Metal oxide semiconductor (MOS) device, metal oxide semiconductor (MOS) memory device, and method of manufacturing the same

摘要

A semiconductor device includes a first semiconductor layer that is formed on a first insulating layer; a second insulating layer that is formed on the first semiconductor layer; a second semiconductor layer that is formed on the second insulating layer; a first gate electrode that is formed on the second semiconductor layer; first conductive-source and drain layers that are formed in the second semiconductor layer and are arranged at sides of the gate electrode; and a first wiring layer that connects the first gate electrode to the first semiconductor layer.
