Abstract
A method for forming a conductive contact having an atomically flat interface is disclosed. A layer containing cobalt and titanium is deposited on a silicon substrate and the resulting structure annealed in a nitrogen containing atmosphere at about 500.degree. C. to about 700.degree. C. A conductive material is deposited on top of the structure formed on anneal. A flat interface, which prevents diffusion of conductive materials into the underlying silicon substrate is formed. The method can be used to form contacts for very small devices and shallow junctions, such as are required for ULSI shallow junctions.
