Profile: SUMCO Phoenix Corp. is a manufacturer of electronic-grade silicon wafers for the semiconductor industry. We offer a full range of advanced silicon technologies, such as hydrogen-annealed, argon-annealed, bonded SOI (silicon-on-insulator), SIMOX (Separation by Implanted Oxygen), and heavily-doped, low-resistivity wafers. The iGEM™ is available in 150 mm diameter. It reduces junction leakage, resulting in increased device yields. We manufacture heavily-doped, Power IC and Power Discrete epi wafers in all thicknesses of epi up to 120 microns, and in diameters including 100, 125, 150 and 200 mm.
