Several embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided for the purpose of making the disclosure of the present application more thorough and comprehensive.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. 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. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0034] Embodiment One
[0035] Please refer to Figures 1-4 The first embodiment of the present application provides a pose adjustment device for wafer measurement, which is arranged in a wafer measurement device, and the wafer measurement device includes a device main body 10 and a lens group unit (not shown in the figure) arranged in the device main body 10 for imaging detection of a target wafer 30.
[0036] When the device detects the target wafer 30, the target wafer 30 needs to be clamped and fixed by the pre-set semi-closed jig 20 in the device, and then the pose adjustment of the semi-closed jig 20, i.e. the position and attitude, including the adjustment of multiple degrees of freedom in XYZ direction, etc. is performed to change the relative position of the target wafer 30 between the device main body 10 and the lens group unit through the driving of the semi-closed jig 20, so that the distance and angle between the target wafer 30 and the lens group unit can be finely adjusted, the pose of the target wafer 30 in the device main body 10 is changed, and thus the imaging accuracy of the lens group unit and the overall detection efficiency can be improved.
[0037] First of all, it is explained that the target wafer 30 is an additional object loaded on the semi-closed jig 20, and the function of the device includes the pose adjustment of the target wafer 30, but in fact, the pose adjustment of the semi-closed jig 20 is performed, and the target wafer 30 moves with the semi-closed jig 20 to realize the pose adjustment of the target wafer 30. In order to facilitate the explanation, the effect of adjusting the semi-closed jig 20 and the target wafer 30 is collectively referred to as adjusting the target wafer 30.
[0038] In the embodiment, the device comprises a first supporting mechanism 40 for reference point positioning of the semi-enclosed jig 20 and the target wafer 30 fixed thereby, a second supporting mechanism 50 for adjustment of the semi-enclosed jig 20 and the target wafer 30 fixed thereby, and a third supporting mechanism 60 for adjustment of the semi-enclosed jig 20 and the target wafer 30 fixed thereby. The first supporting mechanism 40, the second supporting mechanism 50 and the third supporting mechanism 60 are used to position, support and adjust the target wafer 30, so that the position of the target wafer 30 in the device main body 10 can be adjusted.
[0039] Specifically, the semi-enclosed jig 20 is provided with an opening on at least one side, forming a C-shaped structure, or a semi-enclosed ring structure or a ring-like structure. The first position 20a and the second position 20b on both sides of the opening of the semi-enclosed jig 20 are respectively provided with the first positioning member 21 and the second positioning member 22, and the third position 20c of the semi-enclosed jig 20 away from the first positioning member 21 and the second positioning member 22 is provided with the third positioning member 23.
[0040] In the embodiment, the first positioning member 21, the second positioning member 22 and the third positioning member 23 are respectively matched with the first supporting mechanism 40, the second supporting mechanism 50 and the third supporting mechanism 60, so as to realize the position adjustment of the target wafer 30.
[0041] More specifically:
[0042] In the first supporting mechanism 40, the first V-shaped structure 41 is provided on the device main body 10, and a first V-shaped groove (not shown in the figure) is formed on the top surface thereof, used for positioning and supporting the first positioning member 21 at the first position 20a of the opening of the semi-enclosed jig 20. Specifically, the first V-shaped groove on the top surface is used for positioning and supporting the first positioning member 21.
[0043] Moreover, the position of the first V-shaped structure 41 on the device main body 10 is fixed, and the first positioning member 21 abuts against the first V-shaped groove. In the embodiment, since the position of the first V-shaped structure 41 is constant, it can be used as a reference point for the position adjustment of the semi-enclosed jig 20 and the target wafer 30, and all adjustments of the semi-enclosed jig 20 and the target wafer 30 are based on the reference point.
[0044] In the second supporting mechanism 50, the first guide member 51 and the second V-shaped structure 52 slidingly arranged in the first guide member 51 are included, and the second V-shaped structure 52 is used for positioning and supporting the second positioning member 22 at the second position 20b of the semi-enclosed jig 20.
[0045] Unlike the first support mechanism 40 described above, the second support mechanism 50 also includes a first adjustment component 53 for adjusting the first guide member 51 and a second adjustment component 54 for adjusting the second V-shaped structural member 52.
[0046] More specifically, the first guide member 51 is slidably connected to the main body 10 of the device, while the first adjustment component 53 is fixed by an additional support block. By rotating the first knob in the first adjustment component 53, for example by using a motor drive, the first guide member 51 moves along the Y direction, thereby driving the second V-shaped structural member 52 to move along the Y direction, including the Y+ direction and the Y- direction.
[0047] In addition, the second adjustment component 54 directly acts on the second V-shaped structural member 52 arranged along the X direction on the first guide member 51. By rotating the second knob in the second adjustment component 54, the second V-shaped structural member 52 can also be driven by a motor to move along the X direction on the first guide member 51, including the X+ direction and the X- direction.
[0048] In the above, the first adjustment component 53 and the second adjustment component 54 drive the second V-shaped structure 52 to move along the Y and X directions respectively. Finally, the second positioning component 22, which abuts against the second V-shaped groove 52a on the second V-shaped structure 52, drives the semi-enclosed fixture 20 to swing, including swinging in the Y and X directions, so that the target wafer 30 swings along the Y and X directions with the reference point as the origin.
