ABSTRACT:
A semiconductor device may comprise a partially-depleted SOI MOSFET having a floating body region disposed between a source and drain. The floating body region may be driven to receive injected carriers for adjusting its potential during operation of the MOSFET. In a particular case, the MOSFET may comprise another region of semiconductor material in contiguous relationship with a drain/source region of the MOSFET and on a side thereof opposite to the body region. This additional region may be formed with a conductivity of type opposite the drain/source, and may establish an effective bipolar device per the body, the drain/source and the additional region. The geometries and doping thereof may be designed to establish a transport gain of magnitude sufficient to assist the injection of carriers into the floating body region, yet small enough to guard against inter-latching with the MOSFET.
