发明名称 Resist material, resist pattern and forming method for the same, and a semiconductor device and manufacturing method for the same
摘要 The resist material contains a photo-acid generator having an absorption peak to exposure light having a wavelength of less than 300 nm, and a second photo-acid generator having an absorption peak to exposure light having a wavelength of 300 nm or more. The method for forming a resist pattern comprises a step for selectively exposing which exposes a coating film of the resist material to an exposure light having a wavelength of less than 300 nm, and a step for selectively exposing by using an exposure light having a wavelength of 300 nm or more. The semiconductor device comprises a pattern formed by the resist pattern. The method for forming a semiconductor device comprises a step for forming a resist pattern on an underlying layer by the aforementioned manufacturing method, and a step for patterning the underlying layer by etching using the resist pattern as a mask.
