A technique is described whereby a chemical coating process provides electrical insulation properties to devices, such as integrated circuit packages, without a significant increase in thermal resistance. This allows any thermal contact material to be used, regardless of its electrical characteristics. With the ever increasing integrated circuit (IC) densities, there is an increasing demand for improved cooling systems. High performance cooling requires excellent thermal contact, which is correlated with good electrical contact. For good heat diffusion through solid components, cooling systems typically use metal components. For good thermal contact between solids, low temperature fusible metal alloy is generally employed at the interface.
