Abstract:
1. A semiconductor device, comprising: an upper substrate on which a plurality of through holes are formed; a lower substrate; and a plurality of semiconductor substrates provided between said upper substrate and said lower substrate, said plurality of semiconductor substrates forming a fixed electrode and a variable electrode, and each having a potential drawing portion, abutting on said through holes to draw potentials, wherein one of said plurality of semiconductor substrates is so formed as to surround a periphery of a region between said upper substrate and said lower substrate, to form an outer peripheral frame, the others of said plurality of semiconductor substrates are disposed, being surrounded by an inner periphery of said outer peripheral frame formed by said one semiconductor substrate, and said potential drawing portion of said one semiconductor substrate is formed at a corner portion thereof.
