Abstract:
An interconnect apparatus and a method of forming the interconnect apparatus is provided. Two substrates, such as wafers, dies, or a wafer and a die, are bonded together. A first mask is used to form a first opening extending partially to an interconnect formed on the first wafer. A dielectric liner is formed, and then another etch process is performed using the same mask. The etch process continues to expose interconnects formed on the first substrate and the second substrate. The opening is filled with a conductive material to form a conductive plug.

Claim (Index 9):
An apparatus comprising:\n a first semiconductor chip having a first substrate and one or more first dielectric layers on a first surface of the first substrate, a first conductive feature being in the one or more first dielectric layers; a second semiconductor chip having a second substrate and one or more second dielectric layers on a first surface of the second substrate, a second conductive feature being in the one or more second dielectric layers, an outermost first dielectric layer of the one or more first dielectric layers being bonded to an outermost second dielectric layer of the one or more second dielectric layers; a conductive plug extending from a second surface of the first substrate to the second conductive feature; and a first liner interposed between the conductive plug and the first substrate, the first liner extending from a second surface of the first substrate partially to the first conductive feature, the first liner not extending to the first conductive feature, a width of the conductive plug extending through the first liner being greater than a width of the conductive plug extending from the first conductive feature to the second conductive feature.
