Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
A process for increasing the adhesion of an organic resin material to a metal or silicon containing substrate, said process comprising the steps of: (1) providing a vapor of an unsaturated organophosphine, (2) introducing said organophosphine vapor into a reaction chamber, (3) subjecting said organophosphine vapor to radio energy discharge, so as to deposit a film of polymerized organophosphine on said substrate, and (4) applying a coating of an organic resin on top of said film of polymerized organophosphine.
Claim 2
Dependent Claim
79 words
A process for increasing the adhesion of an organic resin material to a metal or silicon containing substrate, said process comprising the steps of: (1) providing a vapor of an unsaturated organophosphine, (2) introducing said organophosphine vapor into a reaction chamber, (3) subjecting said organophosphine vapor to radio energy discharge, so as to deposit a film of polymerized organophosphine on said substrate, and (4) applying a coating of an organic resin on top of said film of polymerized organophosphine.
Claim 3
Dependent Claim
13 words
A process as claimed in claim 1 wherein the unsaturated organophosphine is trivinylphosphine.
Claim 4
Dependent Claim
21 words
A process as claimed in claim 1 wherein the film of polymerized organophosphine is from 400 to 600 A in thickness.
Claim 5
Dependent Claim
17 words
A process as claimed in claim 1 wherein the substrate is silicon, silicon dioxide or silicon nitride.
Claim 6
Dependent Claim
18 words
A process as claimed in claim 1 wherein the coating of the organic resin is applied by spin-coating.
