Abstract: A method used by an computerized export control system (105) for online information such as documents allows log-on (210) by a user only when the user has a verified citizenship that is recorded and available to the computerized export control system. The computerized export control system records (330) a user entered export control classification number (ECCN) for the new document, when the ECCN matches an ECCN on a recorded list of valid ECCN's. A document is recorded as being commerce restricted when at least one of the following statements is true (705, 710): no export classification control number (ECCN) is recorded for the document, and at least one recorded ECCN is export controlled. The system automatically notifies an Export Control Specialist (365) when a document is submitted that has an export workflow restriction.

Abstract: A method for electroplating a metallic layer onto the surface of a photovoltaic device absent any external electrical contacts to the surface. The photovoltaic device is placed in an electrolytic plating bath where it is illuminated with electromagnetic radiation to which the device is photovoltaically responsive. Plating from the electrolytic bath results from current flow generated in the device itself.

Abstract: A semiconductor cell for generating current in response to incident radiation, particularly solar energy, wherein a layer of material having charges is disposed over the PN current generating junction. The layer having charges possesses a net bound charge of the same polarity as the minority carriers associated with the underlying semiconductor material for aiding minority carrier flow across the PN junction and for minimizing recombination of those minority carriers at the surface of the semiconductor body.

Abstract: There is disclosed a monolithic light display comprising a matrix of light emitting diodes in an integral structure which is scannable to produce an alpha numeric character display. Each of the light emitting diodes is electrically isolated from each other diode in a supporting carrier, with the cathodes of the diodes connected in a series of groups by address lines and anodes connected in an orthagonal plurality of groups by bit lines or column lines. A strobing format logic address system is provided for lighting the individual diodes to emission for producing an alpha numeric character.There is also disclosed a method of making the foregoing which comprises moat etching a semiconductor substrate of a first conductivity to form a plurality of mesas in an orthagonal pattern desired for the ultimate alpha numeric display. A region of the opposite conductivity is then produced on the moat etched surface of the substrate by diffusing a suitable dopant therein.

Abstract: There is disclosed a method of manufacturing the foregoing which comprises placing an epitaxial layer of a first conductivity type semiconductor material upon a substrate of semiconductor material having an intrinsic or semi insulating conductivity. Then channels are etched through the epitaxial layer to the semi insulating semiconductor substrate, thereby forming the epitaxial material into a plurality of parallel ribs or ridges. After coating the entire surface of the channels and the ridges with a dielectric layer, a conductive material is deposited over the substrate to fill the channels with the conductive material which may be either a metal or polycrystalline silicon doped to have sufficient conductivity.
