of sandwiching and joining, the joining can be performed in a uniform pressurized state without concentrating the pressure only on the convex portions of the microstructure M and the like. Thereby, the breakage of the convex portion can be prevented, and high-precision joining and additional pressing can be realized.

Further, the first plate-shaped member B and the second plate-shaped member C have concavo-convex portions (first engaging concave-convex portion B1, second engaging concave-convex portion C1) in which the first plate-like member B and the second plate-like member C are joined in a concavo-convex shape. It is preferable to move the first plate-shaped member B toward the first space 4 together with the displacement portion 2a of the variable portion 2 by operating to increase the internal pressure of the transformation chamber 1 more than the internal pressure of the first space portion 4 . At this time, by increasing the internal pressure of the transformation chamber 1 more than the internal pressure of the first space portion 4 , the first plate-shaped member B and the displacement portion 2 a of the variable portion 2 extend along the thickness toward the first space portion 4 . direction (Z direction) to move. Therefore, the concavo-convex portion of the first plate-shaped member B (the first engagement concave-convex portion B1 ) is pulled away from the concave-convex portion of the second plate-shaped member C (the second engagement concave-convex portion C1 ). Therefore, the concavo-convex portions (the first joint concavo-convex portion B1 and the second joint concavo-convex portion C1 ) of the first plate-like member B and the second plate-like member C can be peeled off without being deformed (collapsed). As a result, even the protrusion amount of the concavo-convex portions (the first joining concavo-convex portion B1 and the second joining concavo-convex portion C1 ) becomes longer compared to the conventional product in which the concavo-convex pattern is drawn out of the mold obliquely from the concavo-convex pattern transferred to the object to be molded. , can also prevent the shape deformation accompanying peeling. Therefore, when used in imprint molding including nanoimprinting, it is possible to create a highly accurate concavo-convex pattern without damaging the concavo-convex pattern of the concavo-convex portions (first bonding concavo-convex portion B1 , second joining concavo-convex portion C1 ). In addition, in the case of a conveying device or the like that peels the micro components Ma arranged in parallel from the adhesive chuck and transfers the micro components Ma, it is possible to perform the delivery with high precision without damaging the micro components Ma.

It is preferable to further comprise the 1st internal pressure adjustment part 6 which reduces the internal pressure of the 1st space part 4. At this time, when the internal pressure of the transformer chamber 1 is increased, the internal pressure of the first space portion 4 is decreased by the first internal pressure adjustment portion 6, and the internal pressure of the transformer chamber 1 and the internal pressure of the first space portion 4 are reduced. pressure difference becomes larger. Therefore, the attractive force for attracting the variable portion 2 toward the first space portion 4 increases. Therefore, the concavo-convex portions of the first plate-like member B and the second plate-like member C (the first joining concavo-convex portion B1 and the second joining concavo-convex portion C1 ) which are joined to each other in concave and convex can be smoothly peeled off. As a result, the peeling ability can be improved. In particular, by either or both of the chamber pressure adjustment unit 5 (the drive source for the chamber pressure, the control valve 5b for the chamber pressure) or the first internal pressure adjustment unit 6 (the first drive source, the first control valve 6b ). When the internal pressure of the transformer chamber 1 and the internal pressure of the first space portion 4 are relatively adjusted step by step, the concave and convex portions (the first joint concave and convex portion B1, the second joint concave and convex portion B1, the second joint concave and convex portion B1 and the second joint concave and convex portion can be peeled off more smoothly. C1). In addition, the first non-opposing surface Br of the first plate-shaped member B can be vacuum adsorbed to the displacement portion 2a of the variable portion 2 by the pressure difference between the internal pressure of the transformer chamber 1 and the internal pressure of the first space portion 4 . . Thereby, by the pressure difference between the internal pressure of the transformation chamber 1 and the internal pressure of the first space portion 4, the first plate-like shape that moves toward the first space portion 4 together with the displacement portion 2a of the variable portion 2 can be adsorbed and held. Component B.

