The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
An embodiment of the present application provides a calibration apparatus for a wafer-cut workpiece, wherein a wafer is fixed on a side surface of the wafer-cut workpiece, and a schematic structural diagram of the calibration apparatus is shown in fig. 1, fig. 2, fig. 7A, and fig. 7B, and the calibration apparatus includes: the device comprises an installation platform 1, a driving mechanism 2 and a calibration mechanism 3; the mounting platform 1 is used for mounting the driving mechanism 2 and the calibration mechanism 3; the driving mechanism 2 comprises a cam 21 and a driver 22, the cam 21 is positioned at the top of the mounting platform 1, and the cam 21 is provided with a plurality of convex parts 211 and concave parts 212 which are alternately arranged; the driver 22 is used for driving the cam 21 to rotate; the calibration mechanism 3 comprises a plurality of movable bearing components 31, wherein the plurality of movable bearing components 31 are distributed radially along the radial direction of the cam 21 and are used for bearing the wafer cutting workpiece together, and the plurality of movable bearing components 31 are matched with the cam 21 and are used for being selectively and synchronously far away from or close to the cam 21 when the cam 21 rotates so as to calibrate the position of the wafer cutting workpiece.
As shown in fig. 1, fig. 2, fig. 7A and fig. 7B, the semiconductor processing equipment is used for performing a plasma dicing process, for example, but the embodiment of the present application is not limited to a specific type thereof, and a person skilled in the art can adjust the setting according to actual situations. The mounting platform 1 may be a rectangular plate-shaped structure, which is specifically disposed in a transfer chamber of a semiconductor processing apparatus, for mounting the driving mechanism 2 and the alignment mechanism 3, but the embodiment of the present application does not limit the specific shape of the mounting platform 1. The driving mechanism 2 is integrally arranged at the central position of the mounting platform 1 in a penetrating way, the driver 22 is positioned at the bottom of the mounting platform 1, and the cam 21 is positioned at the top of the mounting platform 1. The driver 22 may employ a servo motor or a stepping motor for driving the cam 21 to rotate precisely.

The calibration mechanism 3 is arranged at the top of the mounting platform 1, and the calibration mechanism 3 comprises four movable bearing components 31, wherein the four movable bearing components 31 are radially and uniformly distributed along the radial direction of the cam 21.

According to the embodiment of the application, the plurality of movable bearing assemblies are arranged on the periphery of the cam and radially distributed along the radial direction of the cam, and the convex part of the cam abuts against the movable bearing assemblies through rotation of the cam by a first preset angle, so that the plurality of movable bearing assemblies are synchronously far away from the cam, and at the moment, the plurality of movable bearing assemblies can jointly bear the wafer cutting workpiece; through the continuous rotation of the cam, the plurality of movable bearing assemblies can be close to the cam synchronously due to the fact that the plurality of movable bearing assemblies lose the abutting of the convex parts, the wafer cutting workpiece is driven to move to a concentric state towards the center of the cam, the position of the wafer cutting workpiece is calibrated, and therefore when the mechanical arm transmits the wafer cutting workpiece to the process chamber, the position of the wafer cutting workpiece and the position of the electrostatic chuck cannot deviate, and the yield of the wafer cutting workpiece is improved.

By adopting the design, the wafer cutting device is simple in structure, and can be arranged according to different wafer cutting workpieces 100, so that the applicability and the application range of the wafer cutting device are greatly improved.
It should be noted that the embodiments of the present application do not limit the specific shapes of the supporting portion 3151 and the engaging portion 3152, for example, the shapes of the supporting portion 3151 and the engaging portion 3152 may adopt an arc structure, so as to be suitable for the circular wafer cutting workpiece 100. Therefore, the embodiments of the present application are not limited thereto, and those skilled in the art can adjust the settings according to actual situations.

When the four movable carrier assemblies 31 synchronously approach the cam 21, the four engaging portions 3152 can push the four straight edges of the wafer cut workpiece 100 to move toward the center of the cam 21, so as to calibrate the wafer cut workpiece 100. However, the number of the movable carrier assemblies 31 is not limited to a specific number in the embodiment of the present application, as long as the number of the movable carrier assemblies 31 corresponds to the number of straight edges of the outer periphery of the wafer cut workpiece 100. Therefore, the embodiments of the present application are not limited thereto, and those skilled in the art can adjust the settings according to actual situations.
