Abstract

A semiconductor device has a FinFET with at least two independently controllable FETs on a single fin. The fin may have a body area with a width between two vertical sides, each side has a single FET. The fin also may have a top fin area that is wider than the body area and is electrically independent from the two FETs. The top fin area may be capable of receiving a body contact structure which may be connected to an electrical conductor as to regulate the voltage in the body area of the fin.
