Companies that manufacture electronic components commonly use laser engraving for
final product identification as well as identifying work-in-progress. In fact, the first widespread production use of laser engraving was to serialize silicon wafers on integrated circuit production lines.

Laser engraving is also used for metal etching and plastic packages that house
microelectronic circuits. Marking speed, permanency, legibility, and the
noncontaminating nature of laser engraving are all qualities that the electronics
industry demand. Laser Impressions, Inc. has equipment to automatically process
silicon wafers; JEDEC tray handlers for I.C. packages; and software for all SEMI
standard fonts, including 2D matrix codes.
