Abstract
An amplification type solid state imaging device in use includes at least a light-receiving portionformed by arranging on a semiconductor substrateone-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 circuitfor suppressing spurious signals for the electric signals read out by the reader, and a first light-shielding layerpositioned on the upper part of the light-receiving portionso as to restrict entry of light into parts other than photoelectric conversion portionsof the pixels. Furthermore, a second light-shielding layerfor restricting entry of light into the noise rejection circuitis provided on the upper part of the noise rejection circuit
