Charge transferring device having an FDA type charge detecting section and a method for producing the same

摘要

A charge transfer device includes: a transfer channel for transferring a charge in a charge transfer direction; a charge detecting section having a diffusion layer for storing the charge transferred through the transfer channel and for inducing a voltage corresponding to the amount of the stored charge; and a transistor for detecting the induced voltage, the transistor having: a gate electrode formed on the diffusion layer, the gate electrode being in direct contact with the diffusion layer; a gate insulating film formed on the gate electrode; and a channel region formed above the gate electrode.
