Abstract: A photodiode is formed in a semiconductor substrate having a first surface and a second surface. The semiconductor substrate includes a first N-type semiconductor region formed by epitaxial growth and a second N-type semiconductor region (that is more heavily doped than the first region) extending into the first N-type semiconductor region from the first surface. The dopant concentration of the first N-type semiconductor region gradually increases between the second surface and the first surface of the semiconductor substrate. An implanted heavily P-type doped region is formed in the second N-type semiconductor region at the first surface.

Abstract: An electronic device is provided that includes a photodiode. The photodiode includes a semiconductor region coupled to a node of application of a first voltage, and at least one semiconductor wall. The at least one semiconductor wall extends along at least a height of the photodiode and partially surrounds the semiconductor region.

Abstract: A photodiode include a first substrate layer of a first dopant type and a second substrate layer of a second dopant type on top of the first substrate layer. Semiconductor walls are provided in a semiconductor substrate which includes the first and second substrate layers. The semiconductor walls include: two outer semiconductor walls and at least one inside semiconductor wall positioned between the two outer semiconductor walls. Each inside semiconductor wall is located between two semiconductor walls having longer length.

Abstract: A pixel includes a photoconversion zone, an insulated vertical electrode and at least one charge storage zone. The photoconversion zone belongs to a first part of a semiconductor substrate and each charge storage zone belongs to a second part of the substrate physically separated from the first part of the substrate by the insulated vertical electrode.
