Abstract:
1. A method of forming a bonding film and using same for connecting a die to a contacting surface by bonding and creating electrical or thermal contact between the die and the contacting surface, comprising the steps of: growing a plurality of nanostructures on a conductive substrate in such a way that said nanostructures extend perpendicularly to said conductive substrate; coating said nanostructures using a carrier material to form said bonding film comprising said plurality of nanostructures and said carrier material on said conductive substrate, said carrier material being selected such that said bonding film can be made adhesive to adhere to said die and to said contacting surface after removal from said substrate; dicing said bonding film to create individual bonding pads having a size being adapted to said die; lifting said bonding pads from said conductive substrate; and connecting the die to the contacting surface by placing one of said bonding pads between the die and the contacting surface to create electrical or thermal contacts between the die and the contacting surface via the plurality of nanostructures, wherein connecting the die to the contacting surface further includes curing the bonding pad, wherein curing the bonding pad causes the die to become bonded to the bonding pad and the bonding pad to become bonded to the contacting surface, the bonding creating said electrical or thermal contacts between the die and the contacting surface via the plurality of nanostructures.
