Abstract
A single photon avalanche diode may include a first diode, a second diode and a third diode. The first diode includes a first PN junction vertically spaced from a light-receiving surface by a first depth. The second diode is in partial contact with the first diode. The second diode includes a second PN junction vertically spaced from the light-receiving surface by a second depth greater than the first depth. The third diode is in partial contact with the second diode. The third diode includes a third PN junction spaced from the light-receiving surface by a third depth greater than the second depth. The first to third diodes have different breakdown voltages from one another.
