Abstract
A conductive interface includes a first conductor having a recessed area in least one surface. A dielectric layer has a trench positioned over the first conductor. A nitridized layer is formed on a top surface of the first conductor around the recessed area, to a depth on the first conductor that is shallower than a depth of the recessed area. A second conductor is formed in the trench and the recessed area to form a conductive contact with the first conductor.
