01/01/2001· Typical commercial wafers in 1997 possess mieropipe defects densities ranging Processing of Silicon Carbide for Devices and Circuits 191 from 50-200/cm2. One fact often overlooked by device engineers is that the mieropipe defect density is non-uniform and often locally clustered on the wafer.
A SiC epitaxial wafer manufacturing method of the present invention includes: manufacturing a SiC epitaxial wafer including a SiC epitaxial layer on a surface of a SiC single crystal wafer while supplying a raw material gas into a chaer using a SiC epitaxial wafer manufacturing apparatus; and manufacturing a subsequent SiC epitaxial wafer after measuring a surface density of triangular

At present, wafer diameters are 50.8 mm or 76.2 mm; doping (usually with N for n-type and Al for p-type) at high levels produces resistivities in the 0.0x mWcm region. Or there is no doping for semi-insulating sf. 4H- and 6H-SiC polytypes are sold; for a more detailed look of some of the products that are available use the link.
An HPLC column (Supelco, 250-mm long, 8.5-mm i.d. X 12.5-mm 0.d.) was used for supercritical extraction of coal because it could withstand the high pressure and temperature (up to 2500 psi and 350"C, respectively).
