The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used in the description of the present application includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, an embodiment of the present application provides a detection apparatus, including a detection platform 200 and a pickup module; the detection platform 200 is provided with a receiving station 2001, a feeding station 2002, an adjusting station 2004 and a detection station 2005 which are arranged at intervals along a first direction, and the receiving station 2001, the feeding station 2002, the adjusting station 2004 and the detection station 2005 jointly define a first flow path; wherein the detection station 2005 is divided into a ballast sub-station 2051 (shown in fig. 13), a first detection sub-station 2052 (shown in fig. 13) and a second detection sub-station 2053 (shown in fig. 13) which are distributed at intervals along the second direction, the ballast sub-station 2051, the first detection sub-station 2052 and the second detection sub-station 2053 jointly define a second flow path, and the ballast sub-station 2051 is located at the intersection of the second flow path and the first flow path; the first direction and the second direction are arranged at an angle.
The first direction is used as a horizontal transverse direction, the second direction is used as a horizontal longitudinal direction, and the first direction is perpendicular to the second direction. Thus, the first flow path is in the horizontal transverse direction and the second flow path is in the horizontal longitudinal direction.
Specifically, after the semiconductor element to be detected is transferred to the feeding station 2002, the first pick-up module 61 can drive the semiconductor element to be carried to the adjusting station 2004 so as to adjust and compensate the position of the semiconductor element, thereby meeting the requirement of detecting the position; the first pick-up module 61 then drives the adjusted semiconductor device to move to the inspection station 2005 for defect inspection of the semiconductor device. In the inspection, the semiconductor element is first placed in the ballast station 2051, and is driven to move along the second flow path by the ballast station 2051, and then the defect inspection is performed by the first inspection station 2052 and the second inspection station 2053. After the inspection, the first pick-up module 61 again drives the semiconductor device to be carried from the ballast station 2051 to the material receiving station 2001 for storage.
Because of the precision requirements of semiconductor elements, dust-free paper needs to be placed between any two adjacent semiconductor elements that are stacked to improve the protection. Thus, the pick-up module comprises a first pick-up module 61 and a second pick-up module 62, the first pick-up module 61 being capable of flowing along a first flow path between the feeding station 2002, the adjusting station 2004, the detecting station 2005 and the receiving station 2001; the second pick-up module 62 can circulate along the first circulation path relative to the receiving station 2001; the second pick-up module 62 is capable of picking up the dust-free paper before the semiconductor device is transferred to the receiving station 2001, and moving the dust-free paper to the receiving station 2001.
The second pick-up module 62 may pick up the dust-free paper from the feeding station 2002 or from another position, as long as it can ensure that the dust-free paper is placed between any two adjacent semiconductor elements at the receiving station 2001.
As can be seen from the foregoing, the detection device provided in this embodiment, through the angled arrangement of the first flow path and the second flow path, is equivalent to transferring a part of space along the horizontal transverse direction to the horizontal longitudinal direction while satisfying the defect detection of the semiconductor element, so as to reduce the space occupied by the detection device along the horizontal transverse direction. Thus, when the first pick-up module 61 moves along the first flow path, the moving stroke is reduced, and the use stability of the first pick-up module 61 is improved. Meanwhile, the whole detection process is divided into two moving strokes by utilizing the cooperation of the first pickup module 61 and the second pickup module 62, so that the moving stroke of the single first pickup module 61 is further reduced.
The inspection apparatus according to the present application will be described in detail below in terms of the entire inspection process of semiconductor devices.
Referring to fig. 1 and 2, in some embodiments, a scrap station 2003 is disposed along the first flow path between the receiving station 2001 and the loading station 2002 to facilitate storage of semiconductor devices that are defective after inspection. In actual use, the detection means comprises a plurality of trays 50 arranged at intervals, at least one of the plurality of trays 50 being located at a receiving station 2001 and being referred to as receiving tray 51, at least one other being located at a waste station 2003 and being referred to as waste tray 52, and at least one further being located at a loading station 2002 and being referred to as feeding tray 53. The feeding tray 53 is used for placing semiconductor elements to be detected, the receiving tray 51 is used for placing qualified semiconductor elements after detection, and the waste tray 52 is used for placing unqualified semiconductor elements after detection.
Further, two opposite guide rails are arranged at the positions of the material receiving station 2001, the material feeding station 2002 and the waste material station 2003 at intervals so as to facilitate the corresponding material trays 50 to slide in or slide out along the corresponding guide rails; meanwhile, a handle is arranged at the tail of each tray 50, so that the trays 50 can be replaced manually.
Still further, each tray 50 is configured with a relief hole 501. The detecting device further comprises a positioning piece 54, a part of the positioning piece 54 can penetrate through the avoiding hole 501 to extend into the tray 50, and the positioning piece 54 can push the semiconductor element to move in the tray 50 under the action of external force driving so as to ensure that the semiconductor element is in place. Specifically, each tray 50 is rectangular, and at least one long side and at least one short side are provided with avoiding holes 501, and the avoiding holes 501 penetrate along the depth of the tray 50. The positioning member 54 is installed at the bottom of the tray 50 and partially extends from the escape hole 501 from bottom to top to satisfy the positioning of the semiconductor device. The positioning piece 54 can be lifted up and down in the vertical direction and can be linearly moved in the horizontal direction so as to meet the positioning of semiconductor elements of different specifications. Wherein the movement of the positioning member 54 is mainly achieved by a linear cylinder drive.
