Abstract
Description
Technical Field
[0001] The present invention relates to a loading device and method for a pre-treated wafer carrier, and more particularly to a loading device and method that utilizes a simple mechanism and operation to stack and assemble a wafer ring, a wafer, and a cover, and precisely move and fix them to different positions on a carrier. Background Art
[0002] The typical integrated circuit (IC) manufacturing process can be divided into three main parts: silicon wafer fabrication, IC production, and IC packaging. After the silicon ingot is cut into wafers, they must undergo a complex process of laser treatment, crystal growth, etching, and mechanical grinding to complete the IC production. During this manufacturing process, when the wafers undergo testing, cleaning, vapor deposition, drying, or soaking in organic solvents, in order to effectively secure the wafers for processing and to simultaneously process a large number of wafers to improve processing efficiency, multiple wafers are usually fixed on a large-area carrier. This carrier simultaneously supports each wafer for processing operations mentioned above.
[0003] The basic structure of a common carrier is a large-area convex (or concave) arc-shaped disk structure. A plurality of hollow portions for accommodating wafers are provided on the carrier, and a plurality of clamps for fixing wafers are provided on the periphery of each hollow portion. When each wafer is fixed by the clamp on the top of the hollow portion (the outer convex surface of the convex arc surface or the inner concave surface of the concave arc surface), the part to be processed of each wafer can be exposed to the outside through the hollow portion. Therefore, the carrier can accommodate multiple wafers and move them to different processing procedures at the same time, so as to effectively increase the efficiency of the overall wafer processing.
[0004] As automated machining becomes increasingly popular, the use of various automatic machines to perform wafer placement operations on carriers has become an inevitable trend, saving a significant amount of manpower, reducing production costs, and improving processing efficiency. However, since wafers themselves are extremely fragile and require extremely high processing precision, not only are extremely high requirements placed on the operational accuracy of the relevant transfer mechanisms when placing and taking wafers, but when multiple transfer mechanisms are used to separately perform the assembly or stacking of wafers and related components, each transfer mechanism must also be precisely connected. Otherwise, the overall assembly accuracy and quality of the finished product can be easily affected, and even the semi-finished product can be damaged. Therefore, how to effectively calibrate each transfer mechanism so that it not only maintains excellent accuracy when a single transfer mechanism performs different object displacement actions, but also forms an excellent relative activity correlation between different transfer mechanisms to ensure the operational connection accuracy of each transfer mechanism when displacing the same object has become a major issue that all relevant industry players urgently need to work on.

Furthermore, the two jacket slides with backlight surfaces are brought into contact with each other, so that the two concave arc portions combine to form a circular hole corresponding to the wafer pre-treatment portion. The control module then drives the wafer carrier to correct its position via the wafer displacement assembly, so that the wafer is aligned to a position correctly corresponding to the center of the wafer ring;

[0054] The main advantage of the present invention is to provide a loading device and method for a pre-processed wafer carrier, wherein a wafer ring loading mechanism, a wafer loading mechanism, a cover loading mechanism and a second displacement mechanism are provided on the circumferential side of a first displacement mechanism, and a robotic arm is provided between the first displacement mechanism and the second displacement mechanism; the first displacement mechanism has a first base body that can be moved back and forth, a wafer pre-processing portion is provided on the first base body, a movable carrier is provided on the second displacement mechanism, a plurality of assembly carrying portions are provided on the carrier, and a plurality of clamps are provided on the circumference of each assembly carrying portion, an image capture component and a loading and unloading mechanism are provided on the movable end of the robotic arm; the wafer ring loading mechanism can place a wafer ring in the wafer pre-processing portion, the wafer loading mechanism places a wafer in the wafer ring, and then the cover loading mechanism places a cover in the wafer ring and overlaps the wafer An assembly is formed on the wafer, so that the peripheral side of the wafer is firmly clamped between the wafer ring and the peripheral edge of the cover, so that the wafer can maintain good flatness in the assembly. The robotic arm can drive the loading and unloading mechanism and the image capture component to correct their loading and unloading working surface and imaging surface respectively, so that the loading and unloading mechanism can positively and accurately correspond to the assembly supporting part to be assembled at a position to be assembled on the carrier. The loading and unloading mechanism can first unlock each clamp, and then move the assembly from the first base to the assembly supporting part to be assembled. Then the loading and unloading mechanism locks each clamp to fix the assembly on the assembly supporting part to be assembled, and the carrier rotates to move another assembly supporting part to the position to be assembled. With the above-mentioned simple and low-cost structure, combined with a well-planned and smooth action process, the construction cost of the equipment can be effectively reduced and the assembly efficiency can be improved.
