摘要： The image pickup device of the invention has a path deeper in a semiconductor substrate, than a region wherein a channel is formed, upon turning on a first MOS transistor, under a gate thereof. The path is arranged by forming a P-type layer for forming a potential barrier, within a P-type well excluding a region below the gate of the first MOS transistor. Thus, even when the first transfer MOS transistor is securely turned off at accumulation, carriers overflowing from a photodiode can flow into the path, thereby enabling to accumulate the carriers, overflowing from the photodiode, in a carrier accumulation region. Such structure allows to suppress a dark current generation from an interface of a gate oxide film of the first transfer MOS transistor, and also to expand the dynamic range of the image pickup device by the carriers overflowing from the photodiode and flowing through the path into the carrier accumulation region.
摘要翻译：本发明的图像拾取装置在其栅极接通第一MOS晶体管时，具有比形成沟道的区域更深的半导体衬底。通过在除了第一MOS晶体管的栅极以下的区域的P型阱内形成用于形成势垒的P型层来设置路径。因此，即使当第一转移MOS晶体管在累积时被可靠地截止时，从光电二极管溢出的载流子也可流入路径，从而能够在载流子积聚区域中累积从光电二极管溢出的载流子。这种结构允许抑制来自第一传输MOS晶体管的栅极氧化膜的界面的暗电流产生，并且还通过从光电二极管溢出的载流子扩展图像拾取器件的动态范围，并流过该通道载体积聚区。
