Abstract
A method of manufacturing epitaxial titanium silicide in a metal silicide processing has a lower than usual processing temperature requirement, and is therefore suitable for use in the manufacturing of integrated circuits. The epitaxial titanium silicide so formed is made without a grain boundary and is thus capable of lowering the electrical resistance of the titanium silicide. First, a silicon substrate with an exposed crystalline silicon layer on the surface is provided. Then a titanium layer and a titanium nitride layer are sequentially formed. Finally, using a rapid thermal processing, an epitaxial titanium silicide layer is formed.
