Claim:
1. An optical sensor device comprising: an optical sensor die having an optical sensing area on a first surface, the optical sensor die configured to generate an output signal associated with light detected by the optical sensor die, wherein the optical sensor device is configured to position a lowermost surface of the optical sensor die adjacent a substrate above an uppermost surface of the substrate; an application-specific integrated circuit (ASIC) die arranged over the first surface of the optical sensor die, the ASIC die comprising circuitry at or near a second surface of the ASIC die, the circuitry comprising an integrated circuit and configured to process the output signal from the optical sensor die, the integrated circuit configured to modify the output signal and to transmit the modified output signal to the substrate; and a hole formed through the ASIC die, wherein the hole is at least partially aligned with the optical sensing area, wherein the optical sensor die covers sensitive circuitry of the ASIC die to protect the sensitive circuitry.
