Day-to-Day Responsibilities
Write and run test programs on automatic test equipment (ATE) that check each chip's electrical behaviour.
Probe wafers and test packaged chips, then log pass and fail results for every production lot.
Analyse test data to spot patterns, such as a fault that repeats in one part of a wafer.
Work with design and fabrication teams to find the root cause of failing chips and confirm fixes.
Set up, calibrate and maintain test boards, probe cards and test equipment in the lab.
Debug test programs for new chip samples before volume production begins.
Follow cleanroom, safety and quality procedures, and document every change to a test flow.
