Complex ICs (CPUs and the like) are moving away from aluminum interconnects to copper, since copper conducts better and would generate less heat. I understand that silver and gold are better conductors than copper. While gold is rather expensive, silver is reasonably priced per ounce, and I do not think a chip would use more than an ounce or two. Given that they find a way of modifying the IC production process to work with it, is it possible that we will see a shift to silver-interconnect ICs? Or is there a problem with it that I don't understand? Also, are there any better conductors than copper/silver/gold that could possibly be used instead?
