Technical field
The present invention relates to the development processing apparatus and the developing method of substrate.
Background technology
For example in the photo-mask process of process for fabrication of semiconductor device, for example to carry out the development treatment of developing to according to the wafer behind the set pattern exposure.This development treatment is carried out in development processing apparatus usually.In this development processing apparatus, wafer is rotated under the driving of rotating suction disc, supply with developer solution by the developer solution supply nozzle to this wafer, form the developer solution liquid film at front wafer surface, thereby carry out the development of wafer.
But above-mentioned development processing apparatus need make the wafer rotation, thereby rotating suction disc must use the rotation motor of high torque (HT).Therefore, motor will take very big space, causes the development processing apparatus volume bigger.In addition, it is big that motor rotates needed power consumption, thereby operating cost is also higher.
For this reason, can consider to adopt the what is called development processing apparatus without spin that does not make wafer rotation.At present, the someone proposes to carry out the conveying of wafer with the tumbling-type conveyor that a plurality of roller bearings constitute, thereby makes wafer from the scheme (TOHKEMY 2001-87721 communique) of developer solution supply nozzle below by wafer is developed.
But in the development processing apparatus that wafer is developed with rolling mode of movement transfer wafers, roller bearing will contact with the lower surface that for example is developed the wafer that liquid stains.Therefore, roller bearing can be stained, and the dirt on the roller bearing can be attached on other position of wafer or other wafer and cause polluting and enlarge, and the generation source of particulate enlarges.So, will produce particulate in a large number, and for example cause wafer contaminated before developing, cause the generation of developing defect.
In addition, as development processing apparatus, people use is that for example move and to the whole positive device of supplying with developer solution of wafer in the front that wafer, developer solution supply nozzle limit output developer solution edge.
But in this development processing apparatus, for example the developer solution supply nozzle is to supply with developer solution while moving, thereby developer solution can flow on wafer, is easy to generate little great waves.Therefore, the developer solution instability on the wafer, it is unstable to cause sometimes developing.For addressing this problem, someone proposes for example to be provided with the poriness plate between developer solution supply nozzle and wafer, make developer solution through the poriness plate current to wafer, developer solution is clipped in scheme (TOHKEMY 2005-51008 communique) between poriness plate and the wafer.
But this technology too, for example because the speed composition that developer solution has set direction, thereby can produce " sliding resistance " on the interphase of poriness plate and developer solution when supplying with developer solution.This sliding resistance meeting is flowed the developer solution on the wafer and form convection current in developer solution.If produce convection current in the developer solution as mentioned above, then cause the density unevenness of developer solution on the wafer for example sometimes, it is inhomogeneous to cause developing.In addition, cause residue in the developer solution attached on the pattern of front wafer surface and produce developing defect sometimes in this part.

Be provided with cleaning solution supplying nozzle 80 in the development treatment portion 12.About U-shaped shape that cleaning solution supplying nozzle 80 is to the negative direction opening of directions X forms.Promptly, as Fig. 1 and shown in Figure 6, cleaning solution supplying nozzle 80 is made of with the vertical connecting portion 80c that the end of lower nozzle 80b couples together the carrying in the elongated lower nozzle 80b of directions X and the end with upper nozzle 80a of positive dirction one side that is positioned at the directions X of wafer W of below that carries over elongated upper nozzle 80a in directions X, is positioned at wafer W of the top that is positioned at wafer W.
As depicted in figs. 1 and 2, on the sidewall of positive dirction one side of the directions X of container handling 10, be formed with the guide rail 90 that extends to the Y direction.As cleaning solution supplying nozzle 80, for example its vertical connecting portion 80c is maintained on the nozzle arm 91.Nozzle arm 91 can move to the Y direction on guide rail 90 under the driving of drive sources such as motor 92.Cleaning solution supplying nozzle 80 under the state that wafer W is clipped in the middle, from delivery outlet 80d output cleaning fluid up and down and on the Y direction end from wafer W move to the other end, thereby can supply with cleaning fluid to the upper surface and the lower surface of wafer W.
Bottom in development treatment portion 12 is provided with the receiving vessel 100 that the liquid that falls from cleaning solution supplying nozzle 80 and wafer W is received.As shown in Figure 1, be connected with discharging tube 101 with the external communications of container handling 10 on the receiving vessel 100.
