Patent ID: 7719034

Claim:
A semiconductor device, comprising: a cell region and a peripheral region defined on a semiconductor substrate; first and second active regions formed facing each other on the peripheral region, the first and second active regions each comprising a recessed portion and a protruding portion, wherein the recessed portion of the first active region faces the protruding portion of the second active region, a width of each recessed portion being smaller than a width of each protruding portion; a first gate pattern longitudinally extending on the first active region, wherein the first gate pattern defines a first side of the first active region and an opposite second side of the first active region, the first side of the first active region including the protruding portion and the recessed portion of the first active region, the second side of the first active region comprising a linear edge; a second gate pattern longitudinally extending parallel to the first gate pattern on the second active region, wherein the second gate pattern defines a first side of the second active region and an opposite second side of the second active region, the first side of the second active region including the protruding portion and the recessed portion of the second active region, the second side of the second active region comprising a linear edge; at least one first contact hole formed in the protruding portion of the first side of each of the first and second active regions; and a plurality of second contact holes formed in the second side of each of the first and second active regions.
