Claim Text:
1. An image sensor configured to capture image light, comprising: a semiconductor substrate having opposing first and second sides, wherein the first side includes an array of photosensitive elements and associated control circuitry and wherein the second side includes an array of corresponding color filter elements, wherein the image light reaches the photosensitive elements by passing through the color filter elements on the second side; a light blocking layer formed adjacent to the array of color filter elements on the second side of the semiconductor substrate; bond pads on the first side of the semiconductor substrate; a permanent carrier mounted on the semiconductor substrate; at least one dielectric layer that is formed on the permanent carrier, wherein openings are formed through the at least one dielectric layer and the permanent carrier; and a patterned metallization layer that is formed on the at least one dielectric layer and that has portions in the openings and portions that form contacts with the bond pads; and solder balls that are laterally offset from the bond pads and that contact the bond pads through the patterned metallization layer.
