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 requires good marking quality. High cleanliness levels will ensure traceability and reliability.

Features
A laser is used to print the lot number (such as ABC1234) directly above the wafer to ensure the entire process chain's traceability. This lot number is composed of many recessed holes. There may be some derivatives after marking, which will accumulate around the pits. Excessive or hard protrusions may scratch the wafer's surface in the later process and cause the wafer to be scrapped. Ultraviolet laser processing is a cold processing method that solves accumulation, making it an ideal wafer marking program.