On the side of negative direction one side of the directions X of container handling 10, what be formed with supplying clean air gives gas port 110.For example be connected with the air supply pipe 112 that is communicated with air supply source 111 on the gas port 110.On near the bottom surface the end of positive dirction one side of the directions X of container handling 10, be formed with exhausr port 113.Exhausr port 113 for example is connected on the depression generator 115 by gas outlet 114.By this depression generator 115, the atmosphere gas of container handling 10 can be discharged from exhausr port 113.From giving gas port 110 supplying clean airs and discharging, just can in container handling 10, form from transfer part 11 to development treatment portion 12 airflow flowing from exhausr port 113.
In addition, more than the output of driving, nozzle 50,51,80,70 of the cleaning solution supplying nozzle 80 put down in writing or ejection start-stop, give the start-stop etc. of the exhaust of giving gas and exhausr port 113 of gas port 110, C controls by control part.
Below, just the process of developing with the development processing apparatus 1 that as above constitutes describes.
For example when carrying out development treatment, be all the time from carrying out carrying out exhaust for gas port 110 to gas with from exhausr port 113, container handling 10 in, form from the air-flow of transfer part 11 to the mobile cleaning of development treatment portion 12.In addition, for example blow out nozzle 51 blow out air, between nozzle maintaining part 40,41, form air curtain from air.
And, at first utilize outside conveying arm that wafer W is sent in the transfer part 11 from delivery port 20, and support with supporting pin 22 as shown in Figure 1.After wafer W is supported on the supporting pin 22, to wafer W one side shifting, and carry out clamping with the lateral surface of the both sides of the Y direction of 35 pairs of wafer W of clamping limb as shown in Figure 2 at the clamping limb 35 of the both sides of Y direction standby.Secondly, by clamping limb 35 wafer W is moved horizontally to the positive dirction of the directions X of development treatment portion 12 1 sides.And be about to begin from developer solution supply nozzle 50 output developer solutions before pass through between the nozzle maintaining part 40,41 in wafer W, wafer W is passed through from the below of the developer solution exported.That is, the developer solution supply nozzle 50 of output developer solution relatively moves with respect to wafer W from the end to end of wafer W.So, will on the front of wafer W, form the liquid film of developer solution.Along with the supply of developer solution, the development of wafer W just begins.
Wafer W stops after for example moving to the central part of development treatment portion 12 always.Afterwards, wafer W is carried out the static development of given time under the state that is held arm 35 clampings.Through behind the given time, output cleaning fluid limit, cleaning solution supplying nozzle 80 limits end from wafer W on the Y direction moves to the other end.For example cleaning solution supplying nozzle 80 repeatedly moves back and forth between the two ends of wafer W.So the developer solution in the front of wafer W is replaced as cleaning fluid, on wafer W, form the liquid film (liquid layer) of cleaning fluid.Along with the supply of this cleaning fluid, the development of wafer W just stops.
After the front of wafer W forms the liquid layer of cleaning fluid, wafer W is moved to the negative direction of the directions X of transfer part 11 1 sides by clamping limb 35.Be about to before pass through between the nozzle maintaining part 40,41 in wafer W, blow out nozzle 70 ejection air from the air of below.In addition, increase the air mass flow that blows out nozzle 51 ejections from the air of top.Wafer W is passed through from the air that upper and lower blows from this, removes with the liquid layer of the cleaning fluid in the front of wafer W with attached to the liquid at the back side of wafer W.At this moment, as shown in Figure 7, the air that air blows out nozzle 51 forms " air doctor blade ", utilize the pressure of air once to remove totally towards the other end cleaning fluid R in the front of wafer W from an end of wafer W, drying makes it to become.In addition, even be arranged on a small quantity also and can prevent that then mist is splashed in the transfer part 11 to development treatment portion 12 1 air that blows side out if air is blown out nozzle 51.It also is same blowing out nozzle 70 for air.
Stop in the time of above the supporting pin 22 of wafer W in moving to transfer part 11, from clamping limb 35, transfer on the supporting pin 22, be supported on the supporting pin 22.Afterwards, the conveying arm by the outside takes out wafer W a series of development treatment end from delivery port 20.This a series of development treatment, for example be by control part C to the start-stop of the output of the driving of conveying mechanism 13 and cleaning solution supplying nozzle 80, each nozzle or ejection, control for the start-stop etc. of the exhaust of giving gas and exhausr port 113 of gas port 110 to realize.
