| Zusammenfassung: | A light detection device includes a semiconductor substrate. The semiconductor substrate forms an APD and a temperature compensation diode so as to be spaced apart from each other when viewed from a direction perpendicular to a main surface. The semiconductor substrate includes a peripheral carrier absorbing portion surrounding the APD when viewed from the direction perpendicular to the first main surface and configured to absorb carriers located at the periphery. A part of the peripheral carrier absorbing portion is located between the APD and the temperature compensation diode when viewed from the direction perpendicular to the main surface. |
