    摘要: A semiconductor device comprises a complementary MOS transistor integrated circuit formed in a semiconductor single crystal silicon disposed on an electrically insulating layer. A thickness of the single crystal silicon in a region in which an N-type MOS transistor is formed is made thicker than the thickness in a region in which a P-type MOS transistor is formed. By this structure, the bottoms of the source region and the drain region of the N-type transistor are separated from the electrically insulating layer by a predetermined distance. The separation of the source region and the drain region from the electrically insulating layer is effective to prevent a parasitic channel from forming, thereby reducing leakage current and making the semiconductor device more efficient.

    摘要: A semiconductor substrate is utilized to integrally form a drive circuit and a pixel array to produce a transparent semiconductor device for a light valve. The semiconductor device for a light valve is constructed by a semiconductor substrate composed of a bulk single crystal silicon having an opaque thick portion and a thin transparent portion. A pixel array is formed in the transparent portion. A drive circuit is formed in a top face of the opaque portion. A transparent support substrate is laminated to the top face of the semiconductor substrate for reinforcement. A bulk portion of the semiconductor substrate is removed from a back face thereof by selective etching to provide the transparent portion.

    摘要: A semiconductor substrate is utilized to integrally form a drive circuit and a pixel array to produce a transparent semiconductor device for a light valve comprising a pixel array region and a drive circuit region on a major face of the semiconductor substrate. A stopper film is formed on the major face of the semiconductor substrate at the pixel array region, and a pixel array is formed over the silicon oxide stopper film. A drive circuit is formed on the drive circuit region, and silicon oxide posts are embedded in the major face of the semiconductor substrate at the drive circuit region. A thickness of the semiconductor substrate is then selectively removed from a back face opposite to the major face thereof to reach the stopper film. After the selective removing step, the portion of the semiconductor substrate under the pixel region is completely removed while a portion of the semiconductor substrate under the drive circuit region remains.
