US Patent 7058922 Semiconductor integrated circuit and method of manufacturing the same

A multi-input logic circuit (e.g. a 2-input NAND circuit) mounted on a semiconductor integrated circuit comprises a plurality of voltage-activated transistors which have the same channel conduction type and are electrically connected in series between a power supply terminal and an output terminal. A source region and a body region of at least the voltage-activated transistor connected to the output terminal are electrically connected and have substantially the same potential. The semiconductor integrated circuit has either an SOI or SOS structure.
