2'' To 12'' P Type N Type Silicon Wafer With High Resistivity for Semiconductor
BonTek produce silicon wafers (12 inches or less) for semiconductors in an integrated manner ranging from single crystal ingots to wafer processing. We have established the supply system mainly for the mass-produced wafers for bipolar integrated circuits, discrete circuits, and MEMS.
Silicon wafers are manufactured by cutting, polishing and cleaning single crystals of high-purity silicon under a strict production and quality control system. Diameter provided 4in, 5in, 6in, 8in, and 12inch.
