发明名称 Device having dual etch stop liner and reformed silicide layer and related methods
摘要 The present invention provides a semiconductor device having dual silicon nitride liners and a reformed silicide layer and related methods for the manufacture of such a device. The reformed silicide layer has a thickness and resistance substantially similar to a silicide layer not exposed to the formation of the dual silicon nitride liners. A first aspect of the invention provides a method for use in the manufacture of a semiconductor device comprising the steps of applying a first silicon nitride liner to a silicide layer, removing a portion of the first silicon nitride liner, reforming a portion of the silicide layer removed during the removal step, and applying a second silicon nitride liner to the silicide layer.
