Abstract
A semiconductor device includes a semiconductor layer provided on a semiconductor substrate with an insulating film interposed therebetween. A gate electrode is provided on the semiconductor layer with a gate insulating film interposed therebetween, and a pair of source/drain regions are formed in the semiconductor layer so as to hold a body region under the gate electrode therebetween. A control section supplies voltages to the source/drain regions. The control section supplies the body region in an OFF state and ON state with a first voltage and a second voltage different from the first voltage, respectively. The second voltage is set such that a potential of the body region in the OFF state is substantially the same as a potential of the body region in the ON state.