According to above embodiment, owing in container handling 10, be provided with conveying mechanism 13, thereby can carry out clamping with the lateral surface of 35 pairs of wafer W of clamping limb, and between transfer part 11 and development treatment portion 12, carry.Therefore, not as before treating fluid form throughout and pollute and can suppress to produce in the container handling 10 particulates.
In addition, owing in the development treatment portion 12 of container handling 10, be provided with the cleaning solution supplying nozzle 80 that can move to the Y direction, therefore, can make cleaning solution supplying nozzle 80 move to the other end from an end of wafer W, developer solution on the wafer W is replaced as cleaning fluid, on wafer W, forms the liquid layer of cleaning fluid.
Because cleaning solution supplying nozzle 80 takes the shape of the letter U formation approximately and can supply with cleaning fluid to the front and back of wafer W, thereby can also clean the back side of wafer W.
Owing between transfer part 11 and development treatment portion 12, be provided with air and blow out nozzle 51, thus can wafer W from development treatment portion 12 when transfer part 11 moves, the cleaning fluid on the wafer W is removed, drying makes it to become.Therefore, the liquid that can not that is attached on the wafer W in development treatment portion 12 1 sides enters transfer part 11, can keep the cleaning of transfer part 11.Its result for example is admitted on the wafer W of transfer part 11 and can be attached with particulate, and wafer W can be developed well.
Blow out nozzle 51 by air, between transfer part 11 and development treatment portion 12, form air curtain.Thus, the mist that can avoid swimming in development treatment portion 12 enters transfer part 11.
Owing to below container handling 10, also be provided with air and blow out nozzle 70, thereby the liquid attached to the back side of wafer W can also be removed.
Owing to form to gas port 110, form exhausr port 113 in development treatment portion 12 1 sides in transfer part 11 1 sides, thereby in container handling 10, form air-flow from transfer part 11 1 side direction development treatment portions 12 1 side flow, therefore, can avoid the dirts such as mist of development treatment portion 12 1 sides to enter transfer part 11 1 sides.Its result, the wafer W that is admitted in the transfer part 11 can not polluted, and development can be carried out well.
Owing between the clamping limb 35 of conveying mechanism 13 and the 2nd slide block 34, be provided with spring 36, thereby the impact can cushion clamping limb 35 and contact with the lateral surface of wafer W the time.In addition, even the location deviation a little of the wafer W on the supporting pin 22 also can gently be resolved.
Owing at the rear of clamping limb 35 fixed part 37 is set, and fixed part 37 is linked to each other by spring 38 with clamping limb 35, therefore, it is certain that the contact pressure in the time of can making clamping limb 35 holding chip W keeps.
Be the circular arc indent because the front end face 35a of clamping limb 35 is seen from the side over, therefore,, also can make clamping limb 35 align the wafer W channeling conduct with the center of the thickness direction of wafer W even if the height of clamping limb 35 and wafer W has deviation slightly.Its result can prevent that wafer W from dropping from clamping limb 35 in course of conveying.
In addition,, utilize again owing to form the liquid layer of cleaning fluid in the front of wafer W " air doctor blade " liquid layer of this cleaning fluid is removed to the other end from an end of wafer W, therefore, can bring under the state in the cleaning fluid its removal at the residue of the generation of will developing.Its result can not prevent to produce developing defect because of this adhering to residue attached on the wafer W.
In the above embodiment, cleaning solution supplying nozzle 80 is arranged in the development treatment portion 12, but also can be arranged between transfer part 11 and the development treatment portion 12.In this occasion, can be as shown in Figure 8 blow out cleaning solution supplying nozzle 120 is set between the nozzle 51 at the developer solution supply nozzle 50 of nozzle maintaining part 40 and air.Cleaning solution supplying nozzle 120 forms across the two ends of the length direction (Y direction) of nozzle maintaining part 40 equally with developer solution supply nozzle 50 for example as shown in Figure 9.Be formed with the delivery outlet 120a of a plurality of circular holes that are arranged in a row in the longitudinal direction on the cleaning solution supplying nozzle 120.For example as shown in Figure 8, be connected with the cleaning solution supplying pipe 122 that is communicated with cleaning solution supplying source 121 on the nozzle maintaining part 40.Cleaning solution supplying nozzle 120 can will be exported downwards from delivery outlet 120a from cleaning solution supplying source 121 through cleaning solution supplying pipe 122 cleaning liquid supplied.
