Abstract

A dummy pattern that is inserted to stabilize the form of a transistor active region is implanted with an impurity of the same conductivity type as a well, and the impurity-doped region of the dummy pattern is supplied with a potential through a metal interconnection. Hence, fluctuation of a well potential due to noise hardly occurs, and a semiconductor device enduring latch up, for example, to a greater extent can be provided.
