Abstract

PURPOSE:To prevent blooming and obtain a light shielding effect with high reliability, by forming an untransparent layer electrode through a dielectric film on both the upper part of the overflow control gate part, and the upper part of the part outside the photosensitive part. CONSTITUTION:The photosensitive part is formed on the p type Si substrate as n type diffusion layer 17. The overflow control gate 18 between the n type layer 17 and the n<+> layer 3 consists of n<-> layer, and it becomes a potential barrier. A light beam is made incident from the opening part 13 of the Al electrode 12, and the signal charge which has been generated by said incidence is stored in the potential well formed by the n layer 17 of the photosensitive part. The signal charge which has been stored is read out through the transfer control gate part 16. In case when an excessive signal charge has been generated by an intense incident light beam, suitable voltage is applied in advance to the Al electrode 12, so that said signal charge is discharged to the overflow drain part 3.
