Lithography Wafer Test System

0.5 mm probe, 4-axis robot

A custom-configured process analysis system for lithography wafers, from development through small-volume production. It handles blank wafers before etching, etched and coated wafers, singulated dies and loose MESA. Image processing locates each sub-die; a high-precision 4-axis robot holds repeatable positioning.
