Dummy & Test Silicon Wafers
Dummy & Test Silicon Wafers: Dummy and test wafers are used for tool setup, process qualification and handling exercises. Clarify whether prime-grade surface/particle performance is required or can be relaxed. For procurement, describe Material and orientation, diameter, base wafer, doping/resistivity, film type and thickness, polished faces, flat/notch and inspection level. We discuss product options and inspection requirements case by case, rather than publishing unsupported stock or tolerance guarantees.
