Claim 8:
9. The method of claim 1, comprising:
providing a second dielectric structure over the second conductive pattern, wherein the second dielectric structure includes second dielectric structure openings that expose top side portions of the second conductive pattern;
providing a second conductive seed layer on the second dielectric structure, wherein the second conductive seed layer conforms to the second dielectric structure openings and contacts the exposed top side portions of the second conductive pattern;
oxidizing exposed surfaces of the second conductive seed layer to form a second oxidized barrier that includes second oxidized barrier lateral portions formed from exposed lateral sidewalls of the second conductive seed layer along lateral sidewalls of the second dielectric structure openings; and
providing a third conductive pattern on the second oxidize barrier and in the second dielectric structure openings such that the third conductive pattern is electrically coupled to the second conductive pattern via the exposed top side portions of the second conductive pattern.
