    Abstract: A PROCESS WHICH INCLUDES THE PREPARATION OF A SUBSTRATE AND SUBSEQUENT EPITAXIAL DEPOSITION OF GERMANIUM ON THE SUBSTRATE IS DESCRIBED. PREPARATION OF THE SUBSTRATE, EITHER GERMANIUM OR GALLIUM ARSENIDE, INCLUDES A CHEMICAL TREATMENT STEP TO REMOVE SURFACE FILMS, RAPID QUENCHING, RINSING AND DRYING STEPS, AND A HEATING STEP PRIOR TO DEPOSITION. DEPOSITION OF GERMANIUM IS CARRIED OUT IN AN OPEN TUBE DISPROPORTIONATION SYSTEM, BY INTRODUCING A GERMANIUM HALIDE SPECIE WHICH IS CAPABEL OF DISPROPORTIONATING AT A DEPOSITION SITE IN CONCENTRATIONS AND AT VELOCITIES SUCH THAT THE DEPOSITION OF GERMANIUM TENDS TO BE SURFACE LIMITED RATHER THAN MASS TRANSPORT LIMITED. THE DEPOSITION, PREFERABLY CARRIED OUT ON A (110) ORIENTED SUBSTRATE, IS EPITAXIAL, SMOOTH AND SHINY AND IS SUITABLE FOR SUBSEQUENT PROCESSING REQUIRING PHOTOGRAPHIC TECHNIQUES.

    Abstract: A process for the in situ fabrication of a glass from an admixed frit, for example, of two starting glasses on the required existing substrate structure therefore. The admixed frit comprises a low glass transition temperature glass and a higher glass transition temperature glass, which glasses are uniquely capable of forming a continuous vitreous phase over their entire compositional range. During thermal cycling, the low glass transition temperature glass flows out and solubilizes the higher glass transition temperature glass to thereby synthesize in situ a new glass. The temperature required to form the glass by the in situ process is less than that required where a glass of identical composition is first preequilibrated externally and then applied in frit form to the existing substrate structure and flowed out thereon. The in situ synthesized new glass softens and flows at a temperature higher than that of the low glass transistion temperature glass and lower than that of the higher glass transition temperature glass, and exhibits a glass transition temperature intermediate to the two starting glasses.

    Abstract: An improved glass panel gas discharge display structure wherein a photolithography step on a plate forming the glass panel is used before metallizing the plate through a mask so that when subsequent dissolution of the mask takes place, the plate is left with embedded metallization essentially coplanar with the surface. The effects of such an embedded electrode structure are that it minimizes attack of the metallization when flow on dielectrics are applied since the sidewalls of the electrodes are protected; it permits application of very thin dielectrics by flow-on, sputtering, plasma spraying, evaporation or other suitable techniques since problems of overcoating around edges are eliminated. It minimizes stresses in the composite structure overlying the substrate support and it minimizes adjacent line interactions when very thin coatings are applied. It also minimizes surface irregularities on panel plates.

    Abstract: A high performance integrated circuit chip package (10) includes a support (15) substrate (12) having conductors extending from one face to the opposite face thereof and a multilayer wiring substrate (16) on the opposite face of the support substrate for connecting chips mounted thereon to one another and to the conductors. A heat sink includes microchannels at one face thereof, with thermally conductive cushions connecting the one face of the heat sink (26) with the exposed back sides of the chips, to provide a high density chip package with high heat dissipation. The multilayer wiring substrate (16) may be formed by a self-aligned thin film wiring method, with a self-aligned lift off method being employed to form internal wiring planes. The support substrate and heat sink may be formed of blocks of material having thermal expansion matching silicon. The cushions are a low melting point solder, preferably pure indium, and are sufficiently thick to absorb thermal stresses, but sufficiently thin to efficiently conduct heat from the chips to the heat sink.

    Abstract: A process for the fabrication of a deformographic storage display tube (DSDT) target in which a wafer of silicon or other etchable material is used (1) as a temporary support during the generation of the active region of the target and (2) as a supporting structure for the completed target. The DSDT target structure comprises a reflection layer on a dielectric layer supported in turn on a silicon or other etchable material wafer, the wafer being etched off at its back side to expose the dielectric layer while providing an outer frame support structure made of the wafer around the edge, with the dielectric layer being etched to form pillars of the dielectric on the backside of the reflection layer, whereby the dielectric pillars enable a deformation action to occur in the region between the pillars. An inner frame support structure comprised of a similarly etched wafer, a dielectric layer and a secondary electron emission layer is fitted against the bottoms of the pillars and bonded to the outer frame support structure, thereby forming the completed target.

    Abstract: Silicon or germanium crystals are vapourpolished by a stream of hydrogen iodide mixed with hydrogen or helium or a mixture thereof in a polishing chamber 9 through which the gas passes. Hydrogen or hydrogen and helium is passed through a heated packed bed 4 of iodine crystals, and hydrogen iodide is produced from the resulting mixture with iodine vapour in a platinum wool catalyst chamber 8.
