TFSOI BiCMOS technology for low power applications

Abstract
A thin film silicon on insulator BiCMOS technology has been developed for low power applications. The technology is based on a manufacturable, near-fully-depleted 0.5 /spl mu/m CMOS process with the lateral bipolar device integrated as a drop-in module for BiCMOS circuits. The bipolar device structure emphasizes use of a silicided polysilicon base contact to reduce base resistance and minimize current crowding effects. A split-oxide spacer integration is used to define the bipolar base and emitter widths independently. Low current ECL gate speeds up to 2/spl times/ faster than bulk double-polysilicon self-aligned bipolar circuits have been demonstrated.<>
