Abstract
A method of forming a pattern structure includes forming a thin film pattern on a substrate, the thin film pattern including depression portions with first bottom widths, forming a protection layer on the thin film pattern by implanting ions into the thin film pattern, and etching a lower portion of the thin film pattern selectively using the protection layer as a mask to increase the first bottom widths of the depression portions into second bottom widths.
