    摘要： A charge-coupled device comprises transfer gate electrodes separated from a substrate by a multi-layer insulating film, and gate electrodes of MIS transistors separated from the substrate by a single layer insulating film. The multilayer insulating film comprising at least a lower silicon oxide layer of 10 nm to 200 nm thickness and an upper silicon nitride layer of 10 nm to 100 nm thickness. Since each of the gate insulating films of the MIS transistors is the same layer as the lower silicon oxide layer, there occurs no degradation in the transistor characteristics due to the surface states or the trapping states present within the silicon nitride layer.

The control unit is configured to execute a positional displacement correction control to calculate an amount of the positional displacement and determine respective target drive speeds of the plurality of drive sources. The control unit is also configured to control so that the positional displacement detection pattern is formed when the plurality of drive sources are driven at substantially identical speeds and the positional displacement detection pattern thus formed is sensed by the image sensor.