As shown in fig. 1, in some embodiments, a supporting beam 120 with a length extending along the first direction is further disposed on the inspection platform 200, and the first pick-up module 61 and the second pick-up module 62 are disposed at intervals and are both slidingly connected to the supporting beam 120, and can both move along the length direction (i.e. the first direction) of the supporting beam 120, so as to meet the handling of the semiconductor element and the dust-free paper. To avoid interference between the two handling operations, the first pick-up module 61 is disposed close to the feeding tray 53, and the second pick-up module 62 is disposed close to the receiving tray 51.
It should be noted that the structure of the supporting beam 120 is a mature technology, and is not an improvement point of the present application, so that the description is omitted.
Because the thickness of the semiconductor element to be absorbed is small and the overall size is large, special attention is paid to stability in the process of carrying, so that the semiconductor element is prevented from falling off in the process of carrying, and the protection of the semiconductor element is improved. Based on this, as shown in fig. 1 and 3, in some embodiments, the first pick-up module 61 includes a static platform frame 611, a voltage amplifier 612 and a static platform 613, the static platform frame 611 is slidably connected to the supporting beam 120, the static platform 613 is mounted on the static platform frame 611, and the static platform 613 is electrically connected to the voltage amplifier 612, and the voltage amplifier 612 can regulate the static voltage of the static platform 613.
That is, the electrostatic adsorption method is used to convey the semiconductor device. Since the projection area of the electrostatic stage 613 in the vertical direction is large, it can be substantially adapted to the size of the semiconductor element; therefore, the semiconductor element can form an entire contact state with the semiconductor element during adsorption, and the contact area between the semiconductor element and the semiconductor element is increased, so that stable adsorption of the semiconductor element is met, and the falling risk is prevented.
Further, since the semiconductor element and the dust-free paper are placed across each other, a paper ejection cylinder 614 is also mounted on the electrostatic stage frame 611, and the driving end of the paper ejection cylinder 614 can pass through the electrostatic stage 613 to press against the dust-free paper, so as to prevent the dust-free paper located in the collecting tray 51 from adhering to the semiconductor element or the electrostatic stage 613. Wherein, the electrostatic platform 613 is correspondingly provided with a through hole for the driving end of the paper ejection cylinder 614 to pass through, and the position of the through hole is matched with the position of the paper ejection cylinder 614; a gap is formed between the electrostatic stage frame 611 and the electrostatic stage 613 on the side facing away from the suction side. When the drive end of the top paper cylinder 614 does not need to press against the dust-free paper, it can retract within the gap or be flush with the electrostatic stage 613. The projection surface dimension of the electrostatic stage 613 in the vertical direction is larger than the planar dimension of the semiconductor element. In this way, the suction with the entire surface of the semiconductor element is ensured, and the suction is formed with the operation of the top paper cylinder 614. Wherein the number of top paper cylinders 614 is plural and spaced apart.
Meanwhile, because the dust-free paper is used for protecting the semiconductor element, the plane size of the dust-free paper is larger than that of the semiconductor element, so that the dust-free paper is not easy to transport, and the risk of a tray exists more easily. Based on this, as shown in fig. 1 and 4, the second pick-up module 62 includes an adsorption frame 621, a plurality of adsorption members 622, and a power source, the adsorption frame 621 is slidably connected to the support beam 120, and the plurality of adsorption members 622 are arranged at intervals on the adsorption frame 621 and are connected to the power source. Wherein, the power source is the structure that is used for realizing negative pressure vacuum.
Thus, the plurality of adsorbing members 622 are arranged at intervals to meet the requirement of a larger adsorption area, and the plurality of adsorbing members 622 are fixed at multiple points, so that the adsorption effect on the dust-free paper is improved on the basis of meeting the planar size of the dust-free paper. In one embodiment, the adsorbing member 622 employs a Bernoulli chuck to perform the adsorption of the dust-free paper in a non-contact manner, thereby facilitating the soft grasping of the dust-free paper and minimizing the contact with the dust-free paper.
The specific working principle of the Bernoulli sucker is the prior art, and the Bernoulli sucker does not belong to the application point of the application, so that the Bernoulli sucker is not repeated.
In summary, as shown in fig. 3 and 4, the first pick-up module 61 and the second pick-up module 62 need to be lifted in the vertical direction to satisfy the suction operation of the electrostatic stage 613 and the suction member 622. Therefore, the first pick-up module 61 and the second pick-up module 62 each have a lifting mechanism 63, which is a first lifting mechanism and a second lifting mechanism, and the two lifting mechanisms 63 adopt a linear cylinder or other linear driving modules to connect with the corresponding electrostatic stage frame 611 or the adsorption frame 621 through the follow-up sliding block.

