Abstract
PURPOSE:To reduce false signals and blooming while avoiding an influence of a parasitic transistor by constituting p-n junction by a semiconductor substrate and the 1st impurity layer and by providing the 2nd impurity layer, connected to a DC power source, in the 1st impurity layer. CONSTITUTION:In impurity layer 505. impurity layer 504 is further provided and the junction between layers 505 and 504 is made by diode 608. When intense light arrives, the potential of point (a) is held at EC by current ic flowing from layer 504 to layer 505. Consequently, any base current of the parasitic transistor composed of layers 505 and 507 and silicon substrate 506 does not flow and no current flows from impurity layer 507 to impurity layer 505 undoubtedly, so that any false signal will be generated. Additionally, although layers 504 and 505 and the substrate form parasitic transistor Trn, the effect of parasitic Tr is removed without a change since the base potential is reversely biased and the current amplification factor of parasitic transistor Trn is held low.
