Abstract:
1. An integrated circuit package comprising: a semiconductor die having a first side and an opposite second side; a metallization layer coupled to the first side, the metallization layer including an adhesion layer and a diffusion layer having a first side and a second side, and the adhesion layer being disposed between the second side of the diffusion layer and the first side of the semiconductor die to prevent the adhesion layer from reacting with a material disposed on a first side of the diffusion layer; an integrated heat spreader; a post-reaction thermal interface material, including an intermetallic compound comprising an alloy formed from copper and a selected one of tin and indium, said thermal interface material coupling a die side of the integrated heat spreader to the metallization layer; and a substrate having a surface, the semiconductor die second side coupled to the surface.
