Contact type image sensor

摘要

A contact type image sensor has a transparent dielectric substrate, an upper transparent electrode, a lower electrode provided on the transparent dielectric substrate, a semiconductor thin film sandwiched between the upper transparent electrode and the lower electrode and constituting a photoelectric conversion part, a transparent dielectric layer formed on a plane of the lower electrode, and an upper electrode formed on the transparent dielectric layer and connected to the upper transparent electrode. The transparent dielectric layer constitutes a capacitance of the image sensor between the upper and lower electrodes.
