ABSTRACT:
An integrated circuit has semiconductor devices on a substrate. The devices each have gates of polycrystalline silicon and the devices are insulated from each other by a stopper diffused into the substrate between said devices at least in the regions adjacent said gates. Reliability of the integrated circuit is improved by having each polycrystalline silicon gate formed with a region adjacent said stopper diffused with impurity of the same polarity as the impurity diffused in said stopper.
