In a clean room, after conducting a surface treatment on the surface of a semiconductor substrate with 4-trimethylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a chemically amplified resist, thereby forming a first resist film. Then, the first resist film is successively subjected to exposure, PEB and development, thereby forming a first resist pattern of the chemically amplified resist. Next, in the same clean room, after conducting a surface treatment on the surface of the semiconductor substrate with 4-dimethyl-n-hexylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a non-chemically amplified resist, thereby forming a second resist film. Then, the second resist film is successively subjected to the exposure, the PEB and the development, thereby forming a second resist pattern of the non-chemically amplified resist. |
