Abstract:
A semiconductor device structure, comprising:a region of electrically insulating material; a region of electrically conducting material; and a barrier film between the region of electrically insulating material and the region of electrically conducting material, the barrier film comprising a compound including nitrogen and at least one of titanium or tantalum, nitrogen in a concentration that varies within the barrier film, and oxygen in a concentration that varies within the barrier film; wherein the nitrogen content of the barrier film varies from about 30% to about 60% in atomic percent in the vicinity of the region of insulating material to about 0% in the vicinity of the region of an electrically conducting material; and wherein the oxygen content of the barrier film varies from about 1% to about 5% in the vicinity of the region of insulating material to about 0% in atomic percent in the vicinity of the region of electrically conducting material.
