Abstract
A sensor includes a first substrate including at least a first pixel. The first pixel includes an avalanche photodiode to convert incident light into electric charge and includes an anode and a cathode. The cathode is in a well region of the first substrate. The first pixel includes an isolation region that isolates the well region from at least a second pixel that is adjacent to the first pixel. The first pixel includes a hole accumulation region between the isolation region and the well region. The hole accumulation region is electrically connected to the anode.
