Abstract:
A photosensor includes a plurality of avalanche photodiodes (APD) provided on a first main surface, a first isolation region that is provided on the first main surface and electrically separates the plurality of APDs from one another in a first direction, and a second isolation region that is provided on the first main surface and electrically separates the plurality of APDs from one another in a second direction different from a direction of the first isolation region. The first isolation region and the second isolation region are depleted. At least one of the first isolation region or the second isolation region is terminated at a first connection portion at which the first isolation region and the second isolation region are connected.