In an embodiment of the present application, as shown in fig. 1 to 4D, the calibration device further includes a plurality of ejector pin assemblies 4, the ejector pin assemblies 4 are disposed on the mounting platform 1 in a penetrating manner and are uniformly distributed along the circumferential direction of the cam 21; the plurality of ejector pin assemblies 4 are configured to be lifted when the cam 21 is placed at a first predetermined angle to support the wafer-cutting workpiece 100, and to drive the wafer-cutting workpiece 100 to be lowered and simultaneously placed on the bearing member 315, wherein when the cam 21 rotates at the first predetermined angle, the roller member 314 abuts against and contacts the convex portion 211 of the cam 21, so that the plurality of pull rod structures 312 are synchronously away from the cam 21; the plurality of pin assemblies 4 are further configured to lift the calibrated wafer-cutting workpiece 100 when the cam 21 rotates by a second predetermined angle, so that the wafer-cutting workpiece 100 can be transferred by the robot, wherein the bearing member 315 is away from the cam 21 by a predetermined distance L when the cam 21 rotates by the second predetermined angle.
As shown in fig. 1 to 4D, three ejector pin assemblies 4 are disposed on the mounting platform 1, and are uniformly and alternately distributed along the circumference of the cam 21, for supporting the wafer cutting workpiece 100 in cooperation with each other. A portion of the ejector pin assembly 4 is located at the bottom of the mounting platform 1, and the ejector pin 43 of the ejector pin assembly 4 may be located above the mounting platform 1, and the ejector pin 43 may be lifted and lowered with respect to the mounting platform 1 for contacting the bottom surface of the wafer cut workpiece 100. When the cam 21 rotates by a first predetermined angle, the roller 314 abuts against the convex portion 211 of the cam 21 to make the plurality of pull rod structures 312 away from the cam 21, that is, the alignment mechanism 3 is in an idle state, the robot can transfer the wafer cut workpiece 100 onto the alignment mechanism 3, at this time, the thimble 43 of the thimble assembly 4 is lifted so that a second distance L2 is provided between the top end of the thimble 43 and the supporting surface of the supporting portion 3151, and the second distance L2 may be set to be greater than 0 mm and less than 3 mm for supporting the wafer cut workpiece 100 in mutual cooperation, as shown in fig. 3C. Further, the three ejector pin assemblies 4 can drive the wafer-cutting workpiece 100 to descend, so as to drive the wafer-cutting workpiece 100 to descend onto the alignment mechanism 3, so that the wafer-cutting workpiece 100 is simultaneously placed on the plurality of bearing members 315, and a third distance L3 is provided between the ejector pin 43 of the ejector pin assembly 4 and the supporting surface of the supporting portion 3151, where the third distance L3 may be set to be greater than 0 mm and less than 3 mm, and the specific process may refer to fig. 4A to 4D. It should be noted that, in the embodiment of the present application, specific values of the third distance L3 are not limited, as long as the thimble 43 of the thimble assembly 4 is lower than the supporting surface of the supporting portion 3151, and therefore, the embodiment of the present application is not limited thereto.
Referring to fig. 5 to 6C, when the cam 21 rotates for the first predetermined angle and then continues to rotate, since the roller component 314 gradually loses the abutting of the convex portion 211, the roller component 314 can approach the cam 21 and is finally accommodated in the concave portion 212, that is, the plurality of bearing components 315 synchronously approach the cam 21, at this time, the calibration mechanism 3 is in the calibration state, and under the action of the plurality of bearing components 315, the wafer cutting workpiece 100 and the cam 21 are finally in the concentric state, as shown in fig. 5. When the cam 21 rotates by a second predetermined angle, the convex portion 211 of the cam 21 can push against the roller portion 314 again, the bearing portion 315 can be away from the cam 21 by a predetermined distance L, and at this time, the engaging portion 3152 of the bearing portion 315 is separated from the straight edge of the wafer-cut workpiece 100, so that the calibration mechanism 3 is in a transmission state, and the ejector pins 43 of the three ejector pin assemblies 4 are lifted simultaneously to drive the calibrated wafer-cut workpiece 100 to lift and separate from the supporting portion 3151, thereby facilitating the robot to take away the calibrated wafer-cut workpiece 100, as shown in fig. 6A to 6C. By adopting the design, the wafer cutting workpiece 100 can be transmitted by matching with the mechanical arm, so that the wafer cutting workpiece 100 is calibrated, the calibrated wafer cutting workpiece 100 is transmitted, mechanical interference with the mechanical arm is avoided, and the usability and the failure rate of the embodiment are improved.

