Abstract
PURPOSE:To reduce a contact resistance value by a method wherein an interlayer insulating film, a titanium layer and a tungsten silicide layer formed along the surface of the titanium layer are formed on a semiconductor so that the layer is hard to exfoliate. CONSTITUTION:After an interlayer insulating film 2 has been formed on a semiconductor layer 1, a contact hole 3 is made in the interlayer insulating film 2; a titanium layer 4 is formed on the semiconductor layer 1 inside the contact hole 3 and on the interlayer insulating film 2 by a magnetron sputtering operation. Then a tungsten silicide layer 5 is formed on the titanium layer 4 by a low-pressure CVD operation. During this process, the contact hole 3 is filled completely with the tungsten silicide layer 5. The tungsten silicide layer 5 and the titanium layer 4 are etched back selectively by an RIE operation; the interlayer insulating film 2 is exposed. By this setup, the tungsten silicide layer is hard to exfoliate; a resistance value can be reduced.
