Abstract:
An interconnect apparatus and a method of forming the interconnect apparatus is provided. Two integrated circuits are bonded together. A first opening is formed through one of the substrates. A multi-layer dielectric film is formed along sidewalls and a bottom of the first opening. A second opening is formed extending from the first opening to pads in the integrated circuits. A dielectric liner is formed, and the opening is filled with a conductive material to form a conductive plug.

Claim (Index 1):
An apparatus comprising:\n a first semiconductor chip comprising a first substrate, a plurality of first dielectric layers over the first substrate, and a plurality of first metal lines in the plurality of first dielectric layers; a second semiconductor chip having a second surface bonded to a first surface of the first semiconductor chip, wherein the second semiconductor chip comprises a second substrate, a plurality of second dielectric layers over the second substrate and a plurality of second metal lines in the plurality of second dielectric layers; a conductive plug comprising a first portion having a first width and a second portion having a second width, the second width being less than the first width, the first portion extending through the first substrate, the second portion extending through the plurality of first dielectric layers and into the plurality of second dielectric layers; and a plurality of liners interposed between the conductive plug and the first substrate, the plurality of liners extending along a bottom of the first portion of the conductive plug, at least one of the plurality of liners not extending between the conductive plug and the plurality of first dielectric layers, topmost surfaces of the plurality of liners being level with a topmost surface of the conductive plug.
