Title: Formation of resist pattern
Inventor: MATSUI HIROYUKI
IPC: H05K3/06
Filed: 1989-07-24
Abstract: PURPOSE:To form fine resist patterns with a simple device and process by interposing a curable resin between a master plate and a substrate, pressurizing and curing the resin, and stripping the master plate, then removing the recesses of the cured resin. CONSTITUTION:The master plate 1 provided with recesses 2 of desired pattern shapes is subjected to a release treatment at need and the ionization radiation curing or thermosetting resin 4 is dropped thereon. A substrate 3 is superposed thereon in such a manner that the electrode layer 13 side thereof faces the master plate and the plates are pressurized by pressing rolls 11 or pressurizing plates to spread the resin 4 over the entire surface. The resin 4 is then cured by irradiation with UV rays, etc., or heating and the plate 1 is stripped. A rugged relief layer 6 consisting of the cured resin is thus formed on the substrate 3. The entire surface is thereafter etched uniformly over the entire surface to completely remove the cured resin of the recesses 8 of the relief layer. The resist layer 7 consisting of the remaining projecting parts is thus formed.
