Abstract
A photosensitive element has a two tier passivation layer disposed between the top contact layer and the amorphous silicon photosensor island. The passivation layer includes an inorganic moisture barrier layer which is disposed at least over the sidewalls of the photosensor island. The inorganic material forming this layer is preferably silicon nitride or silicon oxide. An organic dielectric layer is disposed over the moisture barrier layer and the photosensor island except for a selected contact area on the top surface of the photosensor island where the top contact layer is in electrical contact with the amorphous silicon material of the photosensor island. The organic dielectric material is preferably a polyimide.
