ABSTRACT:
A semiconductor device having the grounds of element regions are provided in a semiconductor substrate. The device comprises a semiconductor substrate of a first conductivity type, at least two element regions of a second conductivity type, provided in a semiconductor substrate and having grounds connected to said semiconductor substrate when said semiconductor substrate is set at a fixed potential and at least one ground-isolating well region of the second conductivity type, provided between said at least two element regions to electrically isolate said at least two element regions by forming a depletion layer between said at least two element regions when applied with a reverse bias voltage.