Specifically, the bearing members 315 are made of resin, so that the supporting surfaces of the supporting portions 3151 have self-lubrication, and when the bearing members 315 are away from the cam 21 by a predetermined distance L, and the four bearing members 315 are simultaneously away from the cam 21, the position of the wafer cut workpiece 100 does not shift due to the self-weight of the wafer cut workpiece 100 and the self-lubrication of the bearing members 315, that is, the center of the wafer cut workpiece 100 is still overlapped with the center of the cam 21. Further, since the bearing component 315 is away from the cam 21 by a predetermined distance L, the engaging portion 3152 and the straight edge of the diced wafer 100 also have the predetermined distance L, so as to avoid the movement distance from being too large to drive the diced wafer 100 to shift, the predetermined distance L may be set to be greater than 0 mm and less than or equal to 0.5 mm. By adopting the design, the embodiment of the invention still keeps the concentric arrangement with the cam 21 in the process of conveying the calibrated wafer cutting workpiece 100, thereby further improving the calibration accuracy of the wafer cutting workpiece 100. It should be noted that the embodiment of the present application does not limit the specific material of the bearing component 315, as long as it has a self-lubricating characteristic with respect to the wafer-cutting workpiece 100.

Particularly, three mounting holes are formed in the mounting platform 1, and the three ejector pin assemblies 4 are respectively arranged in the three mounting holes in a penetrating mode. The telescopic cylinder 41 is located at the bottom of the mounting platform 1 and is aligned with the mounting hole. The bottom end of the bellows 42 is connected with the top of the telescopic cylinder 41, the bellows 42 is inserted into the mounting hole, and the top end of the bellows is used for mounting the thimble 43, and the top end of the thimble 43 can be used for contacting and abutting against the bottom surface of the wafer cutting workpiece 100. The telescopic cylinder 41 is used for driving the thimble 43 to extend and retract relative to the mounting platform 1 so as to drive the wafer cutting workpiece 100 to lift and descend. By adopting the design, the structure of the embodiment of the application is simple and easy to realize, and the application and maintenance cost of the embodiment of the application is greatly reduced.
In an embodiment of the present application, as shown in fig. 1, fig. 7A and fig. 7B, the driving mechanism 2 further includes a mounting frame 23, a coupler 24 and a transmission shaft 25, the mounting frame 23 is disposed at a bottom center position of the mounting platform 1, and the driver 22 is disposed at a bottom of the mounting frame 23; a coupling 24 is provided in the mounting frame 23 and is connected to an output shaft of the driver 22; the bottom end of the transmission shaft 25 is connected with the coupler 24, and the top end of the transmission shaft passes through the mounting platform 1 to be connected with the cam 21. Specifically, the mounting frame 23 may have a hollow cubic structure, and the mounting frame 23 is disposed at a central position of the bottom of the mounting platform 1 and fixedly connected to the mounting platform by welding or fastening members. The driver 22 can be a servo motor or a stepping motor, the driver 22 is disposed at the bottom of the mounting frame 23, an output shaft of the driver 22 can extend into the mounting frame 23, the coupler 24 is disposed in the mounting frame 23, two ends of the coupler are respectively connected to the output shaft and the transmission shaft 25, and the transmission shaft 25 penetrates through the mounting platform 1 and is connected to the cam 21. With the above design, the coupling 24 can absorb the vibration of the driver 22 greatly, so as to improve the accuracy of transmission and further improve the accuracy of calibration.
To further illustrate the implementation and advantages of the embodiments of the present application, a specific implementation of the present application is described below with reference to fig. 1 to 7B.
