ABSTRACT:
A solid state image sensor has vertical BCCD, semiconductor substrate and photoelectric transducer formed in thickness direction of the semiconductor substrate by comprising SIT (static induction transistor), wherein holes generated by incident light are stored in the photoelectric transducing part, and electrons of a number as many as m-times of the number of the stored holes are read out from the semiconductor substrate to the vertical BCCD, and thus sensitivity multiplication is obtained.
