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 16):
A method of manufacturing a semiconductor device comprising:\n forming, in a semiconductor substrate, first trenches that delimit parallel linear active patterns spaced apart from one another in a first direction and each extending longitudinally in a second direction perpendicular to the first direction; forming a first insulating layer filling the first trenches; executing a first patterning process to form at least one first mask pattern and executing a second patterning process, discrete from the first patterning process, to form a second mask pattern before or after the at least one first mask pattern is formed, wherein each said at least one first mask pattern lies over at least part of a respective one of the active patterns and has a side extending in the second direction parallel to the active patterns, and the second mask pattern has a side extending in the first direction and which meets the side of each said at least one first mask pattern as viewed in plan, whereby the side of the second mask pattern subtends a right angle with the side of each said at least one first mask pattern as viewed in a plan view; executing a first etching process, using the first and second mask patterns as an etch mask, to remove sections of the active patterns and the first insulating layer and thereby form a second trench; and forming a second insulating layer filling the second trench.
