Semiconductor Wafer Inc ( SWI ) provides high quality SOI wafer ( Silicon-on-Insulator ) for a varity of application including MEMS , Power device , Pressure sensors and CMOS integrated circuit fabrication .
SOI wafer provide a potential solution for high speed and low power consumption device and has been widely acknowledged as a new solution for high voltage and RF components. SOI wafer is a sandwich structure including a device layer ( active layer ) on top , a buried oxide layer ( insulating SiO2 layer ) in the middle , and a handle wafer ( bulk silicon ) in the bottom . SOI wafers are produced by using SIMOX and wafer bonding technology to achieve thinner and precise device layer and ensure the requirement of thickness uniformity and low defect density .
SWI can provide SOI wafer in diameter 4" and 8 " with flexible thickness and wide resistivity range to meet your unique SOI requirements .