Further, it is provided with an airtight second space portion 7 formed between the second inner surface 10b of the chamber 10 and the holding portion 3, and a second internal pressure adjusting portion 8 for reducing the internal pressure of the second space portion 7. good. At this time, the internal pressure of the first space portion 4 is lowered at the same time as the internal pressure of the transformer chamber 1 rises or before the rise of the internal pressure of the transformer chamber 1, and the internal pressure of the transformer chamber 1 and the first A pressure difference occurs between the internal pressures of the space portion 4 . Therefore, the second non-opposing surface Cr of the second plate-shaped member C is vacuum adsorbed to the holding portion 3 a of the holding portion 3 by the pressure difference. Thereby, the second plate-shaped member C is adsorbed and held by the holding portion 3a so as to be immovable. Therefore, the second plate-shaped member C can be surely fixed to the holding portion 3 a of the holding portion 3 . As a result, the concavo-convex portions of the first plate-like member B and the second plate-like member C (the first joining concavo-convex portion B1 and the second joining concavo-convex portion C1 ) can be reliably peeled off.

In addition, it is preferable to further have a gap E between the first plate-shaped member B and the second plate-shaped member C through which the fluid 5F supplied from the chamber pressure adjusting portion 5 to the transformation chamber 1 can penetrate. At this time, due to the pressure difference between the transformation chamber 1 and the first space portion 4, an attractive force that attracts the variable portion 2 toward the first space portion 4 is generated, and at the same time, a positive pressure is supplied from the chamber pressure adjustment portion 5 to the transformation chamber 1. The pressurized fluid 5F intrudes into the gap E to generate a repulsive force that pushes the uneven portions (the first engaging uneven portion B1 , the second engaging uneven portion C1 ) of the first plate-shaped member B and the second plate-shaped member C relatively apart. Therefore, the concavo-convex portion (the first joining concavo-convex portion B1 and the second joining concavo-convex portion C1 ) can be peeled off more smoothly by the interaction of the attractive force and the repulsive force. As a result, further improvement in peeling ability can be achieved.

Further, either the first plate-shaped member B or the second plate-shaped member C has a strong adhesive surface D3, and the other has a plurality of microstructures M1 detachably arranged in parallel with the weak adhesive surface D4 interposed therebetween, and the control The portion 9 is preferably controlled in such a manner that the internal pressure of the first space portion 4 rises more than the internal pressure of the transformation chamber 1 by the operation of the chamber pressure adjusting portion 5, and the first plate-like member B is thus directed toward the first plate-like member B. The two plate-shaped members C move, and then the internal pressure of the transformer chamber 1 rises more than the internal pressure of the first space portion 4 , whereby the first plate-shaped member B moves toward the first space portion 4 . At this time, the first plate-shaped member B moves toward the second plate-shaped member C by increasing the internal pressure of the first space portion 4 more than the internal pressure of the transformation chamber 1 . Therefore, the first plate-shaped member B and the second plate-shaped member C are close to each other, and the surfaces (non-bonding uneven portions Cu) of the plurality of minute structures M1 are bonded to the strong bonding surface D3. Next, by increasing the internal pressure of the transformation chamber 1 more than the internal pressure of the first space portion 4 , the first plate-shaped member B moves toward the first space portion 4 . Therefore, the first plate-shaped member B is separated from the second plate-shaped member C, and the back surfaces (joint portions Mr) of the plurality of minute structures M1 are pulled apart from the weakly bonded surface D4. Therefore, the front and back of the plurality of microstructures M1 can be reversed and transferred from either the first plate-shaped member B or the second plate-shaped member C to the other without changing the arrangement state. As a result, the transfer of the plurality of microstructures M1 can be performed with high accuracy without being damaged, and by inverting the front and back, the back surfaces (joint portions Mr. ) exposed.

In addition, in the aforementioned embodiments (the first to seventh embodiments), only the case where the first plate-shaped member B and the second plate-shaped member C are rectangular is shown in the illustrated example, but it is not limited to Here, in addition to a rectangle, a circle or the like may be used. Furthermore, in the illustration example of the second embodiment, only the split type of the micromolded object M2 is shown, but it is not limited to this, and either the first plate-shaped member B or the second plate-shaped member C may be used. The entirety of one becomes the molding die Mb, and the entirety of the other becomes an integral form of the molding substrate Mc. In addition, in the illustration examples of the fourth to sixth embodiments, only a modification of the second embodiment (separation device) is shown, and in the illustration examples of the seventh embodiment, only the third embodiment ( A modification of the transfer device), but not limited to this, the fourth to seventh embodiments may be the first embodiment (bonding device), the second embodiment (separating device), the first embodiment (separating device), and the The third embodiment (transfer device).
