  • Patent number: 12342641
    Abstract: The present disclosure relates to a pixel comprising: a photodiode comprising a portion of a substrate of a semiconductor material, extending vertically from a first face of the substrate to a second face of the substrate configured to receive light; a layer of a first material covering each of the lateral surfaces of the portion; a layer of a second material covering the portion on the side of the first face, first and second material having refractive indexes lower than that of the semiconductor material; and a diffractive structure disposed on a face of the photodiode on the side of the second face.

  • Patent number: 12324251
    Abstract: A single photon avalanche diode (SPAD) includes a PN junction in a semiconductor well doped with a first type of dopant. The PN junction is formed between a first region doped with the first type of dopant and a second region doped with a second type of dopant opposite to the first type of dopant. The first doped region is shaped so as to incorporate local variations in concentration of dopants that are configured, in response to a voltage between the second doped region and the semiconductor well that is greater than or equal to a level of a breakdown voltage of the PN junction, to generate a monotonic variation in the electrostatic potential between the first doped region and the semiconductor well.

  • Publication number: 20240014341
    Abstract: A device includes a single photon avalanche diode in a portion of a substrate, wherein the portion has an octagonal profile. The octagonal profile is delimited by a wall forming an octagonal contour around the portion. The device further includes an array of diodes, wherein each diode is located in a corner between four adjacent single photon avalanche diodes. Each single photon avalanche diode further includes a doped anode region. A shallow trench isolation is formed in each doped anode region. A polysilicon line forming a resistor is supported at the upper surface of the shallow trench isolation.
