Claim:
1. A solid-state imaging device comprising: a first semiconductor section including a first wiring layer at a first side thereof, the first semiconductor section including a photodiode at a second side opposite to the first side of the first semiconductor section, at least a transfer transistor, a reset transistor, and an amplification transistor; a second semiconductor section including a second wiring layer at a first side thereof and a plurality of transistors, the first and second semiconductor sections being secured together; a third semiconductor section including a third wiring layer at one side thereof, the second and the third semiconductor sections being secured together such that the first semiconductor section, second semiconductor section, and third semiconductor section are stacked together; and a first conductive material connecting with the first wiring layer in the first semiconductor section and a second conductive material in the second semiconductor section, wherein a portion of the second conductive material extends in a lateral direction in the second semiconductor section, wherein,
