Abstract

A method of manufacturing a semiconductor device includes removing a low-resistivity metal film, conductive layer, third insulating film and an upper part of the electrode layer in a gate electrode isolation region with a gate forming pattern serving as a mask, forming a protecting film so that the protecting film covers the low-resistivity metal film, conductive layer, third insulating film and upper surface of the electrode layer, removing the protecting film formed on the upper surface of the electrode layer located in the upper surface of the electrode layer in the gate electrode isolation region, removing the electrode layer in the gate electrode isolation region, and removing residue of the protecting film.
