Patent ID: 8183114

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) preparing a substrate; (b) forming a first active region in the substrate and forming a second active region, which is separated from the first active region, in the substrate; (c) forming a first gate electrode region which is crossed by the first active region, and separated from the second active region, and forming a second gate electrode region which is crossed by the first active region and the second active region, and separated from the first gate electrode region, and forming a third gate electrode region which is separated from the first active region, the first gate electrode region and the second gate electrode region; (d) after step (a) to (c), forming an insulating film, which is separated from a top of the first gate electrode region, a top of the second gate electrode region and a top of the third gate electrode region, over the substrate; (e) after step (d), etching the insulating film and the third gate electrode region so as to form a groove on the third gate electrode region, on the first active region, on the second active region and over a region between the first active region and the second active region; (f) after step (a) to (e), forming a conductive film over the substrate; and (g) after step (f), removing the conductive film out of the groove, reaching the top of the first gate electrode region, the top of the second gate electrode region and the top of the third gate electrode region and forming a wiring which connects the first active region, the second active region and the third gate electrode region.
