A novel high-performance lateral bipolar on SOI

A novel lateral bipolar structure on SOI (silicon-on-insulator) is described. This device has a thin double-diffused base and a narrow emitter width, determined by the SOI thickness. It has minimal parasitic junction capacitance, as well as minimal emitter and collector resistances. Excellent device characteristics and an f/sub T/ of about 20 GHz were demonstrated.<
