ABSTRACT:
A solid-state image pickup device of the charge-coupled type is improved in that the width W1 (as viewed in the charge transfer direction) of each of the transfer gate electrodes for generating transfer elements in the field shift mode, the width W2 (as viewed in the charge transfer direction) of each of the transfer gate electrode for generating potential barriers also in the field shift mode are selected so as to satisfy the following formula, and a buried channel junction depth X.sub.JBC of each of the vertical charge transfer paths are selected so as to satisfy W1>W2 and/or W2>2.multidot.X.sub.JBC. In the inventive image pickup device, the charge quantity transferred is increased without impairing the vertical resolution of the device.