[0055] Another advantage of the present invention is to provide a loading device and method for a pre-processed wafer carrier, wherein a plurality of distance measuring elements are provided around a loading and unloading mechanism. When the loading and unloading mechanism approaches the assembly support portion to be assembled in a direction and at an angle corresponding to a preset loading and unloading reference value, the position of the loading and unloading mechanism can be adjusted so that each distance measuring element measures an equal distance around the assembly support portion to be assembled, thereby correcting the inclination angle of the loading and unloading working surface of the loading and unloading mechanism so that the loading and unloading mechanism can correspond parallel to (have the same inclination angle) the assembly support portion to be assembled. The image capture component can approach the assembly support portion to be assembled in the same direction and inclination angle as the corrected loading and unloading working surface and directly capture an image. The position of the image capture component is then adjusted so that it accurately corresponds to the assembly support portion to be assembled, thereby correcting the position of the image capture component's imaging surface. At the same time, the position of the loading and unloading mechanism is corrected using information on the position of the corrected imaging surface so that its loading and unloading working surface can accurately and directly correspond to the assembly support portion to be assembled and its surrounding components.
[0056] Another advantage of the present invention is that it provides a loading device and method for a pre-treated wafer carrier. The top surface of the first base body is provided with a jacket slide with a backlight surface and relatively displaceable on the peripheral side of the wafer pre-treatment portion. A concave arc portion is provided on the side of each jacket slide facing the wafer pre-treatment portion, and an imaging unit is provided next to the first displacement mechanism. When the imaging unit obtains the image of the wafer moved above the wafer ring, the jacket slides can be fitted together to combine the concave arc portions into a hole with a backlight effect, so that the wafer can be easily guided to correspond to the wafer ring, so as to facilitate the subsequent operation of accurately placing the wafer into the wafer ring.

[0103] Please refer to Figure 4 As shown, the operating method of the present invention includes: a "positioning the carrier, wafer ring, wafer, and cover" procedure P1; a "wafer ring loading mechanism moves a wafer ring into the first displacement mechanism" procedure P2; a "wafer loading mechanism moves a wafer into the wafer ring" procedure P3; a "cover loading mechanism superimposes a cover on the wafer in the wafer ring to form an assembly" procedure P4; a "loading and unloading mechanism calibrates the loading and unloading operation surface" procedure P5; a "image capturing component inspects the image of the periphery of the assembly support portion to be assembled on the carrier and calibrates the imaging surface" procedure P6; and a "loading and unloading mechanism moves and locks the assembly onto the assembly support portion to be assembled" procedure P7; wherein:
[0104] The "Place the carrier, wafer ring, wafers, and cover in their respective positions" P1 procedure is to place an empty carrier 50 in a preset assembly position and place each wafer ring 2a, wafer 3a, and cover 4a in a preset feeding position; it sequentially includes the following steps: "The carrier is moved to the operating position on the second displacement mechanism" S11, "The wafer cassette containing the wafers is placed on the wafer loading mechanism; the wafer ring and cover are placed on the wafer ring loading mechanism and the cover loading mechanism respectively" S12, and "The wafer loading mechanism drives the wafer cassette to pivot so that its opening faces the first displacement mechanism" S13.
[0105] The "wafer ring loading mechanism moves a wafer ring into the first displacement mechanism" P2 program is driven by the control module to drive the wafer ring loading mechanism 2 to move a wafer ring 2a from the feed position and support it in the wafer pre-treatment portion 121 of the first base body 12; it has the "wafer ring loading mechanism moves a wafer ring and positions it in the first displacement mechanism" S21 step.
