摘要： A photoelectric conversion apparatus includes a pixel including a photoelectric conversion unit for outputting a first signal in response to incidence of a photon, the photoelectric conversion unit including an avalanche diode for multiplying a charge occurring from the incidence of the photon by avalanche multiplication, a counter for counting a signal output from the photoelectric conversion unit, and a signal processing circuit connected between the counter and the photoelectric conversion unit and configured to control output of a third signal based on the first signal and a second signal. The signal processing circuit includes a first element having a first withstand voltage and a second element having a second withstand voltage and is configured such that the first signal is input to the first element and the second signal is input to the second element, the second withstand voltage being a withstand voltage lower than the first withstand voltage.

摘要： A photoelectric conversion apparatus includes a first substrate and a second substrate. A plurality of wiring layers of a second wiring structure includes a wiring layer where first wiring for supplying a power supply voltage to a plurality of pixel circuits is disposed and an area occupied by the first wiring is the largest among the plurality of wiring layers, and a wiring layer group where the first wiring is disposed, the wiring layer group being located between the wiring layer where the area and a second semiconductor layer. In a plan view, the first wiring is configured to connect both ends of a region in a first direction and both ends of the region in a second direction intersecting the first direction by combination of the wiring layer group, the region including each of the plurality of pixel circuits.
