Abstract:
A method of manufacturing a semiconductor device may include forming first trenches that define active patterns extending in a first direction on a substrate, forming first insulating layers filling the first trenches, forming first mask patterns extending in the first direction while having a first width along a second direction perpendicular to the first direction, forming a second mask pattern extending in the first direction while having a second width along the second direction, and forming a second trench that partly defines an active region by executing a first etching process that etches the active patterns and the first insulating layer using the first mask patterns and the second mask pattern.

Claim (Index 3):
The method of  claim 2 , wherein the first etching process forms a rounded corner in the partly defined active region beneath a corner, among those of the first mask patterns and the second mask pattern, where the second mask pattern does not overlap either of the first mask patterns as viewed in the plan view, and\n further comprising: forming a cutting mask having a mask pattern corresponding to parts of a PMOS region and an NMOS region; forming a third trench that defines the PMOS region and the NMOS region along with the second trench by executing a second etching process that etches the partly defined active region and removes the rounded corner therefrom, using the cutting mask, the PMOS region and the NMOS region containing respective ones of the active patterns; and forming a third insulating layer filling the third trench.
