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 1):
A semiconductor device, comprising:\n a silicon substrate having a first side and an opposing second side, wherein a distance between the first side and the second side is no more than approximately 50 microns; a first Single Photon Avalanche Diode (SPAD) provided in the silicon substrate; a second SPAD provided in the silicon substrate and also positioned adjacent to the first SPAD; at least one trench that electrically isolates the first SPAD from the second SPAD by extending from the first side of the silicon substrate to the second side of the silicon substrate, wherein the at least one trench begins at the first side of the silicon substrate and extends through both an n-doped portion of the silicon substrate and a p-doped portion of the silicon substrate all the way through the silicon substrate; and at least one backside contact positioned in proximity to the second side of the silicon substrate, wherein the at least one backside contact receives an electrical signal that is responsive to either the first SPAD or second SPAD receiving a photon.