In addition, be provided with cleaning solution supplying nozzle 130 too on the nozzle maintaining part 41 of below.Cleaning solution supplying nozzle 130 is provided with opposite to each other with cleaning solution supplying nozzle 120.Cleaning solution supplying nozzle 130 has the formation same with cleaning solution supplying nozzle 120, can will export upward from delivery outlet from cleaning solution supplying source 131 through cleaning solution supplying pipe 132 cleaning liquid supplied.
The wafer W that finishes in the static development of given time moves to the negative direction of the directions X of transfer part 11 1 sides, wafer W between nozzle maintaining part 40,41 by the time, from cleaning solution supplying nozzle 120 and cleaning solution supplying nozzle 130 output cleaning fluids.At this moment, stop to blow out nozzle 51,70 ejection air from air.In addition, for example wafer W between the nozzle maintaining part 40,41 after negative direction one side of directions X is passed through fully, wafer W this time will move to the positive dirction of the directions X of development treatment portion 12 1 sides, passes through once more between the cleaning solution supplying nozzle 120 of exporting cleaning fluid and cleaning solution supplying nozzle 130.This moves back and forth and can repeatedly carry out.So, will on the front of wafer W, form the liquid layer of cleaning fluid.And the dirt at the back side of wafer W is removed.And the wafer W that finally arrives development treatment portion 12 1 sides moves to the negative direction of the directions X of transfer part 11 1 sides.At this moment, cleaning solution supplying nozzle 120 and 130 stops to export cleaning fluid, blows out nozzle 51,70 blow out air and replace from air, forms " air doctor blade ".Like this, will be same with above-mentioned embodiment, the front of wafer W and the cleaning fluid at the back side can be removed, make it to become dry.
In above example, can carry out carrying out under the state of clamping the development treatment of wafer W equally at the lateral surface of 35 pairs of wafer W of clamping limb, therefore, compare with existing rolling mode of movement, can suppress the generation of the particulate in the container handling 10.In addition, do not move, thereby the pipe arrangement formation of this supply system is simplified because the supply of developer solution, cleaning fluid and air system is connected on the nozzle maintaining part 40,41.
In above-mentioned example, be with cleaning solution supplying nozzle 120,130 be arranged on wafer W transport path up and down, but also can only have the cleaning solution supplying nozzle 120 of top.In addition, air blow out nozzle 51,70 also can only have the top air blow out nozzle 51.
In the above embodiment, blow out nozzle 51 by air and between transfer part 11 and development treatment portion 12, form air curtain, but also the air supply unit that is intended to form air curtain can be set in addition.
In addition, also can be as shown in figure 10, see over from depression angle and above the 1st guide rail 31 of the both sides of the length direction of nozzle maintaining part 40, air to be set also and to blow out nozzle 140.So, can between two sidewalls of the Y of container handling 10 direction, form air curtain, prevent that conscientiously the atmosphere gas that is polluted by mist of development treatment portion 12 from flowing into transfer part 11.At this moment, nozzle maintaining part 40 is extended on the guide rail 31 always, make the air that is arranged on this nozzle maintaining part 40 blow out two the sidewalls formation of nozzle 51 across the Y direction of container handling 10.
Abovely be illustrated with regard to preferred forms of the present invention, but the present invention is not subjected to the qualification of above-mentioned example with reference to accompanying drawing.Obviously, as industry personnel, can also in the scope of the thought that claims are put down in writing, expect various modifications or improve example that will be understood that, these changes and improvement belong in the technical scope of the present invention certainly.
For example, in the above embodiment, developer solution supply nozzle 50, air blow out nozzle 51, cleaning solution supplying nozzle 80,120,130, air and blow out delivery outlet or the blow-off outlet that nozzle 70 has circular hole or slit-shaped respectively, but each nozzle also can have the delivery outlet or the blow-off outlet of Any shape.
Below, other embodiment is described.Figure 11 is vertically analysed and observe key diagram to what the formation summary of the related development processing apparatus of other embodiment showed, and Figure 12 is laterally analysed and observe key diagram to what the formation summary of development processing apparatus showed.The formation of the development processing apparatus 1 that this other embodiment is related is identical with main composition shown in Figure 1, and the parts of representing with identical numbering among the figure have identical formation with development processing apparatus 1.
