Job Description:

• 1) Tests semiconductor wafer substrate, using testing equipment, such as probe tester, spectophotometer, and curve tracer, to evaluate electrical characteristics of wafer substrate: Places wafer, using tweezers, on test equipment that measures electrical characteristics of wafer substrate, such as resistivity, capacitance, and voltage.

• 2) Starts equipment and observes equipment readout to determine wafer electrical measurements.

• 3) Records measurements in production log.

• 4) Compares measurements with specification sheets to determine if wafer substrate meets company standards.

• 5) Sorts, boxes, and labels tested wafers.

• 6) Delivers wafers and process sheets to production line workers.

• 7) Maintains production records.

• 8) May inspect wafer substrate surfaces, using ultraviolet lamp, to detect scratches and contamination.
