Abstract
A process for forming a desired metal pattern on a substrate which comprises, forming a mask of a thermally depolymerizable polymer on the substrate with a pattern of openings complementary to the desired metal pattern, blanket coating the substrate and the mask with a metal, heating the substrate to depolymerize the depolymerizable polymer, cooling the surface of the metal to thereby delaminate the metal coated in areas where thermally depolymerizable polymer is present, removing the delaminated metal where necessary, and optionally plasma ashing the depolymerized polymer, if residue thereof remains, to remove the same from said substrate.
