Abstract:
A method of fabricating a mask for a semiconductor device, comprising:applying a first photoresist film on a silicon wafer;sequentially forming a first insulation film, a second insulation film, and a second photoresist film on the first photoresist film;patterning the second photoresist film by an etching process;patterning the first and second insulation films by etching using the patterned second photoresist film as a mask;patterning the first photoresist film by etching using the patterned first and second insulation films, and the patterned second photoresist film as a mask;removing the second photoresist film;etching a predetermined portion of the first insulation film;depositing a metal on the silicon wafer and on at least one of the first photoresist film, the first insulation film having the predetermined etched portion, and the second insulation film; andremoving the first photoresist film, and the first and second insulation films from the silicon wafer.
