摘要： PURPOSE:To reduce the generation of blooming by installing a capacitive device where one electrode is connected to a semiconductor region in a photoelectric converter of a vertical switch MOS for a solid-state image sensor and the other electrode is connected to a gate electrode of this vertical switch MOS. CONSTITUTION:A capacitive device PC is installed in such a way that one electrode is connected to semiconductor regions N of a photoelectric converter for a solid-state image sensor and that the other electrode is connected to a gate electrode of a vertical switch MOS. When the photoelectric converter is irradiated with the light, the information is stored therein. Then, if a reset signal line RP is selected during a horizontal retrace period, it is made possible to prevent one part of surplus photoelectrons from leaking to output signal lines HS when the strong light enters. If vertical scanning lines VL are selected in order to read out the information, an increase in a potential of the vertical scanning lines VL increases the potential of the photoelectric converter due to a coupling action of the capacitive device PC; accordingly, it is made possible to keep the photoelectric converter in a momentary unsaturated state; the surplus photoelectrons do not leak to the output signal lines HS; thereby it is made possible to reduce the blooming.

摘要： PURPOSE:To enhance a dynamic range and to improve an SN ratio by a method wherein a device is constituted by a switch MOS, a first photoelectric converter and a second photoelectric converter and the first photoelectric converter or the second photoelectric converter is constituted by a P-N junction whose impurity concentration is high as compared with the second photoelectric converter or the first photoelectric converter. CONSTITUTION:Semiconductor regions N constituting a photoelectric converter PD1 are formed at an impurity concentration of, e.g., about 10 [atoms/cm ]; semiconductor regions P PD of a photoelectric converter PD2 are formed at a high impurity concentration, e.g., at an impurity concentration of about 10 atoms/cm . That is to say, if the photoelectric converter PD2 constituted by a P-N junction whose impurity concentration is high as compared with that of the photoelectric converter PD1, it is possible to obtain a high saturation point pd2 in the PD2 as compared with a saturation point pd1 of the photoelectric converter PD1. When the information is read out, an added-up signal current Ipd of the photoelectric converters PD1 and PD2 is read out. That is to say, if a standard light quantity is set near a knee point K, it is made possible to improve an SN ratio by increasing the standard light quantity and to enhance a dynamic range.
