    摘要: A method of forming a protection layer on a photoresist pattern and a method of forming a fine pattern using the same are provided. A photoresist layer may be formed on a substrate. Exposure regions and non-exposure regions may be defined in the photoresist layer by an exposure process. A reactive material layer may be formed on the photoresist layer having the exposure regions. A protection layer may be formed on the exposure regions by the reactive material layer reacting via a chemical attachment process. The non-exposure regions and the reactive material layer that remains after the reaction may be removed by a development process to form photoresist patterns. The substrate may be etched using the protection layer and the photoresist patterns as etching masks.
