Abstract
Compatibility of high sensitivity with low remaining images, and low crosstalk can be achieved by a laminated solid-state image pickup device, which includes accumulating portions for accumulating electric signals, reading units for reading the electric signals, connecting members formed in contact with the accumulating portions, and a photoconductive film, and by a method for manufacturing the device. The photoconductive film is made of a non-crystalline semiconductor, and is configured by laminating a carrier multiplication layer, a light absorbing layer, a charge injection inhibiting layer of a second conduction type. Each of the connecting members is made of a semiconductor layer of a first conduction type, intrinsic or having a low impurity density, surrounded by a semiconductor layer of the second conduction type or a conductive material.
