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.

Claim (Index 19):
An array of Single Photon Avalanche Diode (SPAD) cubes, comprising:\n a silicon substrate; an array of photosensitive areas distributed across a first side of the silicon substrate, wherein each photosensitive area in the array of photosensitive areas is capable of producing an electrical signal in response to receiving light; a plurality of contacts distributed across a second side of the silicon substrate, wherein at least some of the plurality of contacts are configured to receive electrical signals from some of the photosensitive areas and not others of the photosensitive areas; at least one trench that extends from the first side of the silicon substrate all the way to the second side of the silicon substrate, that provides optical isolation between adjacent photosensitive areas in the array of photosensitive, and that provides electrical isolation between adjacent contacts in the plurality of contacts; and a dielectric layer substantially adjacent to the second side of the silicon substrate, wherein the at least one trench extends to and contacts the dielectric layer.
