Inventor: TANABE AKITO
IPC: H04N5/3722
Filed: 2000-04-26
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a low voltage and low power consumption cannot be achieved since a substrate voltage is increased when the impurity concentration profile of a P-type region is changed to increase the inclination of knee characteristics while the substrate voltage and the inclination of the knee characteristics of a photoelectric conversion element in vertical-type overflow drain structure are expressed by the function of an impurity concentration profile such as the impurity concentration and thickness of the P-type region for forming a VOD barrier. SOLUTION: Directly below the center part of an N-type region 103 of a photoelectric conversion element 201, the impurity concentration of a P-type region 122 that is buried into an N-type silicon substrate 101 for forming is set higher than that of a P-type region 102 around the P-type region 122, or the thickness of the P-type region 122 is set thicker than that of the P-type region 102. Influence to the VOD barrier in the P-type region 122 by a P+ channel stopper 105 and the P-type region 107 is reduced, the inclination of knee characteristics is increased, at the same time the substrate voltage is decreased, the power consumption in a solid-state image pickup element such as a CCD image pickup is reduced, at the same time, the dynamic range of the quantity of light is expanded, and gradation can be fined.