When the calibration mechanism 3 is in the idle state, the cam 21 rotates by a first predetermined angle, specifically referring to the position shown in fig. 3A, the convex portion 211 of the cam 21 abuts against the roller 314, and the elastic member 313 is in the stretching state, the stretching amount may be determined according to the elastic force of the elastic member 3132, and the elastic force of the elastic member 3132 may be set to be not less than 5N. The robot may transfer the wafer cut workpiece 100 onto the alignment mechanism 3, and the wafer cut workpiece 100 is placed on the plurality of ejector pin assemblies 4 in advance, as shown in fig. 4A and 4B. The thimble 43 of the thimble assembly 4 descends to drive the wafer-cutting workpiece 100 to fall on the plurality of bearing members 315 at the same time, and at this time, a third distance L3 is formed between the top end of the thimble 43 and the supporting surface of the supporting portion 3151 to prevent the thimble 43 and the wafer-cutting workpiece 100 from colliding and rubbing, and the third distance L3 may be set to 3 mm, as shown in fig. 4C and 4D.
Further, after the driver 22 drives the cam 21 to rotate by a first preset angle, the cam 21 is continuously driven to rotate counterclockwise, the elastic force of the elastic element 3132 can make the bearing component 315 move toward the center of the cam 21, because the moving distances of the four bearing components 315 are the same, the center of the wafer cutting workpiece 100 gradually approaches toward the center of the cam 21, and the roller component 314 is always attached to the outer peripheral surface of the cam 21, so that the movement of the wafer cutting workpiece 100 is relatively stable, as shown in fig. 5. After the cam 21 rotates to an angle (less than 45 °), the elastic force of the elastic member 3132 is gradually reduced due to the gradual reduction of the stretching amount of the elastic member 3132, until all four bearing members 315 clamp the wafer-cut workpiece 100 and the center of the wafer-cut workpiece 100 coincides with the center of the cam 21, at which time the elastic force of the elastic member 3132 is minimized, but the elastic member 3132 should still be in a stretched state, and the elastic force is not less than 3N, so as to ensure that the wafer-cut workpiece 100 is concentric with the cam 21. Further, when the driver 22 continuously drives the cam 21 to rotate to 45 °, the roller component 314 is completely separated from the convex portion 211 of the cam 21 and is located in the concave portion 212 of the cam 21, and since the elastic component 3132 is still in a stretched state, each of the bearing components 315 has an elastic force with the same magnitude and the same direction pointing to the center of the cam 21 for the wafer-cutting workpiece 100, so as to ensure that the center of the wafer-cutting workpiece 100 completely coincides with the center of the cam 21, thereby completing the station calibration of the wafer-cutting workpiece 100.
Finally, the driver 22 drives the cam 21 to rotate by a second predetermined angle, and the four bearing members 315 move away from the cam 21 at the same time, so that a predetermined distance L is formed between the engaging portion 3152 of the bearing member 315 and the straight edge of the wafer cut workpiece 100, where the predetermined distance L may be greater than or equal to 0 and less than or equal to 0.5 mm, as shown in fig. 6B and 6C. At this time, the three ejector pin assemblies 4 simultaneously drive the wafer-cutting workpiece 100 to ascend, so that the robot transfers the calibrated wafer-cutting workpiece 100 to the electrostatic chuck of the process chamber. Therefore, the embodiment of the application realizes the calibration and transmission of the wafer cutting workpiece 100 through a simpler structure, thereby avoiding the deviation of the positions of the wafer cutting workpiece 100 and the electrostatic chuck, and further improving the yield of products.
Based on the same inventive concept, the embodiment of the application provides semiconductor process equipment, which comprises: the robot arm is used for transmitting the wafer cutting workpiece before calibration to the calibration device and transmitting the wafer cutting workpiece after calibration to the process chamber.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
according to the embodiment of the application, the plurality of movable bearing assemblies are arranged on the periphery of the cam and radially distributed along the radial direction of the cam, and the convex part of the cam abuts against the movable bearing assemblies through rotation of the cam by a first preset angle, so that the plurality of movable bearing assemblies are synchronously far away from the cam, and at the moment, the plurality of movable bearing assemblies can jointly bear the wafer cutting workpiece; through the continuous rotation of the cam, the movable bearing assemblies can synchronously approach the cam and drive the wafer cutting workpiece to move to a concentric state towards the center of the cam due to the fact that the movable bearing assemblies lose the propping of the convex parts, and the position of the wafer cutting workpiece is calibrated, so that when the manipulator transmits the wafer cutting workpiece into the process chamber, the position of the wafer cutting workpiece and the position of the electrostatic chuck cannot deviate, and the yield of the wafer cutting workpiece is improved.
