Abstract
Provided is a solid-state imaging device that includes a first semiconductor layer including a first photoelectric conversion element that photoelectrically converts light to a signal charge, and a charge holding region that holds the signal charge, a second semiconductor layer on the first semiconductor layer with a first insulating layer interposed therebetween and includes a second photoelectric conversion element that photoelectrically converts light, a circuit substrate unit on the second semiconductor layer with a second insulating layer interposed therebetween and includes a readout circuit that reads out the signal charge, an element-side first metal pad on the second insulating layer, a circuit-side first metal pad on the circuit substrate unit and is connected to the readout circuit and bonded to the element-side metal pad, and a first contact electrode that penetrates the first and second insulating layers and electrically connects the charge holding region and the element-side first metal pad.
