Abstract

Disclosed is a image sensor (e.g., a CMOS image sensor) including pixels each having a transfer transistor and a drive transistor, in which the gate of at least one of the transistors has a boosting gate disposed over it comprised of a conductive film pattern with interposing an insulation film. Thus, a voltage applied to the boosting gate is capacitively coupled to at least one of the transfer gate of the transfer transistor and a drive gate of the drive transistor. The transfer gate is supplied with the sum of the transfer voltage and the boosting gate-coupling voltage as a result and there is no need for providing a high voltage generator for the image sensor. The dynamic range of operation may be enhanced if such a coupling voltage is applied to the drive gate of the drive transistor.