In the present embodiment, for example be provided with the mesh plate 75 that liquid can pass through in development treatment portion 12 1 sides.As shown in figure 12, mesh plate 75 for example is the square formation with length of side bigger than the diameter of wafer W, can be with the whole covering of the upper surface of wafer W.Mesh plate 75 for example has the thickness about 0.1～3.0mm, for example has the order number about 100～300 orders (the order number of each inch).The material of mesh plate 75, what for example use is polyarylate or polyamide-based synthetic resin.Mesh plate 75 has passed through hydrophilicity-imparting treatment, is set in below 10 ° with the contact angle of developer solution.This hydrophilicity-imparting treatment both can adopt the mode that hydrophilic agent is immersed in the material of mesh plate 75 to carry out, also can adopt to mesh plate 75 carry out plasma treatment, the mode of carrying out oxidation processes afterwards carries out.In addition, if the contact angle of mesh plate 75 approach between 0 ° the detection boundaries value to 5 ° then better.
Be provided with cleaning solution supplying nozzle 80 in the development treatment portion 12.About U-shaped shape that cleaning solution supplying nozzle 80 is negative direction one side opening of directions X forms.Promptly, cleaning solution supplying nozzle 80 as shown in figure 11, by the top that is positioned at wafer W and mesh plate 75 and carry over elongated upper nozzle 80a in directions X, be positioned at the below of wafer W and mesh plate 75 and carry in the elongated lower nozzle 80b of directions X and be positioned at wafer W directions X positive dirction one side the side and the end of upper nozzle 80a constituted with the vertical connecting portion 80c that the end of lower nozzle 80b couples together.Cleaning fluid supplies to the upper surface of wafer W through mesh plate 75.
Below, just the process of developing with the development processing apparatus 1 that as above constitutes describes.
For example, when carrying out development treatment, be all the time from carrying out carrying out exhaust for gas port 110 to gas with from exhausr port 113, container handling 10 in, form from the air-flow of transfer part 11 to the mobile cleaning of development treatment portion 12.In addition, for example blow out nozzle 51 blow out air, between nozzle maintaining part 40,41, form air curtain from air.
And, at first wafer W is sent in the transfer part 11 from delivery port 20, and is supported with supporting pin 22 as shown in figure 11 by the conveying arm of outside.After wafer W was supported on the supporting pin 22, to wafer W one side shifting, and the lateral surface of the both sides of the Y direction of 35 pairs of wafer W of clamping limb carried out clamping as shown in figure 12 at the clamping limb 35 of the both sides of Y direction standby.Secondly, by clamping limb 35 wafer W is moved horizontally to the positive dirction of the directions X of development treatment portion 12 1 sides.And be about to begin from developer solution supply nozzle 50 output developer solutions before pass through between the nozzle maintaining part 40,41 in wafer W, wafer W is passed through from the below of the developer solution exported.
At this moment, shown in Figure 13 (a), from the developer solution of developer solution supply nozzle 50 output from mesh plate 75 by after supply on the front of wafer W.Shown in Figure 13 (b), the developer solution K that supplies on the wafer W is sandwiched between wafer W and the mesh plate 75, and under attached to the state on the wafer W along the lower surface of mesh plate 75 positive dirction one side shifting to directions X.Because mesh plate 75 possess hydrophilic properties, thus this moment developer solution K and mesh plate 75 between sliding resistance little, mobile be suppressed of developer solution K on wafer W.In addition, in wafer W shown in Figure 13 (c) after the below of developer solution supply nozzle 50 is passed through fully, just wafer W stops to move.At this moment, will be in and be covered with developer solution K, developer solution K on whole of front of wafer W and be filled in state between wafer W and the mesh plate 75.Developer solution K is squeezed between mesh plate 75 and the wafer W, forms the liquid film with thickness of developer solution K in the front of wafer W, and wafer W is developed.
Wafer W is carried out the static development of given time under the state that is held arm 35 clampings.Through behind the given time, output cleaning fluid limit, cleaning solution supplying nozzle 80 limits end from wafer W on the Y direction moves to the other end.For example cleaning solution supplying nozzle 80 repeatedly moves back and forth between the two ends of wafer W.For the front of wafer W, be to supply with cleaning fluids through mesh plate 75 from the upper nozzle 80a of cleaning solution supplying nozzle 80.Thus, the developer solution in the front of wafer W is replaced as cleaning fluid, on wafer W, forms the liquid film (liquid layer) of cleaning fluid.Along with the supply of this cleaning fluid, the development of wafer W just stops.
