Abstract:
A photomask layout includes: a substrate region; a lower stepped region at a region of the substrate region; and a pattern region at least partially crossing the lower stepped region and including at least one notch portion at an area overlapping the lower stepped region. A method of forming a pattern is also provided.

Claim (Index 1):
A method of forming a pattern, the method comprising:\n forming a lower stepped pattern on a substrate such that a sidewall of the lower stepped pattern extends in a lengthwise direction of the lower stepped pattern; forming an upper pattern layer on the substrate, the upper pattern layer covering the lower stepped pattern; forming a photoresist layer on the upper pattern layer; partially removing the photoresist layer using a photomask to form a photoresist pattern, the photomask including a light-shielding portion that at least partially crosses the lower stepped pattern and includes a recessed portion that is recessed toward the lengthwise direction of the lower stepped pattern; and partially removing the upper pattern layer using the photoresist pattern to form an upper pattern, wherein an inclined region is defined by the sidewall of the lower stepped pattern, and the recessed portion at least partially overlaps a portion under which the inclined region is located.
