Abstract
A V-H transfer section is formed by the following steps: N+-type impurities are first ion-implanted in such a manner that they spread out into an area larger than a channel of a vertical transfer register. An electrode of the vertical transfer register and electrodes of a horizontal transfer register are then formed. Thereafter, P+-type impurities are implanted into the electrode of the vertical transfer register and the electrodes of the horizontal transfer register in a self-alignment manner.
