Integrated Circuit with a Power Transistor and a Driver Circuit Integrated in a Common Semiconductor Body

Abstract

An integrated circuit includes a power transistor and a drive circuit. The drive circuit includes at least one drive transistor. The power transistor and the at least one drive transistor are integrated in a common semiconductor body. The power transistor includes at least one transistor cell with a source region, a body region, a drift region, a drain region, and a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric. The at least one drive transistor includes active device regions integrated in a well-like structure comprising dielectric sidewall layers.
