Abstract
A semiconductor-on-insulator transistor device includes a source region, a drain region, a body region, and a source-side lateral bipolar transistor. The source region has a first conductivity type. The body region has a second conductivity type and is positioned between the source region and the drain region. The source-side lateral bipolar transistor includes a base, a collector, and an emitter. A silicide region connects the base to the collector. The emitter is the body region. The collector has the second conductivity type, and the base is the source region and is positioned between the emitter and the collector.
