Abstract
A multichip IC module having dice and substrates coplanarly bonded therein. After the dice are aligned into die openings of the substrate, a glass slurry is applied and the module is fired to solidify the glass. Because of shrinkage of the glass slurry firing, a groove results between the dice and the substrate. To fill on this groove, a polyimide or like film is adhered and then pressued and cured on the surface of the dice and substrate. This film is used as a base for interconnect lines.
