Abstract:
Provided is a method of fabricating a semiconductor device. The method includes forming an anti-reflection layer on a lower layer, forming photoresist patterns on the anti-reflection layer, forming protection patterns to cover the photoresist patterns, respectively, etching the anti-reflection layer using the photoresist patterns covered with the protection patterns as an etch mask to form anti-reflection patterns, forming spacers to cover sidewalls of the anti-reflection patterns, and removing the anti-reflection patterns.
