Abstract: Disclosed is an electrographic imaging member consisting essentially of a supporting substrate, a hydrogenated amorphous silicon photogenerating layer, and in contact therewith a charge transporting layer of plasma deposited silicon oxide containing at least 50 atomic percent of oxygen.

Abstract: A dry process for the manufacture of microelectronic devices from a work piece, which may be carried out entirely in a vacuum chamber, and which involves the coating of the work piece with a thin film of a monomer, selectively polymerizing the monomer according to a pattern of the microelectronic device desired, heating the layer of monomer to evaporate unpolymerized monomer to expose electronic circuit materials thereunder, removing the exposed electronic circuit materials, and stripping the polymerized monomer resist from the surface of the work piece.

Abstract: A method of making an imaging system wherein an imaging member comprising a layer of softenable substantially electrically insulating material containing a dispersion of randomly oriented electrically photosensitive orientation particles is imaged by: (A) applying a uniform electric field across said member, (B) imagewise exposing said member to activating electromagnetic radiation, and (C) developing said member by decreasing the resistance of said softenable layer to reorientation of said orientation particles sufficiently to allow imagewise reorientation of said orientation particles, comprising providing an electrically insulating material, adding photosensitive electret particles and forming a layer while applying vibration.

Abstract: An electrical information or latent image storage system using a storage element which comprises a layer of substantially electrically insulating material having a layer of electrically photosensitive particulate material embedded therein, with a layer of semiconductor material overcoating one surface of the layer of insulating material, and an electrode on the opposite surface of the layer of insulating material. Information in the form of localized electrical charges of an electrical latent image is placed on the element by electrical or photo-electrical means, the information can be retrieved by scanning the element using an electrode-pair grid pattern, an electron beam, or other suitable means, and the retrieved information may be used, for example, through a computer, or reconstructed into a visible image corresponding to a latent image.
