Claim 14:
15. A semiconductor device comprising:
a plurality of single-photon avalanche diode pixels, wherein each of the single-photon avalanche diode pixels has a center;
a plurality of first microlenses, wherein at least one of the first microlenses covers each of the plurality of single-photon avalanche diode pixels; and
a plurality of second microlenses, wherein each second microlens fills a gap in a respective one of the plurality of first microlenses, each second microlens and the respective one of the plurality of first microlenses together overlap a respective single-photon avalanche diode pixel, and each of the first and second microlenses are configured to redirect light toward the center of the respective single-photon avalanche diode pixel.
