DRY PROCESS FOR FORMING METAL PATTERNS ON A SURFACE

摘要

The process for forming a desired metal pattern on a substrate (35) comprises forming a mask of a thermally depolymerizable polymer (40) on the substrate (35) with a pattern of openings (70) complementary to the desired metal pattern, blanket coating the substrate (35) and the mask (40) with a metal (60), heating the substrate (35) to depolymerize the depolymerizable polymer (40), cooling the surface of the metal (60) to thereby delaminate the metal coated in areas where thermally depolymerizable polymer (40) is present, removing the delaminated metal where necessary, and optionally plasma etching the depolymerized polymer, if residue thereof remains, to remove the same from said substrate.
