Multilayer hybrid integrated circuit

Claim 2

A multilayer circuit device comprising a substrate having a metallized pattern thereon and a plurality of polymeric dielectric film layers each having a metallized circuit pattern thereon with metallized microvias interconnecting the metallized patterns of one layer with that of at least one other metallized layer thereunder, said polymeric dielectric layer being formed from a photodefinable triazine base mixture including a photosensitive acrylate moiety wherein the triazine comprises from 40-65 weight percent of the mixture.

Claim 3

The device of claim 1, wherein the triazine mixture comprises 40 to 65 weight percent triazine, 0 to 30 weight percent rubber resin, 0 to 50 weight percent of a member selected from the group consisting of an epoxy acrylate hybrid resin and a combination comprising an epoxy resin and an acrylate resin wherein when the percent of both the epoxy acrylate hybrid and acrylate resin in the triazine mixture is zero, the acrylate moiety is on the triazine molecule, 0 to 12 weight percent of a hardener, 0 to 8 weight percent of a crosslinking agent, 0 to 5 weight percent of a coupling agent and 1/2 to 3 weight percent of a photoinitiator.

Claim 4

The device as set forth in claim 2, wherein the rubber resin is an acrylonitrile butadiene rubber, the epoxy and acrylate is in the form of a hybrid epoxy-acrylate resin which is carboxy or vinyl terminated and the coupling agent is a silane coupling agent.

Claim 5

The device recited in claim 3 further including N-vinylpyrrolidone as the hardener, and 2,2-dimethoxy-2-phenylacetophenone as the photoinitiator.

Claim 6

The device as recited in claim 2 further including a surfactant and a copper chelate thermostabilizer.

Claim 7
