1. Working mode: The loading robot automatically loads wafers from the A-B (recyclable) wafer box to the pre positioning
workbench, and through the adjustment of the camera positioning wafer and automatic rotation system, the pre positioning of the wafer is achieved; The loading robot then loads the pre positioned wafers onto the alignment workbench. Through computer image recognition and automatic alignment system adjustment, the automatic alignment of the graphics on the mask and the wafers can be achieved. It is also possible to complete one exposure without aligning the graphics. After automatic exposure by the overexposure system, the unloading robot automatically places the wafers into the C-D (recyclable) wafer box.
