Abstract:
1. A method for fabricating an image sensor, comprising: providing a substrate having a plurality of semiconductor devices formed thereon; forming a plurality of interlayer insulating films and a plurality of interlayer conductive films on the substrate alternately, wherein the interlayer conductive films are electrically connected to the semiconductor devices; forming a plurality of isolated photo-diodes on the topmost layer of the interlayer conductive films, wherein a bottom amorphous silicon layer of the isolated photo-diodes are electrically connected to the topmost layer of the interlayer conductive films; forming a top insulating layer on the topmost layer of the interlayer conductive films, wherein the isolated photo-diodes are covered by the top insulating layer; and forming a top conductive layer in the top insulating layer, wherein the top conductive layer is electrically connected to a top amorphous silicon layer of the isolated photo-diodes, and the step of forming the top insulating layer comprises:
