Abstract: A sensor chip includes a sensor pixel. The sensor pixel includes an avalanche photodetector. A circuit is adjacent to the avalanche photodetector. The circuit is coupled to the avalanche photodetector. An isolation structure at least partially encloses the circuit and is between the avalanche photodetector and the circuit.

Abstract: An integrated circuit includes a photodetector that has an epitaxial layer with a first conductivity type located over a substrate. A buried layer of the first conductivity type is located within the epitaxial layer and has a higher carrier concentration than the epitaxial layer. A semiconductor layer located over the buried layer has an opposite second conductivity type and includes a first sublayer over the buried semiconductor layer and a second sublayer between the first sublayer and the buried layer. The first sublayer has a larger lateral dimension than the second sublayer, and has a lower carrier concentration than the second sublayer.

Abstract: A pulsed light source illuminates a scene with a virtual array of points. Light reflected by the scene is detected by a small pixel array, allowing generation of a three-dimensional map of the scene. A processing element processing data output by the small pixel array uses a multipath resolution algorithm to resolve individual objects in the scene.
