Abstract: A solid-state imaging device that prevents the transfer errors of the signal charges from vertical charge-transfer sections to a horizontal charge-transfer section. A first plurality of buried channel regions in vertical charge-transfer sections are connected to a second buried channel region in a horizontal charge-transfer section so that the interfaces between the first plurality of buried channel regions and the second buried channel region are located to be aligned with the corresponding ends of the first plurality of gate electrodes. Thus, no potential dip nor potential barrier are generated in the vicinity of the interfaces between the first plurality of buried channel regions and the second buried channel region.
