Abstract:
1. A solid-state imaging device comprising: an imaging element that includes a first semiconductor substrate, a first wiring layer that is formed on a surface of the first semiconductor substrate, and a first metal layer that is formed on an upper portion of the first wiring layer, in which a pixel region which is a light sensing surface is formed on a rear surface side of the first semiconductor substrate; and a logic element that includes a second semiconductor substrate, a second wiring layer that is formed on a surface of the second semiconductor substrate, and a second metal layer that is formed on an upper portion of the second wiring layer, a signal processing circuit that processes a pixel signal obtained at the pixel region is formed in the logic element, and the logic element is laminated to the imaging element so that the first metal layer and the second metal layer are bonded to each other, wherein, the first metal layer and the second metal layer are connected to ground potential.
