Abstract
An imaging device includes a first semiconductor layer having a first surface and a second surface and a first photodetector having a first implanted region formed in the first semiconductor layer and a pad formed over the first implanted region. The imaging device also includes a readout circuit disposed over the first surface of the first semiconductor layer. The readout circuit has a plurality of contact plugs facing the first surface of the first semiconductor layer. The imaging device further includes a second semiconductor layer disposed below the second surface of the first semiconductor, a second photodetector having a second implanted region formed in the second semiconductor layer, and a metalized via extending through the first semiconductor layer and the second semiconductor layer and electrically connecting the second implanted region to a second of the contact plugs of the readout circuit.
