  • Publication number: 20230115183
    Abstract: An image sensor device includes a pixel. The pixel includes a semiconductor layer having a first surface. A photodiode is formed in the semiconductor layer and is configured to generate charge carriers based on light reaching the photodiode. A storage node is formed in the semiconductor layer, the storage node being arranged so that charge carriers generated in the photodiode are transferred to the storage node. A light-shielding structure is formed in the semiconductor layer and is disposed at least between the first surface of the semiconductor layer and the storage node so as to prevent at least part of the light travelling in the semiconductor layer away from the first surface from reaching the storage node.

  • Patent number: 11594654
    Abstract: A method of generating a germanium structure includes performing an epitaxial depositing process on an assembly of a silicon substrate and an oxide layer, wherein one or more trenches in the oxide layer expose surface portions of the silicon substrate. The epitaxial depositing process includes depositing germanium onto the assembly during a first phase, performing an etch process during a second phase following the first phase in order to remove germanium from the oxide layer, and repeating the first and second phases. A germanium crystal is grown in the trench or trenches. An optical device includes a light-incidence surface formed by a raw textured surface of a germanium structure obtained by an epitaxial depositing process without processing the surface of the germanium structure after the epitaxial process.

  • Patent number: 10545225
    Abstract: An optical sensor device configured to detect a time of flight of an electromagnetic signal includes a semiconductor substrate with a conversion region configured to convert at least a portion of the electromagnetic signal into photo-generated charge carriers. A deep control electrode is formed in a trench extending into the semiconductor substrate. The deep control electrode extends deeper into the semiconductor substrate than a shallow control electrode.
