摘要： A vertical transfer charge-coupled device for vertically transferring signal charges, a horizontal transfer charge-coupled device for receiving and horizontally transferring the transferred signal charges, an unwanted electron eliminator, and a potential barrier between the horizontal transfer charge-coupled device and the unwanted electron eliminator are provided on a semiconductor substrate. The potential barrier includes a first n-type diffusion layer, a second n-type diffusion layer that is in contact with one end thereof, and a third n-type diffusion layer that is in contact with the other end. The second n-type diffusion layer and the third n-type diffusion layer have higher impurity concentrations than the first n-type diffusion layer. As a result, a solid-state imaging device is provided with which the ability of the unwanted electron eliminator to eliminate unwanted electrons is enhanced, without decreasing the size of the charge handled by the horizontal transfer charge-coupled device, allowing image output even with a large optical volume signal.

摘要： A solid-state image pick-up device having a structure in which the amount of transferred charges is not reduced in a vertical CCD portion even if a pixel portion is made finer, and a method for manufacturing the solid-state image pick-up device are provided. A first p-type well and a second p-type well are formed on an N (100) silicon substrate. A vertical CCD n.sup.+ layer is formed in the second p-type well 3. Then, impurity ions are implanted into a surface layer of the N (100) silicon substrate including an upper layer portion of the vertical CCD n.sup.+ layer to form a p.sup.- layer. An isolating portion for isolating photodiode portions from the vertical CCD n.sup.+ layer and a read control portion for controlling the read of charges from the photodiode n layer are simultaneously formed on a portion adjacent to the vertical CCD n.sup.+ layer.

摘要： A gate electrode region of a junction transistor in a signal charge-voltage converter is allowed to have a structure that a gentle potential gradient is formed without generation of a potential barrier. Thus, it is possible to readily realize a signal charge-voltage converter which is high in S/N ratio without generation of reset noise and is excellent in signal charge-voltage conversion efficiency.
