Patent ID: 8432011

Claim:
An image sensor package, comprising: a handler assembly that includes: a crystalline handler having opposing first and second surfaces, wherein the crystalline handler includes a cavity formed into the first surface such that the cavity has a stepped sidewall that defines at least one step surface extending inwardly inside the cavity, and a plurality of conductive elements each extending from the at least one step surface, through the crystalline handler, to the second surface; a sensor chip disposed in the cavity, wherein the sensor chip includes: a substrate with front and back opposing surfaces, a plurality of photo detectors formed at the front surface, and a plurality of contact pads formed at the front surface which are electrically coupled to the photo detectors; a plurality of wires each extending between and electrically connecting one of the contact pads and one of the conductive elements; and a substrate disposed over the cavity and mounted to the crystalline handler, wherein the substrate is optically transparent to at least one range of light wavelengths.
