The silicon carbide crystal most commonly used as a semiconductor material is 4H-SiC wafer. However, silicon carbide crystals have multiple types. Once the conditions are not well controlled in the process of the silicon carbide crystal growth, the resulting silicon carbide crystal structure may be 3C, 6H, 15R, etc., [...]

Development of a gate metal etch process for gallium arsenide wafers
The reactive ion etching of TiWN, which is used as a gate metal on gallium-arsenide device wafers, was studied in a parallel-plate, single-wafer plasma reactor operating at a frequency of 13.56 MHz. We discuss [...]
Due to the wide band gap of SiC wafer, SiC does not absorb part or almost all of the visible light. The wavelength of the absorbed light depends on the band gap, the energy levels of the main impurities and the excited energy levels [...]
