Patent ID: 8148204

Claim:
A method for producing a circuit connection structure comprising the steps of: (a) modifying a surface of a semiconductor substrate on which a heat resistant resin film and a first circuit electrode are disposed, by giving a plasma treatment to the semiconductor substrate, using a nitrogen-based gas containing at least one component selected from the group consisting of nitrogen, ammonia and hydrazine, wherein the plasma treatment produces an amide group or an amino group on a surface of the heat resistant resin film; (b) arranging the semiconductor substrate whose surface has been modified and a circuit member having a second circuit electrode to be opposed to the first circuit electrode so that the first circuit electrode is opposed to the second circuit electrode with a circuit adhesive member interposed therebetween, wherein the circuit adhesive member is an adhesive film or an adhesive paste that contains a component selected from the group consisting of an epoxy-based resin and an acrylic resin; and (c) bonding the semiconductor substrate and the circuit member with pressure to adhere the semiconductor substrate and the circuit member for establishing mutual electrical connection between the first circuit electrode and the second circuit electrode, wherein the heat resistant resin film is a film comprising: i. a polymer of at least one component selected from the group consisting of polyamide, polyimide, polyamideimide, polybenzoxazole, polybenzimidazole and benzocyclobutene; or ii. a copolymer of at least two components selected from the group consisting of polyamide, polyimide, polyamideimide, polybenzoxazole, polybenzimidazole and benzocyclobutene; or iii. at least one precursor of the polymer.
