Patent ID: 8791419

Claim:
A pixel, comprising: a scan line proximate to a first surface of a substrate; a bias line between the first surface of the substrate and a first terminal of a photoelectric conversion element, a switching element proximate to the first surface of the substrate and aligned with at least a portion of the scan line, comprising: a first terminal; a second terminal; and a gate electrode electrically coupled to the scan line, wherein the first terminal of the switching element and the second terminal of the switching element are electrically coupled based on a scan signal from the scan line; the photoelectric conversion element proximate to the first surface of the substrate, comprising: the first terminal of the photoelectric conversion element electrically coupled to the bias line; and a second terminal of the photoelectric conversion element electrically coupled to the first terminal of the switching element; and a signal storage element proximate to the first surface of the substrate, comprising: a first terminal of the signal storage element electrically coupled to the bias line; and a second terminal of the signal storage element electrically coupled to the first terminal of the switching element and aligned with at least a portion of the photoelectric conversion element; a dielectric layer in proximate to the first terminal of the signal storage element and the second terminal of the signal storage element, where the scan line, the bias line and the gate electrode of the switching element are in a first metal layer proximate to the first surface of the substrate.
