Filed: 1985-03-13
Abstract: PURPOSE:To increase gate withstanding voltage up to original oxide-film withstanding voltage by disposing a gate oxide film in a gate section for a MOS type transistor while being separated from a diffusive isolation edge. CONSTITUTION:Compensating gates 12, 12' are formed at positions where a gate 2 crosses with the edges of diffusive isolations 4, that is, in a shape that film-quality deteriorating sections 7' in a gate oxide film are coated. The gate oxide film 7 is not brought into contact with the edge sections of the diffusive isolation films 4 and a P<+> channel stopper section 6 by the compensating gates 12, 12', and has only a section excellent as the quality of a film. The film thickness of inter-layer insulating films 13 among the compensating gates 12, 12' and the gate 2 generally extends over approximately 100nm-200nm, and is made sufficiently thicker than the film thickness of 30nm-60nm of the gate oxide film 7, thus preventing a lowering due to the insertion of the compensating gates 12, 12' of the withstanding voltage of the gate 2.
