Patent ID: 7547602

Claim:
A method of manufacturing a semiconductor integrated circuit device, comprising steps of: providing a substrate with projecting island regions formed in stripes, with first regions of a main surface of the substrate adjacent to the projecting island regions and with a conductive film covering at least a portion of the projecting island regions and the first regions, wherein an insulating film is formed between the projecting island regions and the conductive film, wherein the projecting island regions extend in a first direction in stripes; and performing anisotropic etching to the conductive film by using a mask covering contact regions so as to form conductive lines on side surfaces of the projecting island regions and the contact regions integrated with the conductive lines such that the contact regions are formed on the first regions and extend in a second direction crossing to the first direction, wherein the conductive lines serves as common gate electrodes for MISFETs arranged, in the first direction, adjacent to each other.
