Abstract:
1. A microelectronic imager comprising: an optical device formed from an optical device workpiece, the optical device comprising an optical element for transmitting light onto an image sensor aligned with the optical element; an imaging unit, the imaging unit comprising the image sensor, an integrated circuit formed in a substrate, and a plurality of external contacts comprising a terminal disposed on a first surface of the substrate, a contact pad disposed on a second surface of the substrate opposite the first surface and an interconnect electrically coupling the terminal to the contact pad, wherein the interconnect extends completely through the terminal and the substrate wherein the terminal has an inner surface and an outer portion and wherein the interconnect is formed in a via that is formed through and therefore surrounded by the inner surface of the terminal, and wherein the contact pad is electrically operatively coupled to the image sensor via the integrated circuit; the imager further comprising at least one stand-off projecting from at least one of the optical device and the imaging unit, the stand-off comprising a referencing element for mounting the optical element to the imaging unit.
