Latest Patents

Koehler holds a patent for "Methods for making wafers with low-defect surfaces, wafers obtained thereby and electronic components made from the wafers." This innovative patent describes an electronic semiconductor component that features a crystalline wafer substrate with an active surface and a semiconductor layer coating the active surface. The semiconductor layer is designed to minimize surface defects, utilizing a crystalline wafer substrate made from sapphire or silicon carbide single crystals. The active surface is engineered to have a pit density of less than 500 pit/cm, preferably less than 100 pit/cm. The polishing method employed to achieve these specifications involves using a silicon suspension as a polishing agent and a polishing tool that is pressed onto the active surface with a pressure ranging from 0.05 to 0.2 kg/cm. The polishing motions are distributed statistically and uniformly over a 360° angle during the process.