On the front of wafer W, form after the liquid layer of cleaning fluid, next wafer W is moved to the negative direction of the directions X of transfer part 11 1 sides by clamping limb 35.Be about to before pass through between the nozzle maintaining part 40,41 in wafer W, blow out nozzle 70 ejection air from the air of below.In addition, increase the air mass flow that blows out nozzle 51 ejections from the air of top.Wafer W is passed through from the air that upper and lower blows from this, removes with the liquid layer of the cleaning fluid in wafer W front with attached to the liquid at the back side of wafer W.At this moment, as above-mentioned shown in Figure 7, the air that air blows out nozzle 51 forms " air doctor blade ", utilize the pressure of air once to remove totally towards the other end cleaning fluid R in wafer W front from an end of wafer W, make it to become dry.
Stop in the time of above the supporting pin 22 of wafer W in moving to transfer part 11, from clamping limb 35, transfer on the supporting pin 22.Afterwards, the conveying arm by the outside takes out wafer W a series of development treatment end from delivery port 20.Above-mentioned a series of development treatment, for example be by control part C to the start-stop of the output of the driving of substrate carrying mechanism 13 and cleaning solution supplying nozzle 80, each nozzle or ejection, control for the start-stop etc. of the exhaust of giving gas and exhausr port 113 of gas port 110 to realize.
According to above embodiment, because there is the mesh plate 75 that passes through hydrophilicity-imparting treatment in intermediary below developer solution supply nozzle 50, thereby developer solution is good to the wetting state of mesh plate 75.Therefore, even developer solution was fed between mesh plate 75 and the wafer W when wafer W moved below mesh plate 75, the sliding resistance between developer solution on the wafer W and the mesh plate 75 is also very little, mobile be suppressed of developer solution on wafer W.Its result, the developer solution on the wafer W is stable, and the development in the front wafer surface can be stablized and do not produced spot ground and carry out.
Because mesh plate 75 is to form from the below of developer solution supply nozzle 50 towards direct of travel one side of wafer W, thereby the developer solution that supplies on the wafer W will be maintained between wafer W and the mesh plate 75.Thus, also can suppress flowing of developer solution, the stable developing ground of wafer W is carried out.
Owing to can on wafer W, supply with cleaning fluid through mesh plate 75, thereby can be at the liquid layer of the cleaning fluid of the gap respective thickness between formation and mesh plate 75 and the wafer W on the wafer W by cleaning solution supplying nozzle 80.Therefore, can supply with the cleaning fluid of q.s to wafer W, the development residue of avoiding remaining on the wafer W is attached on the pattern.In addition, can be under the state of residue being brought in the cleaning fluid, utilize air to blow out nozzle 51 " air doctor blade " cleaning fluid on the wafer W is removed.
In addition, carry out the conveying of wafer W, thereby carry and do not contact, can the back side of wafer W not polluted with the back side of wafer W with parts owing to can carry out the state of clamping with the lateral surface of 35 pairs of wafer W of clamping limb of substrate carrying mechanism 13.
Because being provided with air between transfer part 11 and development treatment portion 12 blows out nozzle 51, thereby can the cleaning fluid on the wafer W be removed when transfer part 11 moves from development treatment portion 12, make it to become dry in wafer W.Therefore, 12 1 sides enter transfer part 11 attached to the liquid that can not on the wafer W in development treatment portion, can keep the cleaning of transfer part 11.Its result, for example impurity can not be attached on the wafer W that is admitted in the transfer part 11, and wafer W can be developed well.
In the above embodiment, cleaning solution supplying nozzle 80 is arranged in the development treatment portion 12, but also can be arranged between transfer part 11 and the development treatment portion 12.In this occasion, can be as shown in figure 14 blow out cleaning solution supplying nozzle 120 is set between the nozzle 51 at the developer solution supply nozzle 50 of nozzle maintaining part 40 and air.In addition, for example as shown in figure 14, be connected with the cleaning solution supplying pipe 122 that is communicated with cleaning solution supplying source 121 on the nozzle maintaining part 40.Cleaning solution supplying nozzle 120 can will be exported downwards from delivery outlet 120a from cleaning solution supplying source 121 through cleaning solution supplying pipe 122 cleaning liquid supplied.In addition, mesh plate 75 both can cover the delivery outlet 120a that also can not cover cleaning solution supplying nozzle 120.
