Claim:
1. A semiconductor device manufacturing method comprising: preparing a first substrate above which a first film having a photosensitive film is formed; supplying a first washing liquid to an entire top surface of the first film before using an exposure apparatus to emit energy rays to the photosensitive film, the photosensitive film being a chemically amplified resist film which contains an optical acid generating material; emitting energy rays to the photosensitive film using the exposure apparatus after the supplying of the first washing liquid to the entire top surface of the first film; and developing the photosensitive film in order to form a photosensitive film pattern, wherein a planarization of the photosensitive film above the first substrate is unchanged during the supplying the first washing liquid to the entire top surface of the first film.
