Defect Inspection Engineer (f/m/d)

In this role you ensure defect-free wafer quality using AOI and unpatterned wafer inspection, working in a cleanroom and across process, equipment, and integration teams. You will set up and optimize inspection recipes, fine-tune parameters, and analyze defect data to drive process improvements. You’ll communicate findings with cross-functional teams and generate defect maps and reports. This position offers the chance to shape inspection for an integrated graphene photonics flow and contribute to a culture of continuous learning.