[0049] In addition, a reset through hole 51a is provided in the first guide member 51 along the X direction. For example, two reset through holes 51a are symmetrically arranged on both sides of the second V-shaped structure 52 in the first guide member 51. An elastic member (not shown in the figure) is provided in the reset through hole 51a. One end of the elastic member is fixed in the reset through hole 51a, that is, fixedly connected to the second V-shaped structure 52, while the other end passes through the reset through hole 51a towards the second adjustment component 54 and is connected to the flange on the second V-shaped structure 52, so that the elastic member is connected between the first guide member 51 and the second V-shaped structure 52, so that the second V-shaped structure 52 always has a tendency to move towards the first guide member 51.
[0050] Since the second V-shaped structural member 52 and the second positioning member 22 cooperate only through the open second V-shaped groove 52a, the second adjustment component 54 can only make the second positioning member 22 move towards one side, which is equivalent to pushing the second positioning member 22 to move along the X direction, for example, the X- direction. When it is necessary to move in the opposite direction, i.e., X+, by rotating the second knob in the second adjustment component 54 in the opposite direction, under the elastic force of the elastic member, the second V-shaped structural member 52 will move towards the first guide member 51 along the X+ direction, releasing the support for the second positioning member 22. Then the semi-enclosed fixture 20 and the target wafer 30 will also swing accordingly.
[0051] Or, the elastic member is a plunger, and only one end of the plunger is fixed in the reset through hole 51a of the second V-shaped structure 52, and the other end of the plunger is a free end which penetrates through the reset through hole 51a and abuts against the flange side surface of the second V-shaped structure 52.
[0052] And in the third supporting mechanism 60, it includes a second guide 61, and a third V-shaped structure 62 slidingly connected in the second guide 61, and the third V-shaped structure 62 is used for positioning and supporting the third positioning member 23 in the third position 20c of the semi-closed jig 20.
[0053] The third supporting mechanism 60 is basically the same as the second supporting mechanism 50, and it also includes a third adjusting assembly 63 used for adjusting the second guide 61, and a fourth adjusting assembly 64 used for adjusting the third V-shaped structure 62.
[0054] The second guide 61 is slidingly connected to the equipment main body 10, and the position of the third adjusting assembly 63 is fixed. By rotating the third knob of the third adjusting assembly 63, the second guide 61 drives the third V-shaped structure 62 to move along the Y direction, including the Y+ direction and the Y- direction. In addition, the fourth adjusting assembly 64 directly acts on the third V-shaped structure 62 arranged along the Z direction of the second guide 61, and by rotating the fourth knob of the fourth adjusting assembly 64, the third V-shaped structure 62 moves along the Z direction on the second guide 61, including the Z+ direction and the Z- direction.
[0055] The third V-shaped structure 62 is driven to move along the Y direction and the Z direction by the third adjusting assembly 63 and the fourth adjusting assembly 64, and finally the third positioning member 23 abutting against the third V-shaped groove 62a of the third V-shaped structure 62 drives the semi-closed jig 20 to swing, including the Y direction and the Z direction, so that the target wafer 30 swings along the Y direction and the Z direction with the reference point as the origin.
[0056] It should be noted that in the embodiment, the first positioning member 21, the second positioning member 22 and the third positioning member 23 have the same structure, and each includes a fixed part for connecting the semi-closed jig 20 and a positioning part extending outward.
[0057] The first positioning part in the first positioning member 21 is used for abutting into the first V-shaped groove on the surface of the first V-shaped structure 41, the second positioning part in the second positioning member 22 abuts into the second V-shaped groove 52a on the surface of the second V-shaped structure 52, and the third positioning part in the third positioning member 23 abuts into the third V-shaped groove 62a on the surface of the third V-shaped structure 62.
[0058] More specifically, the first fixing part, the second fixing part and the third fixing part can be fixed to the first position 20a, the second position 20b and the third position 20c of the semi-enclosed jig 20 by means of bolts or the like, and the first positioning part, the second positioning part and the third positioning part extending from the first fixing part, the second fixing part and the third fixing part are respectively abutted to the corresponding V-shaped grooves, so that the corresponding V-shaped structural members can be positioned, supported and adjusted.
[0059] The working principle of the wafer pose adjustment device shown in the embodiment is as follows:
[0060] After the target wafer 30 is fixed by the semi-enclosed jig 20, whether the pose of the target wafer 30 in the device main body 10 needs to be adjusted is determined according to the feedback of the imaging result of the lens unit. If yes, the first V-shaped structural member 41 is adjusted by the first adjustment assembly 53 based on the reference point formed by the cooperation of the first support mechanism 40 and the first positioning member 21, so that the first positioning member 21 drives the semi-enclosed jig 20 and the target wafer 30 to swing along the Y direction, and / or the first V-shaped structural member 41 is adjusted by the second adjustment assembly 54, so that the first positioning member 21 drives the semi-enclosed jig 20 and the target wafer 30 to swing along the X direction, and / or the third V-shaped structural member 62 is adjusted by the third adjustment assembly 63, so that the third positioning member 23 drives the semi-enclosed jig 20 and the target wafer 30 to swing along the Y direction, and / or the third V-shaped structural member 62 is adjusted by the fourth adjustment assembly 64, so that the third positioning member 23 drives the semi-enclosed jig 20 and the target wafer 30 to swing along the Z direction. Then, the target wafer 30 can be adjusted in the corresponding pose according to the actual imaging condition of the wafer.