The processing procedure of the wafer W after the static development of given time finishes is identical with the example of prior figures 8.
In above example, do not move because the supply of developer solution, cleaning fluid and air system is connected on the nozzle maintaining part 40,41, thereby the pipe arrangement formation of this supply system is simplified.
In the above-described embodiment, cleaning solution supplying nozzle 120 is arranged between transfer part 11 and the development treatment portion 12, but also can be adjacent to be provided with at positive dirction one side and the mesh plate 75 of the directions X of mesh plate 75.Figure 15 illustrates an one example.For example, the length of the directions X of mesh plate 75 is shorter, forms with for example short than the diameter of wafer W length.Again for example, mesh plate 75 forms with half length of the diameter of for example wafer W.
In positive dirction one side of the directions X of mesh plate 75, above-mentioned cleaning solution supplying nozzle 120 is to be provided with near mesh plate 75.Distance on from the outgoing position of developer solution supply nozzle 50 to the directions X of the outgoing position of cleaning solution supplying nozzle 120 is shorter than the diameter of wafer W, for example is half of diameter of wafer W.Cleaning solution supplying nozzle 120 for example is maintained on the nozzle maintaining part 135 of the end face that is fixed on container handling 10.In addition, below cleaning solution supplying nozzle 120, similarly be provided with cleaning solution supplying nozzle 130 with above-mentioned embodiment.Cleaning solution supplying nozzle 130 is maintained on the nozzle maintaining part 136.Substrate carrying mechanism 13 can make wafer W pass through along mesh plate 75 below mesh plate 75, passes through from the below of the delivery outlet 120a of cleaning solution supplying nozzle 120 again.
In addition, same when carrying out development treatment with above-mentioned embodiment, the wafer W of transfer part 11 is carried to the positive dirction of the directions X of development treatment portion 12 1 sides with conveying mechanism 13.At this moment, shown in Figure 16 (a), supply with developer solution K through mesh plate 75 to the front of wafer W from developer solution supply nozzle 50.Wafer W is passed through below mesh plate 75 when the liquid layer of developer solution K forms, carries out the development of wafer W during this period.Secondly, shown in Figure 16 (b),, after wafer W is just exposed below the mesh plate 75, supply with cleaning fluid A to it from cleaning solution supplying nozzle 120 output cleaning fluid A.Along with the supply of this cleaning fluid A, developing just stops.As mentioned above, during supplying with developer solution K and supply with before the cleaning fluid A from developer solution supply nozzle 50, be the development time of wafer W to the cleaning solution supplying nozzle 120 of positive dirction one side of the directions X that is positioned at mesh plate 75.This development time can be controlled by the wafer W transporting velocity of adjusting conveying mechanism 13.
After wafer W was passed through from the below of cleaning solution supplying nozzle 120 shown in Figure 16 (c), cleaning fluid A covered on the whole front of wafer W, and whole development of wafer W stops.At this moment, form the liquid layer of cleaning fluid A in the front of wafer W.In addition, in the process that wafer W is passed through, also, the back side of wafer W is also cleaned from cleaning solution supplying nozzle 130 output cleaning fluids.
After forming the liquid layer of cleaning fluid on the wafer W, wafer W moves to the negative direction of the directions X of transfer part 11 1 sides, and the air that blows out nozzle 51,70 from air makes wafer W become dry.
According to this example,, thereby the development in the front wafer surface is carried out equably because to play time of supplying with before the cleaning fluid all be certain for any point of front wafer surface from supplying with developer solution.In addition, adjust by transporting velocity, very simply the development time of control wafer W the wafer W of conveying mechanism 13.
The cleaning solution supplying nozzle 120 that above-mentioned embodiment is put down in writing also can be as shown in figure 17, its delivery outlet 120a towards with the oblique below of mesh plate 75 opposite sides.Design like this can prevent that cleaning fluid from entering in the mesh plate 75 and pollute mesh plate 75.
In the above embodiment, mesh plate 75 is provided with regularly, but also can be designed to be able to move along with moving of wafer W.
