Abstract:
A method of forming a titanium silicide region on a semiconductor device, said method comprising the steps of:providing a silicon layer;forming a titanium layer over the silicon layer;heating the silicon layer and the titanium layer to a first temperature so that the silicon layer and titanium react to form a titanium silicide region of a first type; andapplying an external force to said titanium silicide region of a first type sufficient to overcome an opposite force to be developed by conversion of said titanium silicide region of a first type to a titanium silicide region of a second type and simultaneously heating the titanium silicide region of a first type to a higher temperature to convert said titanium silicide of a first type to said titanium silicide of a second type while said conversion provides said opposite force, force wherein said external force is applied to said titanium silicide by warping the semiconductor device on a susceptor with a radius of curvature.
