Abstract
Description
Technical Field
[0001] This utility model relates to a calibration device, and more particularly to a calibration auxiliary device for adjusting the transmission position within a semiconductor cavity. Background Technology
[0002] In wafer manufacturing, the closer the wafer center aligns with the center of the electrostatic chuck (ESC), the better. Better adhesion leads to better heat dissipation on the back of the wafer, better meeting process requirements and resulting in higher product yield. During wafer transfer, a robotic arm needs to precisely deliver the wafer to its designated position. Therefore, the robotic arm's position needs to be calibrated beforehand. However, in actual operation, engineers find it difficult to achieve precise positioning with the naked eye, and calibration is time-consuming and inefficient. Therefore, developing a calibration auxiliary device for adjusting the transfer position within a semiconductor cavity has become a pressing problem for those skilled in the art.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.
[0016] like Figure 1 , Figure 2 and Figure 3 As shown, a calibration auxiliary device for adjusting the transfer position within a semiconductor cavity includes a stage 1, a central calibration module 2, and a movable elevation assembly 3. The bottom of the stage 1 has a notch 101 that precisely aligns with the positioning notch 401 on the electrostatic chuck 4. The central calibration module 2 is located at the center of the stage 1. The central calibration module 2 is used for positioning with a robotic finger 5, making the calibration position faster, more accurate, and more convenient, achieving rapid and accurate positioning. The central calibration module 2 has a calibration guide shape (such as...) that cooperates with the front end of the robotic finger 5. Figure 1 The cylindrical surface 201 of the side wall of the central calibration module 2 shown in the figure matches the arc-shaped groove 501 at the front end of the mechanical finger 5. The platform 1 and the central calibration module 2 are integrally formed and made of acrylic material.
[0017] The platform 1 has a guide slot 6 in the middle, the center calibration module 2 is located in the center of the guide slot 6, and the guide slots 6 on both sides of the center calibration module 2 are provided with positioning pins 7.
