Zusammenfassung:	According to an exemplary embodiment, a method of forming a substrate pattern having an isolated region and a dense region is provided. The method includes the following operations: forming a first photoresist layer over the substrate; exposing the first photoresist layer through a first mask corresponding to the isolated region; developing the first photoresist layer to form a first pattern; forming a second photoresist layer over the substrate and the first pattern; exposing the second photoresist layer through a second mask corresponding to the substrate pattern; developing the second photoresist layer to form a second pattern; and etching the first pattern and the substrate to form the substrate pattern in the isolated region and the dense region.
