Features
A laser is used to print the lot number (such as ABC1234) of the wafer directly above the wafer to ensure the traceability of the entire process chain. This lot number is arranged by many recessed holes, a byproduct of marking It will accumulate around the pits. Excessive or hard protrusions may scratch the surface of the wafer in the later process and cause the wafer to be scrapped. Ultraviolet laser processing is a cold processing method that can better solve the problem of accumulation. It is an ideal wafer marking program.
