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 2):
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 the recessed portion of the light-shielding portion is formed to overlap an intersection region of the light-shielding portion and the lower stepped pattern.