Figure 18 illustrates an one example.As shown in figure 18, be provided with the mesh plate conveying mechanism 150 that mesh plate 75 is kept and carries in the container handling 10.As shown in figure 19, mesh plate conveying mechanism 150 can be transported to the transport path that is higher than conveying mechanism 13 transfer wafers with mesh plate 75 and is lower than on the position of developer solution supply nozzle 50 to directions X.
Mesh plate conveying mechanism 150 for example as shown in figure 18, the foreign side of each guide rail 31 in container handling 10 has and is parallel to the guide rail 151 that guide rail 31 extends from transfer part 11 to development treatment portion 12.Each guide rail 151 is provided with slide block 152.Slide block 152 for example has drive sources such as motor, can move to directions X along guide rail 151.
On each slide block 152, the keeping arm 153 that the end to Y direction one side of mesh plate 75 keeps is installed.
In the present embodiment, mesh plate conveying mechanism 150 is made of guide rail 151, slide block 152 and keeping arm 153.By this mesh plate conveying mechanism 150, keeping arm that mesh plate 75 is kept 153 is moved to directions X, between transfer part 11 and development treatment portion 12, carry out the conveying of mesh plate 75.And the control of the action of mesh plate conveying mechanism 150 is undertaken by control part C.
In addition, when carrying out development treatment, at first, wafer W is sent in the container handling 10 from the outside, after wafer W is supported on the supporting pin 22, mesh plate 75 will be positioned at the top of wafer W.At this moment, see over from depression angle, mesh plate 75 covers the entire upper surface of wafer W.Afterwards, same with above-mentioned embodiment, when being transferred mechanism 13, wafer W makes when being transplanted on development treatment portion 12 1 sides, and mesh plate 75 also is transplanted on development treatment portion 12 1 sides by mesh plate conveying mechanism 150.At this moment, mesh plate 75 moves with the speed identical with wafer W, keeps the state with the upper surface covering of wafer W.
Before wafer W was passed through below the developer solution supply nozzle 50, the output of developer solution began, when wafer W as shown in figure 20 from the below of developer solution supply nozzle 50 by the time, developer solution K supplies on the wafer W through mesh plate 75.Supplying to developer solution K on the wafer W is sandwiched between mesh plate 75 and the wafer W and is filled in wherein.At this moment, since same with above-mentioned embodiment, the good hydrophilic property of mesh plate 75, thereby the sliding resistance between mesh plate 75 and the developer solution K is little, mobile be suppressed of developer solution on wafer W.After wafer W and mesh plate 75 passed through below the developer solution supply nozzle 50 fully, developer solution K covered on whole of front of wafer W.
Wafer W after passing through from the below of developer solution supply nozzle 50 and mesh plate 75 are seen over and are stopped in the position that liquid supply nozzle 80 is clipped in the middle that is cleaned of development treatment portion 12 1 sides as shown in figure 19 from the side.Wafer W is carried out the static development of given time under this state.In case static development finishes, and is same with above-mentioned embodiment, output cleaning fluid limit, cleaning solution supplying nozzle 80 limits moves to the other end to the Y direction from an end of wafer W, forms the liquid layer of cleaning fluid in the front of wafer W.
Afterwards, for example as shown in figure 21, only wafer W moves to the negative direction of the directions X of transfer part 11 1 sides, and same with above-mentioned embodiment, is used to blow out from air that the air of nozzle 51 forms " air doctor blade " liquid layer of the cleaning fluid in wafer W front is removed.In addition, for the back side of wafer W, the air that also is used to blow out from air nozzle 70 is removed liquid.
Stop in the time of above the supporting pin 22 of wafer W in moving to transfer part 11, be transferred on the supporting pin 22.Afterwards, the conveying arm by the outside takes out wafer W from delivery port 20.
According to this example, between wafer W that moves and developer solution supply nozzle 50, have mesh plate 75 too, thereby developer solution is good to the wetting state of mesh plate 75 through hydrophilicity-imparting treatment.Therefore, even supply with developer solution when wafer W moves, the sliding resistance between developer solution on the wafer W and the mesh plate 75 is little, mobile be suppressed of developer solution on wafer W.Its result, the developer solution on the wafer W is stable, and the development in the front wafer surface can be stablized and do not produced spot ground and carry out.
In addition, making mesh plate 75 in the above-mentioned example that wafer W moves, also can as described above cleaning solution supplying nozzle 80 be arranged between transfer part 11 and the development treatment portion 12.
