ABSTRACT:
Forming an impurity region6and an impurity region5having a lower concentration than the impurity region6in a lower layer region of a gate electrode close to the boundary with a signal electron-voltage conversion section of a horizontal CCD outlet makes it possible to smooth a potential distribution at the time of transfer, improve the transfer efficiency, increase the number of saturated electrons and reduce variations in the transfer efficiency and variations in saturation.
