Abstract
An image sensor includes a plurality of photodiodes disposed in a semiconductor material, and a through-semiconductor-via coupled to a negative voltage source. Deep trench isolation structures are disposed between individual photodiodes in the plurality of photodiodes to electrically and optically isolate the individual photodiodes. The deep trench isolation structures include a conductive material coupled to the through-semiconductor-via, and a dielectric material disposed on sidewalls of the deep trench isolation structures between the semiconductor material and the conductive material.
