Abstract
A semiconductor layout structure includes a substrate comprising a cell edge region and a dummy region abutting thereto, a plurality of dummy contact patterns disposed in the dummy region and arranged along a first direction, and a plurality of dummy gate patterns disposed in the dummy region and arranged along the first direction. The dummy contact patterns and the dummy gate patterns are alternately arranged. Each dummy contact pattern includes an inner dummy contact proximal to the cell edge region and an outer dummy contact distal to the cell edge region, and the inner dummy contact and the outer dummy contact are arranged along a second direction perpendicular to the first direction and spaced apart from each other by a first gap.
