Abstract
A first wiring to be connected as needed and second wirings to be disconnected as needed are formed three-dimensionally with an insulation film interposed therebetween. The first wiring comprises at least three first semiconductor regions of a second conductivity type formed at predetermined intervals in the surface of a semiconductor substrate of a first conductivity type, and second semiconductor regions of the first conductivity type formed between each pair of adjacent first semiconductor regions. The second wirings are formed on the first wiring through the insulation film and in a number equal to that of the second semiconductor regions. Each second wiring and the corresponding second semiconductor region are located within a spot of a radiating means radiated vertically onto the semiconductor substrate for switching the wirings.
