Abstract
A photoelectric conversion apparatus includes a semiconductor substrate, a plurality of avalanche diodes formed within the semiconductor substrate, the plurality of avalanche diodes including a first avalanche diode and a second avalanche diode, and a trench structure formed between the first avalanche diode and the second avalanche diode in a plan view. Each of the avalanche diodes includes a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type. A contact plug for supplying a potential to the second semiconductor region of the first avalanche diode is formed, and the contact plug is provided at a position where the contact plug overlaps with the trench structure in a plan view.
