Patent ID: 7498647

Claim:
A packaged microelectronic imaging die, comprising: a microelectronic substrate having a first side, a second side opposite the first side, an image sensor, and an integrated circuit electrically coupled to the image sensor; a terminal carried by the substrate and electrically coupled to the integrated circuit; and an electrically conductive interconnect extending through at least a portion of the substrate and contacting the terminal, wherein the interconnect does not extend completely through the terminal; wherein the substrate includes a hole extending from the second side of the substrate to the terminal, and wherein the hole does not extend through the terminal; and the interconnect comprises: a dielectric liner disposed within at least a portion of the hole and in contact with the substrate, a first conductive layer disposed over at least a portion of the dielectric liner, a second conductive layer disposed over at least a portion of the first conductive layer, and a conductive fill material disposed in the hole over at least a portion of the second conductive layer and electrically coupled to the terminal.
