Abstract
A charge-coupled device has a multi-layer structure insulating layer is formed beneath a transfer electrode, floating electrodes and an electrode adjacent the floating electrodes so that pin hole phenomenon in a charge transfer section of the charge coupled device can be successfully prevented. On the other hand, a sole-layer structure insulating layer is formed beneath a gate electrode of a peripheral component so that a threshold voltage of the gate electrode of the peripheral component can be successfully controlled at a desired value.
