Term (Index) Definition
SOI, Silicon-on-Insulator  Silicon-On-Insulator; silicon substrate of choice in future generation CMOS ICs; basically a silicon wafer with a thin layer of oxide (SiO2) buried in it; devices are built into a layer of silicon on top of the buried oxide; SOI substrates provide superior isolation between adjacent devices in an integrated circuit as compared to devices built into bulk wafers (elimination of "latch-up" in CMOS devices); also, improved performance of SOI devices due to reduced parasitic capacitances.
