Abstract
A semiconductor device, sensor, and array of SPAD cubes are described. One example of the disclosed sensor includes at least one Single Photon Avalanche Diode (SPAD) cube established in a substrate, the at least one SPAD cube including a photosensitive area that is configured to produce an electrical signal in response to light impacting the photosensitive area, where the photosensitive area is positioned at a first side of the at least one SPAD cube, a contact that receives the electrical signal, where the contact is positioned at a second side of the at least one SPAD cube that opposes the first side of the at least one SPAD cube, and at least one trench that spans an entire thickness of the substrate thereby electrically and optically isolating the at least one SPAD cube from adjacent SPAD cubes.
