MICROLENS STRUCTURES FOR SEMICONDUCTOR DEVICE WITH SINGLE-PHOTON AVALANCHE DIODE PIXELS
An imaging device may include a plurality of single-photon avalanche diode (SPAD) pixels. The SPAD pixels may be overlapped by microlenses to direct light incident on the pixels onto photosensitive regions of the pixels and a containment grid with openings that surround each of the microlenses. Duri...