In actual use, the second flow path is close to the intersection with the first flow path and is the start end of the second flow path, and the other end is the end. When the first pick-up module 61 drives the semiconductor device to be placed on the test carrier 210, the test carrier 210 is located at the start end. At this time, in order to avoid interference between the capping mechanism 40 and the first pick-up module 61, the capping mechanism 40 is located at the termination end of the second flow path under the action of the first linear module 31. After the semiconductor device is cleaned on the upper surface, the capping mechanism 40 moves to the starting end under the action of the first linear module 31, and the capping carrier 41 is located above the detecting carrier 210. In order to satisfy the movement of the detection carrier 210 under the action of the first linear module 31, the detection carrier 210 needs to be connected with the slider on the first linear module 31.
Therefore, as shown in fig. 10-12, the slider of the first linear module 31 is provided with a first toothed plate 312 and a link driving mechanism 313 connected to the first toothed plate 312, the detection carrier 210 is connected with a second toothed plate 331, and the link driving mechanism 313 can drive the first toothed plate 312 to move along the first direction so as to be engaged with the second toothed plate 331 for locking or disengaged from the second toothed plate 331. When the first toothed plate 312 and the second toothed plate 331 are engaged and locked, the detection carrier 210 can move along the second direction under the action of the first linear module 31 and gradually drive into the detection areas of the first detection module 101 and the second detection module 102.

The piston rod of the toothed plate cylinder 3131 stretches and contracts along the second direction to drive the connecting block 3132 to reciprocate along the second direction, and the connecting block 3132 drives the pushing plate 3134 to reciprocate along the first direction through the connecting rod 3133 so as to meet the engagement locking or release unlocking of the first toothed plate 312 and the second toothed plate 331. An electromagnet may be used to magnetically attract the connecting block 3132, so that the pushing plate 3134 is driven to move by the connecting rod 3133, so as to realize the movement of the first toothed plate 312 relative to the second toothed plate 331.
As shown in fig. 1, 13 and 14, in some embodiments, since the first and second inspection sub-stations 2052 and 2053 are used for performing defect inspection on the upper and lower surfaces of the semiconductor device, respectively, the first and second inspection sub-stations 2052 and 2053 are located at both sides of the inspection carrier 210 along the third direction, and the inspection platform 200 is provided with inspection windows 2010. The inspection window 2010 is a through hole formed on the inspection platform 200, so that the upper and lower surfaces of the semiconductor element located at the inspection window 2010 are fully exposed in the inspection area. Therefore, the inspection apparatus further includes a first inspection module 101 and a second inspection module 102, the first inspection module 101 is installed at the first inspection sub-station 2052, the second inspection module 102 is installed at the second inspection sub-station 2053, and the structures of the first inspection module 101 and the second inspection module 102 are substantially similar.
Taking the first detection module 101 as an example, the first detection module 101 includes a light source 11, a reflecting mirror 12, and a detection camera 13, and the detection camera 13 is configured to obtain a detection image of the semiconductor element based on reflection of the material by the reflecting mirror 12. Thus, during the detection process, the light emitted by the light source 11 can be reflected by the reflecting mirror 12, so as to change the light path transmission direction. At this time, the detection camera 13 only needs to be disposed on the light path after the change of direction. By the arrangement, the detection angle of the detection camera 13 relative to the semiconductor element is reduced, and more importantly, the distance of the detection camera 13 for acquiring the semiconductor element image is reduced, so that the occupied space of the whole detection module is reduced, interference between the detection module and other structures is reduced, and the detection definition is improved.
In actual use, when the first linear module 31 drives the semiconductor element to move along the second direction so as to pass through the first detection module 101 and the second detection module 102, the position sensor on the second flow path is triggered in sequence, the signal processing center obtains the moving speed and position of the semiconductor element according to the grating ruler signal installed on the detection platform 200, the moving signal is sent to the image acquisition card after integration, and the detection camera 13 scans images at a specific frequency and line number. All the patterns are processed by the image card to form a complete product image, and the complete product image is sent to vision detection software for defect analysis. In order to meet the requirement of more comprehensive detection data, the semiconductor element is subjected to scanning detection on a second flow path entering and exiting the detection area, and when entering the detection area along the second flow path for the first time, the capping mechanism 40 is pressed above the semiconductor element and is not in direct contact with a product, so that defects such as warping, deformation and wire breakage of the semiconductor element can be effectively detected through the scanning structure. The second inspection is performed while the semiconductor element is returned along the second flow path, and the capping carrier 41 in the capping mechanism 40 is moved down to press the semiconductor element before entering the inspection area. And then moves back into the detection zone. The detection section can eliminate the interference caused by the deformation of the semiconductor element, thereby effectively detecting the defects of the semiconductor element such as color change, dirt, broken line, pinholes and the like. In this way, the quality of the semiconductor element is ensured by the two detections of the reciprocal movement along the second flow path.
