Semiconductor device for a light wave |
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.
