Title: Pattern forming method
Inventor: ENDO MASATAKA
IPC: G03F7/095
Filed: 1988-10-06
Abstract: PURPOSE:To form patterns having good shapes by forming a resist on a substrate, then forming a film having a melamine compd., and subjecting the film to selective exposing, full-surface exposing with UV rays and developing, thereby forming the resist patterns. CONSTITUTION:After the resist is formed on the substrate, the film having the melamine compd. is formed thereon and is subjected to exposing, full-surface exposing with UV rays and developing, by which the patterns are formed. A film consisting of a compd. having an azide group and sulfonic acid group and a water soluble resin may be used in place of the film consisting of the melamine compd. This compd. is decreased in the transmittance of a UV region by far UV light or excimer laser light such as ArF, KrF and XeCl in particular. For example, the absorption at about 436nm is increased in the part exposed with the excimer laser and the transmittance at about 436nm is high in the unexposed part; therefore, the film of the melamine compd. serves as a contact mask at the time of the later full-surface exposing at 436nm. Spreading of the light is obviated and the resulted pattern have the shape of a high aspect ratio. The fine resist patterns having the good shape are thus obtd.
