Benchwork Jobs » Jobs In Assembly And Repair Of Electrical Equipment » Jobs In Assembly And Repair Of Electronic Components And Accessories Nec » Wafer Substrate Tester

Wafer Substrate Tester – Tests semiconductor wafer substrate, using testing equipment, for example 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, for example resistivity, capacitance, and voltage. Starts equipment and observes equipment readout to determine wafer electrical measurements. Records measurements in production log. Compares measurements with specification sheets to determine if wafer substrate meets company standards. Sorts, boxes, and labels tested wafers. Delivers wafers and process sheets to production line workers. Maintains production records. May also inspect wafer substrate surfaces, using ultraviolet lamp, to detect scratches and contamination.
