Patent ID: 7205096

Claim:
A method for forming a metal pattern comprising the steps of: (i) coating a photosensitive compound represented by Formula 1 below on a substrate to form a photosensitive film; (ii) selectively exposing the photosensitive film to light in the presence of a photoacid generator to form a latent pattern for crystal growth having a free carboxyl group; and (iii) treating the latent pattern for crystal growth with a nanometallic solution in which metal nanocrystals are formed to grow the metal nanocrystals on the latent pattern: wherein represents the backbone chain of a copolymer constituting the photosensitive compound; A and B, which is identical to or different from each other, are polymer units selected from the group consisting of polyethylenes, polyesters, polycarbonates, polyvinylalcohols, polyvinylbutyrals, polyacetals, polyarylates, polyamides, polyamideimides, polyetherimides, polyphenyleneethers, polyphenylenesulfides, polyethersulfones, polyetherketones, polyphthalamides, polyethernitriles, polybenzimidazoles, polycarbodiimides, polysiloxanes, polymethylmethacrylates, polymethacrylamides, nitrile rubbers, acrylic rubbers, polyethylenetetrafluorides, epoxy resins, phenol resins, melamine resins, urea resins, cellulose resins, polybutenes, polypentenes, ethylene-propylene copolymers, ethylene-butenediene copolymers, polybutadienes, polyisoprenes, ethylene-propylenediene copolymers, butyl rubbers, polymethylpentenes, polystyrenes, styrene-butadiene copolymers, hydrogenated styrene-butadien copolymers, polystyrene-hydrogenated polyisoprenes, and hydrogenated polybutadienes; R 1 is a C 2˜6 alkylene group, cyclohexyl, or phenyl; the sum of m and n is 1; and n is between 0.1 and 0.9.
