Patent ID: 8604576

Claim:
An image sensor package, comprising: an image sensor chip that 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 crystalline handler having opposing first and second surfaces, and a cavity formed into the first surface, wherein a compliant dielectric material is disposed in the cavity, and wherein the image sensor chip substrate front surface is attached to the crystalline substrate handler second surface; the crystalline handler includes a plurality of electrical interconnects each comprising: a hole aligned with one of the contact pads, with a first portion extending from the second surface to the cavity and a second portion extending through the compliant dielectric material, a layer of insulation material formed along a sidewall of the first portion of the hole, and conductive material extending through the first and second portions of the hole, wherein the conductive material is electrically coupled to the one contact pad.
