Abstract
A back irradiation type light-receiving device, on which light is incident from the back side with respect to a charge-reading section of a semiconductor thin plate, is provided with a reinforcement member on the charge-reading section side. Electric signals are fed in and out from the charge-reading section by way of a polysilicon lead having a short wiring length and a low-resistance aluminum lead which is formed, after the completion of all the steps requiring a high-temperature treatment, so as to be physically and electrically direct-connected to the polysilicon lead. Accordingly, a charge generated in response to the received light can be read out with a high efficiency, while enabling a high-speed operation.
