Abstract
PURPOSE:To improve the reliability by forming more than one layer of dark current suppression film between a transparent electrode and a photoconductive layer thereby suppressing the dark current even when strong field is applied on the joint interface. CONSTITUTION:Selenium compound such as As2Se3, CdSe, ZnSe is employed as a photoconductive material, then a transparent electrode 2 such as In2O3, SnO2 is provided on a transparent glass substrate 1 thereafter while heating the substrate to 1,000 deg.C a dark current suppression film 3 composed of more than one layer of Sb2O3, Bi2O3 is formed through spattering. Thereafter a photoconductive film As2Se3 4 is deposited and SnO2 electrode 5 is formed on the uppermost section. Consequently the dark current is suppressed thereby it can withstand against long term usage resulting in the improvement of the reliability.