[0106] In the "wafer loading mechanism moves a wafer into the wafer ring" P3 program, the control module drives the wafer loading mechanism 3 to move a wafer 3a onto the first displacement mechanism 1 for alignment, and then places the wafer 3a into the wafer ring 2a. The program sequentially includes the following steps: "the wafer loading mechanism carries a wafer and levels the wafer during the movement process" S31; "the wafer loading mechanism moves the wafer onto the first displacement mechanism and aligns the wafer" S32; and "the first displacement mechanism moves the wafer into the wafer ring" S33.
[0107] The "cover loading mechanism places a cover on the wafer in the wafer ring to form an assembly" P4 program has the control module drive the cover loading mechanism 4 to move a cover 4a into the wafer ring 2a and overlay it on the wafer 3a, thereby overlaying the wafer ring 2a, wafer 3a, and cover 4a to form an assembly 20a. The peripheral side of the wafer 3a is firmly clamped between the peripheral edges of the wafer ring 2a and the cover 4a, so that the wafer 3a can maintain good flatness in the assembly 20a. It also has the "cover loading mechanism places a cover into the wafer ring and overlays it on the wafer to form an assembly" S41 step.
[0108] The "Loading and unloading mechanism correction loading and unloading working surface" P5 program is driven by the control module to adjust the position of the loading and unloading mechanism 62 on the robot arm 6 so that each distance measuring element 621 measures the same distance around the assembly support portion 501 to be assembled at a position to be assembled on the carrier 50, so that the loading and unloading mechanism 62 can be parallel (with the same tilt angle) and positively correspond to the assembly support portion 501 to be assembled, thereby correcting the tilt angle of the loading and unloading working surface of the loading and unloading mechanism 62, and the control module stores the information of the corrected loading and unloading working surface; it sequentially includes the following steps: "The robot arm drives the loading and unloading mechanism to approach the carrier with a preset loading and unloading reference value, and uses the distance measuring element to measure the distance to the edge of the assembly support portion to be assembled" S51, and "The control module adjusts the position of the loading and unloading mechanism so that the measured distances of each distance measuring element are of the same length, thereby correcting the tilt angle of its loading and unloading working surface" S52.
[0109] The "image capture component inspects the image of the periphery of the assembly carrier portion to be assembled on the carrier and corrects the imaging surface" P6 program, the control module drives the image capture component 61 on the robot arm 6 to inspect the image of the periphery of the assembly carrier portion 501 to be assembled and each clamp 502 according to the inclination angle and direction of the loading and unloading working surface after the correction, and adjusts the position of the image capture component 61 to correctly correspond to the assembly carrier portion 501 to be assembled and its clamp 502, so as to correct the position of the imaging surface of the image capture component 61, and the control module stores the information of the imaging surface after the correction, and the control module uses the information of the imaging surface after the correction to further correct the image capture. Correct the relative position of the loading and unloading operation surface so that the loading and unloading operation surface can accurately correspond to the position of the assembly carrier 501 to be assembled and its clamp 502; it has the following steps in sequence: "The robotic arm drives the image capture component to approach the carrier at the same inclination angle as the corrected loading and unloading operation surface, and obtains the position image of the assembly carrier and each clamp to be assembled" S61 step, "The control module adjusts the position of the image capture component so that it correctly corresponds to the assembly carrier to be assembled, thereby correcting the position of its imaging surface, and using the information of the corrected imaging surface to correct the loading and unloading operation surface so that it is positive and accurately corresponds to the assembly carrier to be assembled" S62 step.
[0110] The "loading and unloading mechanism moves and locks the assembly onto the assembly carrying portion to be assembled" P7 program is driven by the control module to drive the loading and unloading mechanism 62 on the robot arm 6 to move and lock the assembly 20a onto the assembly carrying portion 501 to be assembled; it sequentially includes: "The loading and unloading mechanism unlocks each clamp" S71 step, "The loading and unloading mechanism moves the assembly onto the assembly carrying portion to be assembled" S72 step, "The loading and unloading mechanism locks each clamp to fix the assembly" S73 step, and "The loading and unloading mechanism disengages from the assembly, and the carrier rotates" S74 step.
