Abstract
A semiconductor device includes a first n-type source/drain regionand a second p-type source/drain regionformed on a semiconductor substrateaway from side surfaces of first and second gate electrodesat a first interval Wrespectively, a second n-type source/drain regionand a first p-type source/drain regionformed on the semiconductor substrateaway from side surfaces of third and fourth gate electrodesat a second interval W, which is wider than the first interval W, respectively, and third and fourth insulating sidewallsextended onto source/drain extensionson both sides of third and fourth gate electrodesfrom edges of upper surfaces of the third and fourth gate electrodesrespectively.
