<p>PURPOSE:To improve the residual leading image, by making the dark current of the photo conductive target into a suitable value through the partial contact of two or more insulating materials separately with the photo conductive layer. CONSTITUTION:The transparent conductive film 2 and CdSe 3 are laminated on the glass plate 1. Next, Sb2S3 is evaporated about 75Angstrom through the mesh mask having suitable opening rate. After that, the mask is removed and As2Se3 7 is evaporated by 1.5 to 2mum, forming the photo conductive targent 8. Thus, since Sb2S3 layer is present in island shape, the residual image at leading can remarkably improved and the leading and the dark current can be controlled with the opening rate of mesh. Further, other than CdSe, the superposition of layers of CdS solid solution or mixture can be effective.</p> |
