Abstract
A hybrid transistor is produced to have a substrate with a first (e.g., P type) well region and a second (e.g., N type) well region with an NP or PN junction therebetween. A MOS portion of the hybrid transistor has an (e.g., N type) source region in the first well region and a gate conductor overlying and insulated from the well regions. A drain or anode (D/A) portion in the second well region collects current from the source region, and includes a bipolar transistor having an (e.g., N+) emitter region, a (e.g., P type) base region and a (e.g., N type) collector region laterally separated from the junction. Different LDMOS-like or IGBT-like properties are obtained depending on whether the current is extracted from the hybrid transistor via the bipolar transistor base or emitter or both. The bipolar transistor is desirably a vertical hetero-junction transistor.
