AI Overview
Germanium (Ge) ingot slicing involves cutting highly purified, single-crystal cylinders into thin wafers using techniques like
Wire Electrical Discharge Machining (WEDM) or diamond saws. WEDM uses a thin molybdenum wire with electricity for high precision, lower material waste, and less cracking, while diamond saws are also commonly used. These techniques often follow Czochralski (CZ) crystal growth.
