An inventive composition and process for formation of a conductive bonding film are disclosed. The invention combines adhesive bonding sheet technologies (e.g. die attach films, or DAFs) with the electrical and thermal conductivity performance of transient liquid phase sintered paste compositions. The invention films are characterized by high bulk thermal and electrical conductivity within the film as well as low and stable thermal and electrical resistance at the interfaces between the inventive film and metallized adherends.
