Abstract
A semiconductor device includes a substrate having an active pattern, a cell region on the substrate and having a cell circuit, and a core region on the substrate having a peripheral circuit. In plan view, the active pattern on the core region includes a plurality of corners. Each of the corners has a rounding index that is equal to or less than about 15 nm. The rounding index is a distance between a respective tip of each of the corners and a right-angled corner.
