Abstract

A first conductive pad is connected to a second conductive pad by using a post-transition metal and a nanoporous metal. An example of the post-transition metal is indium. An example of the nanoporous metal is nanoporous gold. A block of the post-transition metal is formed on the first conductive pad. The block of the post-transition metal is coated with a layer of anti-corrosion material. A block of the nanoporous metal is formed on the second conductive pad. The block of the post-transition metal and the block of the nanoporous metal are thermal compressed to form an alloy between the first conductive pad and the second conductive pad.
