Abstract:
A semiconductor metallurgy includes a ratio of germanium and palladium that provides low contact resistance to both n-type material and p-type material. The metallurgy allows for a contact that does not include gold and is compatible with mass-production CMOS techniques. The ratio of germanium and palladium can be achieved by stacking layers of the materials and annealing the stack, or simultaneously depositing the germanium and palladium on the material where the contact is to be manufactured.
