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 20):
The method of  claim 16 , wherein the forming of the at least one first mask pattern comprises forming first mask patterns that are spaced apart from each other in the first direction and each have the shape of a rectilinear polygon as viewed in the plan view, and\n the first etch process forms a partially defined active region having a respective rounded corner beneath each of at least one of the corners of the first mask patterns, and further comprising forming a first cutting mask having an opening or openings therethrough over the at least one rounded corner; and executing a second etch process using the first cutting mask as an etch mask to remove each said rounded corner; forming a second cutting mask having an opening therethrough over at least one of the active patterns centrally among the active patterns in the first direction; and executing a third etch process using the second cutting mask as an etch mask to divide the partially defined active region and thereby form a third trench which together with the second trench delimits two active regions each in the shape of a rectilinear polygon having more than four sides.