[0111] The following is combined Figures 5 to 33 , respectively describe the above steps and form a practical and feasible application embodiment:
[0112] First, in the step S11 of "moving the carrier to the working position on the second displacement mechanism", the control module first drives the second displacement mechanism 5 to move the second base 52 to the end of each second guide rail 51 away from the first displacement mechanism 1, so as to place an empty carrier 50 on the second base 52 (such as Figure 5 Then the second base 52 carries the carrier 50 along each second guide rail 51 to a preset operating position close to the first displacement mechanism 1 (such as Figure 6 shown).
[0113] The step S12 of "placing the wafer cassette for accommodating wafers on the wafer loading mechanism; placing the wafer ring and the cover on the wafer ring loading mechanism and the cover loading mechanism respectively" is to stack a plurality of wafer rings 2a on the wafer ring feeding seat 21 of the wafer ring loading mechanism 2 (i.e., the feeding position of the wafer ring 2a), and place a plurality of wafer cassettes 30a containing wafers 3a spaced apart therein on the wafer feeding seat 31 of the wafer loading mechanism 3 (i.e., the feeding position of the wafer 3a), and stack a plurality of covers 4a on the cover feeding seat 41 of the cover loading mechanism 4 (i.e., the feeding position of the cover 4a); then the first base 12 can be moved to a position close to the side of each first guide rail 11 of the wafer ring loading mechanism 2 as needed (e.g., Figure 5 shown).
[0114] The step S13 of "the wafer loading mechanism drives the wafer cassette to pivot so that its opening faces the first displacement mechanism" is to make the wafer feeder 31 rotate the opening of each wafer cassette 30a to the side facing the first displacement mechanism 1 (such as Figure 6 shown).
[0115] In the step S21 of "the wafer ring loading mechanism moves and positions a wafer ring in the first displacement mechanism", the control module drives the wafer ring loading mechanism 2, so that the clamping assembly 233 of the wafer ring displacement assembly 23 clamps a wafer ring 2a on the wafer ring feeding seat 21, and moves the wafer ring 2a into the wafer pre-treatment portion 121 of the first seat body 12 (such as Figure 7 、 Figure 8 、 Figure 9 Then, the clamping assembly 233 is separated from the wafer ring 2a, so that the wafer ring 2a can be used to rest on the edge of the wafer pre-treatment portion 121 using the outer ring flange 21a (as shown); Figure 10 As shown) to form positioning.
[0116] In actual application, the wafer ring lifting assembly 22 can cooperate to drive the wafer ring feeding base 21 to move up and down, so that the wafer ring displacement assembly 23 can more easily clamp the wafer ring 2a at an appropriate position.
[0117] In the step S31 of "the wafer loading mechanism carries a wafer and guides the wafer level during the transfer process", the control module drives the wafer loading mechanism 3 to move the wafer transfer slide 332 of the wafer transfer assembly 33, and the telescopic assembly 333 is extended to allow the wafer holder 34 to extend into a wafer cassette 30a to support a wafer 3a (such as Figure 11 As shown), the wafer 3a is then moved out of the wafer cassette 30a (as shown Figure 12 As shown) and approach the nozzle 35, the nozzle 351 of the nozzle 35 is used to spray air to blow on the wafer 3a (as shown Figure 13 、 Figure 14 As shown), the wafer 3a can be leveled, and then each exhaust hole 341 is exhausted, so that the wafer 3a can be stably positioned in the correct position on the wafer holder 34 and avoid warping.
[0118] In actual application, the wafer lifting assembly 32 can cooperate to drive the wafer feeder 31 to move up and down, so that the wafer holder 34 can more easily support the wafer 3 a in the wafer cassette 30 a at an appropriate position.
[0119] In the step S32 of "the wafer loading mechanism moves the wafer onto the first displacement mechanism and guides the wafer", the control module drives the wafer loading mechanism 3 so that the wafer displacement assembly 33 drives the wafer holder 34 to move the wafer 3a to the upper portion of the wafer pre-treatment portion 121 of the first base 12 (such as Figure 15 As shown), the image of the wafer 3a is obtained by the imaging unit 16 to check whether the position of the wafer 3a is correct. In addition, the two jacket slides 15 with backlight surfaces can be fitted together to combine the two concave arc portions 151 into a circular hole corresponding to the wafer pre-treatment portion 121 (as shown). Figure 16 As shown), the wafer shifting assembly 33 drives the wafer holder 34 to correct the position so that the wafer 3a is guided and located at a position corresponding to the center of the concave arc portion 151 of the second sleeve slide 15 (ie, the center of the wafer ring 2a).
