Abstract

A method for manufacturing a microstructure comprises the steps of forming positive type resist layer (PMMA) on a base plate having heater formed thereon; forming positive type resist layer (PMIPK) on the aforesaid positive type resist layer; exposing the positive type resist layer on the upper layer to ionizing radiation of the wavelength region that gives decomposition reaction to the positive type resist layer (PMIPK) for the formation of a designated pattern by development; exposing the positive type resist layer on the lower layer to ionizing radiation of the wavelength region that givens decomposition reaction to the positive type resist layer (PMMA) for the formation of a designated pattern by development; and coating photosensitive resin film having adhesive property on the resist pattern formed by the positive type resist layer (PMMA) and positive type resist layer (PMIPK); and then, dissolving the resist pattern to be removed after the resin film having adhesive property is hardened.
