Abstract: A film forming method includes preparing a substrate having an amorphous silicon film on a surface thereof, diffusing nickel into the amorphous silicon film by supplying a nickel source gas to the amorphous silicon film, and forming a polycrystalline silicon film by heating the amorphous silicon film, and crystallizing the amorphous silicon film by metal-induced lateral crystallization using the nickel diffused in the amorphous silicon film as a nucleus.

Abstract: An aqueous crosslinkable resin composition suitable as surface coating material, under coating material, impregnation treating material or binder and having excellent properties such as solvent resistance, water resistance, thermal discoloration resistance, long pot life and no generation of formaldehyde, which comprises (A) an acrylic copolymer of a carboxyl group-containing monomer, an alkyl acrylate or methacrylate, and optionally a monomer having a basic nitrogen atom and/or other copolymerizable vinyl monomers, wherein at least 0.5 % by mole of carboxyl groups is neutralized with an imidazole compound, and (B) an epoxy resin, the equivalent ratio of the carboxyl group of (A) to the epoxy group of (B) being from 1/3 to 3/1.
