Abstract:
1. A semiconductor device including an inverter circuit in which complementary switching elements are connected in series between a power supply potential and a ground potential, comprising: a semiconductor substrate having a main surface; a power supply interconnection formed on a surface of said semiconductor substrate and extending in parallel to a first direction, to which a power supply potential is applied; a ground interconnection formed on the surface of said semiconductor substrate and extending in parallel to said first direction at a distance from said power supply interconnection in a second direction orthogonal to said first direction, to which a ground potential is applied; and two element formation regions for said complementary switching elements, each defined by an element isolation insulating film in a region of said semiconductor substrate lying between said power supply interconnection and said ground interconnection, each said element formation region having formed said gate interconnection portion including said second gate interconnection portion being arranged such that a distance in parallel to said first direction between said butting diffusion and said second gate interconnection portion gradually increases as said second gate interconnection portion extends from said first gate interconnection portion.