[0120] In the step S33 of "the first displacement mechanism moves the wafer into the wafer ring", the two jacket slides 15 are separated, and the support base lifting assembly 133 drives the support base 13 to rise, and at the same time, the suction holes 132 are evacuated, so that the wafer 3a can be adsorbed on the support base 13. At this time, the suction holes 341 of the wafer holder 34 stop evacuating air, and the wafer holder 34 is separated from the bottom surface of the wafer 3a in the groove 131 (such as Figure 17 Then the telescopic component 333 is retracted, so that the wafer holder 34 is moved out of the first base 12 (as shown); Figure 18 and then the support base lifting assembly 133 drives the support base 13 down, so that the wafer 3a moves down on the inner ring flange 22a of the inner periphery of the wafer ring 2a (as Figure 19 As shown), the wafer 3a remains adsorbed by the support base 13.
[0121] In the step S41 of "the cover loading mechanism moves a cover into the wafer ring and stacks it on the wafer to form an assembly", the first base 12 can be moved along the first guide rail 11 to a position close to the side of the cover loading mechanism 4 (such as Figure 20 and then the control module drives the cover loading mechanism 4, so that the cover displacement assembly 43 of the clamping jaw group 433 clamps the cover feed seat 41 on a cover 4a of the annular convex portion 41a (such as Figure 21 、 Figure 22 As shown), and with the lifting and lowering of the cover displacement slide 432 and the horizontal sliding of the cover displacement guide rail 431, the cover 4a can be moved into the wafer pre-treatment portion 121 and superimposed on the wafer 3a (as shown Figure 23 、 Figure 24 Then, the jaw group 433 loosens the annular protrusion 41a (as shown); Figure 25 As shown), the stacked wafer ring 2a, wafer 3a, and cover 4a form an assembly 20a (as shown Figure 26 shown).
[0122] In actual application, the cover lifting assembly 42 can cooperate to drive the cover feeding seat 41 to rise and fall, so that the cover displacement assembly 43 can more easily clamp the cover 4a at an appropriate position.
[0123] In the step S51 of "the robot arm drives the loading and unloading mechanism to approach the carrier at a preset loading and unloading reference value, and uses the distance measuring element to measure the distance to the edge of the assembly support portion to be assembled" the control module drives the loading and unloading mechanism 62 on the robot arm 6 to move to a position to be assembled on the carrier 50 in the direction and angle of the preset loading and unloading reference value; and uses each distance measuring element 621 to detect the distance to the peripheral side of the assembly support portion 501 to be assembled at the position to be assembled (such as Figure 27 shown).
[0124] In a feasible embodiment, the distance measuring element 621 is a laser light source, which can project a laser beam 6211 onto the periphery of the assembly supporting portion 501 to be assembled, so as to detect the distance.
[0125] In step S52 of "the control module adjusts the position of the loading and unloading mechanism so that the measured distances of each distance measuring element are equal, thereby correcting the tilt angle of its loading and unloading working surface", the control module drives the loading and unloading mechanism 62 on the robot arm 6 to adjust its position according to the difference in the distance detected by each distance measuring element 621 (i.e., the projection length of the laser beam 6211), so that the distance (laser beam 6211) detected by each distance measuring element 621 (laser light source) on the circumference of the assembly support portion 501 to be assembled is equal, thereby correcting the tilt angle of the loading and unloading working surface of the loading and unloading mechanism 62 and ensuring that the surface on the bottom side of the loading and unloading mechanism 62 (i.e., the loading and unloading working surface) is parallel to the assembly support portion 501 to be assembled; and the control module can store information about the loading and unloading working surface after correction.
