Abstract
In a semiconductor integrated circuit device, a cell having no logical function placed in an end row of a plurality of cell rows includes: a third transistor opposed to a transistor of a cell adjacent in the Y direction; a third buried power line supplying VSS placed on the same side of the third transistor as the transistor of the adjacent cell; and a fourth buried power line supplying VDD placed on the opposite side of the third transistor from the transistor of the adjacent cell. The fourth buried power line is greater in size in the Y direction than the third buried power line.
