Semiconductor device and signal processing device having said device provided therein

摘要

A semiconductor device is provided with plural charge accumulation type sensor elements, each of the sensor elements having an active semiconductor region. Plural charge transferring elements transfer charge signals which are stored in the sensor elements, each of the charge transferring elements corresponding to a respective one of the sensor elements. A common conductive member is provided with an insulating member to be capacitively coupled with the sensor elements. An operating member produces a drive signal to drive the charge transferring elements and detects the voltage signal on the common conductive member. The charge transferring elements are controlled on the basis of a voltage signal corresponding to the respective voltages accumulated in the sensor elements in accordance with a voltage of the common conductive member.
