Abstract:
1. A method for connecting an integrated circuit to a substrate, the method comprising providing a first electrical contact structure on the integrated circuit, providing a second electrical contact structure on the substrate, at least one of the first and second electrical contact structures having an elastic elevation thereon, attaching the integrated circuit to a frame structure, the frame structure including a lateral subregion, the lateral subregion at least partially surrounding the integrated circuit and not in contact with a surface of said substrate when said current path is formed forming a current path between the first electrical contact structure and the second electrical contact structure, and attaching the frame structure to the substrate, thereby compressing the elastic elevation; wherein attaching the frame structure includes: applying heat to bring said frame structure in contact with said substrate, such that upon heating, said subregion expands and touches a surface of said substrate, and upon cooling, said subregion remains attached to the surface of said substrate.
