Abstract
An image sensor includes a plurality of photodiodes arranged in an array and disposed in a semiconductor material to receive light through a first surface of the semiconductor material. At least part of the semiconductor material is curved. A carrier wafer is attached to a second surface, opposite the first surface, of the semiconductor material, and a polymer layer is attached to the carrier wafer, so that the carrier wafer is disposed between the polymer layer and the semiconductor material.
