What does a wafer probe process engineer do?

A Wafer Probe Process Engineer is responsible for developing, optimizing, and maintaining the processes used to electrically test semiconductor wafers before they are cut into individual chips. This role involves working with probe stations, designing test programs, analyzing test data, and troubleshooting issues to ensure product quality and yield. Wafer Probe Process Engineers collaborate closely with manufacturing, test, and design teams to improve testing methodologies and reduce defects. Their work is critical in identifying early defects in integrated circuits, thereby saving costs and improving overall production efficiency.
