Abstract:
A method for forming a contact interface, comprising:providing a substrate including semiconductor material with at least one contact comprising semiconductor material protruding from said substrate; forming a first layer comprising dielectric material over said semiconductor material and said at least one contact; forming a second layer comprising polysilicon over said first layer and over at least a portion of a lateral surface of said at least one contact; forming a third layer comprising barrier material over said second layer; exposing at least a portion of said second layer located over said at least one contact, including at least a portion of said second layer located over at least said portion of said lateral surface of said at least one contact through at least said third layer; disposing electrically conductive silicidable material into contact with at least said portion of said second layer exposed through at least said third layer; and forming a silicide contact at least an interface between said electrically conductive silicidable material and said second layer.