[0126] In the step S61 of "the robot arm drives the image capturing component to approach the carrier at the same inclination angle as the corrected loading and unloading operation surface, and obtains the position image of the assembly carrier portion to be assembled and each clamp", the control module drives the image capturing component 61 on the robot arm 6 to move to the top of the assembly carrier portion 501 to be assembled at the same inclination angle and direction as the corrected loading and unloading operation surface, and uses the imaging component 611 to obtain the image of the periphery of the assembly carrier portion 501 to be assembled (such as Figure 28 As shown), the positions of the assembly carrying portion 501 and each clamp 502 to be assembled are confirmed.
[0127] In the step S62 of "the control module adjusts the position of the image capturing component so that it correctly corresponds to the support portion of the assembly to be assembled, thereby correcting the position of its imaging surface, and using the information of the corrected imaging surface to correct the loading and unloading operation surface so that it is positive and accurately corresponding to the support portion of the assembly to be assembled", the control module drives the image capturing component 61 on the robot 6 to adjust its position according to the image position difference of the support portion 501 to be assembled, thereby correcting the imaging surface of the image capturing component 61 and ensuring that the image capturing component 61 correctly corresponds to the support portion 501 to be assembled and each clamp 502; and the control module can store the information of the corrected imaging surface (such as Figure 28 shown).
[0128] In a feasible embodiment, each fixture 502 is provided with a positioning mark (not shown, it can be a cross scale or other marking structure) at a preset position on the side surface, and a corresponding relative mark (not shown, it can be a cross scale or other marking structure) can be set on the lens of the imaging component 611 of the image capturing component 61; when the image capturing component 61 is adjusted to make the relative mark coincide with the positioning mark, the effect of correcting the position of the imaging surface of the image capturing component 61 can be achieved.
[0129] Since the image capture component 61 takes images at the same inclination angle and direction as the corrected loading and unloading operation surface, after correcting the position of the imaging surface, the control module can use the position of the corrected imaging surface to calculate and store the position information of the loading and unloading mechanism 62 that needs to be corrected again, so that the control module can directly and quickly drive the loading and unloading mechanism 62 to move to a position that is correctly corresponding to the assembly support part 501 to be assembled via the robotic arm 6 again.
[0130] In the step of "unlocking each clamp by the loading and unloading mechanism" S71, the control module first drives the loading and unloading mechanism 62 on the robot arm 6 to move above the assembly supporting portion 501 to be assembled, and then uses each clamp operating component 623 to release each clamp 502 (such as Figure 29 shown).
[0131] In the step S72 of "the loading and unloading mechanism moves the assembly to be assembled onto the assembly supporting portion", the control module drives the loading and unloading mechanism 62 on the robot arm 6 to move to the wafer pre-treatment portion 121 of the first base 12, and uses the clamping component 622 to clamp the assembly 20a (at this time, the suction holes 132 stop suctioning, and the support base 13 releases the adsorption state of the wafer 3a, as shown in FIG. Figure 30 As shown), the assembly 20a is then moved onto the assembly support portion 501 to be assembled (as shown Figure 31 、 Figure 32 shown).
[0132] In the step S73 of "the loading and unloading mechanism locks each clamp to fix the assembly", the control module drives each clamp operating assembly 623 to lock each clamp 502 so that the assembly 20a can be fixed on the assembly supporting portion 501 to be assembled (such as Figure 32 shown).
[0133] In the step S74 of "the loading and unloading mechanism is separated from the assembly, and the carrier plate is rotated", after each clamping assembly 622 releases the assembly 20a, the control module drives the pivot assembly 53 to drive the carrier plate 50 to pivot, so that the assembly supporting portion 501 that has fixed the assembly 20a is pivoted to a side position, and the other vacant assembly supporting portion 501 on the side is moved to the original assembly position to be assembled to form another assembly supporting portion 501 to be assembled (such as Figure 33 As shown), the above steps are repeated to fix each assembly 20a on each assembly supporting portion 501 to be assembled on the carrier 50.
[0134] In summary, the pre-treated wafer carrier loading device and method of the present invention can achieve the effect of using simple mechanism and operation to respectively combine the wafer ring, wafer, and cover, and accurately move and fix them to different positions on a carrier.
