Zusammenfassung:	PROBLEM TO BE SOLVED: To enhance the sensitivity of a cumulation type chemical/physical phenomenon detector. SOLUTION: After the charge of a sensing part is moved to a floating diffusion part, the potential change of the floating diffusion is read using FET and JFET (junction field-effect transistor) of lower noise is used in this FET. Further, a combination structure of a floating diffusion region and the gate electrode of the JFET is formed to achieve miniaturization and the further lowering of noise. COPYRIGHT: (C)2008,JPO&INPIT
