METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE |
摘要 |
A method of manufacturing a semiconductor device according to one embodiment, includes: forming a first mask material film on a workpiece film formed on a semiconductor substrate; forming a resist pattern on the first mask material film; forming a second mask material film having a desired film thickness on the first mask material film so as to cover the resist pattern; carrying out etchback of the second mask material film so as to expose the resist pattern and the first mask material film; processing the resist pattern and the first mask material film simultaneously which are exposed, while leaving the second mask material film of which etchback is carried out; and processing the workpiece film which exposes under the first mask material film.
