Wafer Laser Marking System
Wafer laser marking machine.
Laser marking is widely used in the semiconductor industry due to its apparent advantages such as high marking accuracy, fast speed, and permanent marking.
Wafer marking on the die with good marking quality, high cleanliness levels, ensure the traceability and reliability.

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.
