Abstract
A method for manufacturing a multichip module deposited substrate board utilizing alternating layers of high density thin-film metal and either preimidized or non-preimidized organic polymer insulating material wherein the insulating material is cured during manufacture using either ultraviolet radiation, ion beam radiation or electron beam radiation. This method eliminates subjecting the in-process substrate board to temperatures in excess of the recrystalization temperature of the thin-film metal, thereby eliminating the source of warpage and metal interdiffusion and corrosion at the metal to insulating material interface. This process enables successful manufacture of large format multichip module deposited substrate boards in sizes up to approximately 24 inches square.
