Title: Solid-state imaging element
Inventor: CHIYOMORI MOTOYUKI
IPC: H04N5/335
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To suppress knee component caused by voltage drop, by applying a ground electric potential on both ends corresponding to both ends in a vertical direction of imaging region, in a channel stop region, so that Hall current flows in two directions for suppressing a voltage drop to a half. SOLUTION: With contact to the upper and lower ends of a channel stop region 34, or both upper and lower ends of an imaging region, in other words, the upper and lower ends corresponding to both upper and lower ends of an effective pixel region 35, a ground electric potential is applied. With this configuration, the Hall current generated by photoelectric exchange flows toward both ends of the channel stop region 34 when it is discharged from a positive electric charge accumulation region through the channel stop region 34. Thus, a voltage drop in a p-type positive electric charge accumulation region of a photo-detecting element away from the terminal part of ground electric potential is suppressed, for a suppressed knee characteristics.
