Abstract
According to one embodiment, a light detector includes a first semiconductor layer of a first conductivity type, a first region, a quenching part, a second region, and a first layer. The first region is located on a portion of the first semiconductor layer, includes a first-conductivity-type first semiconductor region that has a higher first-conductivity-type impurity concentration than the first semiconductor layer, and includes a second semiconductor region of a second conductivity type provided on the first semiconductor region. The quenching part is electrically connected to the second semiconductor region. The second region is located on another portion of the first semiconductor layer, includes a second-conductivity-type third semiconductor region, and includes a first-conductivity-type fourth semiconductor region provided on a portion of the third semiconductor region. The first layer is located on the second region and includes a resin that absorbs or reflects light.
