Abstract:
An amplification type solid state imaging device in use includes at least a light-receiving portion 10 formed by arranging on a semiconductor substrate 7 one-dimensionally or two-dimensionally a plurality of pixels that convert incident light to signal charge and output electric signals corresponding to the amount of the signal charge, a reader for reading out sequentially the electric signals from the respective pixels, a noise rejection circuit 11 for suppressing spurious signals for the electric signals read out by the reader, and a first light-shielding layer 1 positioned on the upper part of the light-receiving portion 10 so as to restrict entry of light into parts other than photoelectric conversion portions 10a of the pixels. Furthermore, a second light-shielding layer 2 for restricting entry of light into the noise rejection circuit 11 is provided on the upper part of the noise rejection circuit 11.
