Abstract:
A method of fabricating a semiconductor interconnect structure by providing a semiconductor structure with a dielectric layer with and an embedded electrically conductive structure. A dielectric capping layer and a metal capping layer separating a second dielectric layer located above the first dielectric layer. The segment of metal capping layer covers at least a portion of a top surface of the first electrically conductive structure. Exposing parts of both the first electrically conductive structure and the dielectric capping layer by forming an opening in the second dielectric layer and the metal capping layer. Forming a second electrically conductive structure in the opening, such that (i) the second electrically conductive structure is located over part of the dielectric capping layer, and (ii) the second electrically conductive structure is in electrical contact with the first electrically conductive structure.

Claim (Index 1):
A method of fabricating a semiconductor interconnect structure, the method comprising:\n providing a semiconductor structure including a first dielectric layer having a first electrically conductive structure embedded therein, a second dielectric layer located above the first dielectric layer, the second dielectric layer and the first dielectric layer having a segment of a dielectric capping layer located therebetween, and a segment of a metal capping layer located therebetween, the segment of metal capping layer covering at least a portion of a top surface of the first electrically conductive structure; forming an opening in the second dielectric layer and the metal capping layer, thereby exposing at least a portion of the first electrically conductive structure and a portion of the dielectric capping layer; and forming a second electrically conductive structure in the opening, such that a first bottom portion of the second electrically conductive structure is located over a portion of the dielectric capping layer, and such that a second bottom portion of the second electrically conductive structure is in electrical contact with the portion of the first electrically conductive structure.
