Abstract:
1. A pattern forming method comprising: forming a spin on dielectric film above a substrate; washing an entire top surface of the spin on dielectric film by using a washing liquid, the washing liquid being supplied to a center of the substrate from a nozzle; drying the surface of the spin on dielectric film after the washing; forming a photosensitive film on the surface of the spin on dielectric film; emitting energy rays to the photosensitive film in order to form a latent image on the photosensitive film; developing the photosensitive film in order to form a photosensitive film pattern which corresponds to the latent image; and processing the spin on dielectric film with the photosensitive film pattern serving as a mask, wherein a planarization of the entire top surface of the substrate is unchanged before and after the washing.
