In one aspect of the present invention, a method of manufacturing a semiconductor device may include forming a first film on an amorphous silicon layer to be patterned, the first film and the amorphous film having a line-and-space ratio of approximately 3:1, sliming down, after processing the first film, a line portion of the pattern from both longitudinal sides of the line portion until the width of the line portion is reduced to approximately one third, reforming a part of the amorphous silicon layer where the first film is not provided such that reformed part has different etching ratio, and removing the first film and the amorphous silicon layer other than reformed part.
