Patent ID: 8084866

Claim:
A microelectronic device set comprising: a first microelectronic device having: a first die with a first integrated circuit and a first bond-pad electrically coupled to the first integrated circuit, the first die further including a tapered passage extending completely through the first die and the first bond-pad; and a conductive interconnect deposited in the tapered passage, the conductive interconnect including a first conductive material deposited in a first portion of the tapered passage to form a conductive plug in contact with the first bond-pad and having a boundary in the tapered passage, and a second conductive material deposited in a second portion of the tapered passage in contact with inner walls of the tapered passage and the boundary of the conductive plug to at least generally fill the tapered passage; and at least a second microelectronic device having a second die with a second integrated circuit and a second bond-pad electrically coupled to the second integrated circuit, wherein the second bond-pad is electrically coupled to the conductive interconnect of the first microelectronic device.
