Abstract:
A pattern-forming method which comprises the following steps:(1) laminating an actinic ray-sensitive coating film layer onto the surface of an insulating film-forming resin layer applied onto a substrate; (2) irradiating directly or through a photomask an actinic ray or heat wave thereonto so as to obtain a predetermined pattern; (3) subjecting the actinic ray-sensitive coating film layer to a developing treatment to form a predetermined resist pattern coating film consisting of the actinic ray-sensitive coating film layer with an exposed area of the insulating film forming resin layer; (4) and subjecting the exposed area of the insulating film-forming resin layer to a liquid developing treatment, thereby removing the exposed area of the insulating film-forming resin layer; and (5) removing the predetermined resist pattern coating film consisting of the actinic ray-sensitive coating film layer to form a predetermined insulating film pattern on the substrate, the insulating film-forming resin layer containing a resin having a glass transition temperature in the range of 15 to 250Â° C., provided that the glass transition temperature of the resin is higher than a developing temperature in the range of 10 to 80Â° C.
