- the control module 4 controls the motion module 3 to adjust the position of the rotary table 6 according to the positional offset information of the center of the silicon wafer 7 with respect to the center of the rotary table 6, and completes the pre-alignment work of the silicon wafer 7, specifically, including The following three steps:
- the control module 4 drives the lifting module 32 to drive the rotating table 6 and the silicon wafer 7 to move downward according to the positional deviation information of the center of the silicon wafer 7 with respect to the center of the rotating table 6, and reaches the intersection with the positioning table 8, that is, The upper surface of the positioning table 8 is used to transfer the silicon wafer 7 to the positioning table 8. At this time, the silicon wafer 7 is adsorbed on the positioning table 8, and then the lifting module 32 drives the rotating table 6 to continue downward movement to reach below the positioning table 8.
- the adjustment position is located between the positioning table 8 and the lifting module 32, and the specific position can be set as needed;
- the control module 4 controls the linear module 33 to drive the rotary table 6 to compensate in the X direction according to the offset, so that the center of the rotary table 6 coincides with the center of the silicon wafer 7; after the adjustment is completed, the control module 4 controls the lift mode.
- the group 32 drives the rotary table 6 to move up to the transfer position, so that the silicon wafer 7 is separated from the positioning table 8 and returned to the rotary table 6;
- the rotation module 31 drives the rotation table 6 to rotate to rotate the notch position of the silicon wafer 7 to the side of the pre-alignment lens 12, and collects the position information of the notch through the image sensor, and the data processing component is notched.
- the position information is processed to obtain the vertex position of the notch, and the control module 4 issues a command to the rotation module 31.
- the rotation module 31 rotates according to the command, so that the silicon chip notch is under the pre-alignment lens 12, and then the rotation module 31 is small.
- the angle is rotated back and forth 2 to 3 times, and the gap information is accurately collected.
- the data is fed back to the rotation module 31 to compensate the rotation angle until the precise orientation of the silicon wafer 7 is achieved.
- the motion module 3 drives the rotary table 6 to move to the edge exposure module 2 side by a corresponding distance; specifically, if the radius of the silicon wafer 7 is 12 inches, the linear module 33 does not need to move; The radius of the silicon wafer 7 is 8 inches, and the control module 4 drives the linear module 33 to move to the side of the edge exposure module 2 for a distance such that the edge of the 8-inch silicon wafer 7 is located at the edge exposure module 2.
- the control module 4 drives the linear module 33 to move to the side of the edge exposure module 2 for a distance such that the edge of the 6-inch silicon wafer 7 is located at the edge exposure module 2.
- the movement is 150 mm;
- the control module 4 controls the edge exposure module 2 to perform edge exposure processing on the silicon wafer 7. Specifically, the control module 4 turns on the exposure light source to emit ultraviolet band light, and controls the variable field of view diaphragm to adjust according to the width of the exposure required.
- the ultraviolet band fiber is exposed to the edge of the silicon wafer 7 through a variable field stop for exposure processing.
- the linear module 33 and the rotation module 31 can be adjusted by the control module 4.
- the silicon wafer processing apparatus and method provided by the present invention simultaneously achieve pre-alignment and edge exposure processing of the silicon wafer 7 by providing the pre-alignment module 1 and the edge exposure module 2, thereby reducing the occupied space of the system;
- the linear module 33 drives the lifting module 32 and the rotating module 31 to move in the horizontal direction, thereby realizing the pre-alignment and edge exposure functions of the silicon wafers 7 of different sizes, and the switching axis is realized by using a linear module 33.
- the common function of the centering shaft reduces the control object, simplifies the control difficulty and the complexity of the system structure design, and only needs to compensate the position deviation of the silicon wafer 7 from the X direction in the pre-alignment centering process. Reduced operational complexity of pre-alignment, greatly reducing energy consumption and cost.
