Abstract: A process for filling high aspect ratio gaps on substrates uses conventional high density plasma deposition processes, with an efficient sputtering inert gas, such as Ar, replaced or reduced with an He inefficient sputtering inert gas such as He. By reducing the sputtering component, sidewall deposition from the sputtered material is reduced. Consequently, gaps with aspect ratios of 6.0:1 and higher can be filled without the formation of voids and without damaging circuit elements.

Abstract: A method of forming a BPSG film in a PECVD reactor with ratios of P.sub.2 O.sub.3 /P.sub.2 O.sub.5 such that the film flows at low temperature in a non-oxidizing ambient and produces a reduced number of particulates. The method permits tailoring of the wall angle of a BPSG film by controlling the P.sub.2 O.sub.3 /P.sub.2 O.sub.5 ratio.

Abstract: A nozzle for supplying lubricants to conveyors comprises a plastic housing for a spring loaded valve which can be adjusted to produce either a fan stream or a needle point stream with a minor adjustment of the valve. Contaminating material can be removed from the device by a purge tool which interfits with the valve, and the tool can easily be hand manipulated to lift the valve against the spring loading and effect purging.

Abstract: A pneumatically controlled system for cleaning conveyor belts is provided which applies cleaning compounds such as detergents and chemicals to the belts through nozzles positioned between the belts. Following application of the cleaning compounds, a rinse cycle is then applied to remove dirt and residue from the conveyor belts, and the process is repeated at suitable intervals. The belt cleaning process may be carried out during normal production operations or after production hours.

Abstract: An air actuated apparatus and method for lubricating conveyors such as chains and belts is disclosed, comprising a device including air actuated valves which are alternately opened and closed by a drive system powered from the conveyor movement. The drive system is connected to a delay valve which controls a fluid valve that enables lubricating solution to be applied to the conveyor. The apparatus and method are particularly suited for conveyors operating at high speed, and may also be used to control a plurality of lubricating applicators for different conveyors in a plant.

Abstract: A window achieves broad band infrared reflection with a thin reflective layer and a clear interference coating on its outside surface. Color viewed from outside is enhanced by varying the thickness of the interference coating, while the window still exhibits neutral color to transmitted light. The reflective layer is formed of a metal such as copper, gold or copper alloy to provide enhanced IR reflection extending beyond ten microns. The metal is preferably deposited without agglomeration, and with uniformity that permits high and neutral transmission of visible light.

Abstract: An apparatus and method for lubricating conveyors and belts used in the food industry is disclosed, comprising a device including valves which are alternately opened and closed by an actuating device driven from the conveyor movement. The valves supply a lubricant which is fed to output nozzles for spraying onto the conveyors for lubricating purposes, and the valves will only feed lubricant when the conveyor is moving. Consequently, lubricant and water wastage are significantly decreased, along with excess sewage charges, and the need for a conventional electrically driven solenoid system for controlling the output of lubricant is eliminated.

Abstract: A spray nozzle comprises a hollow body having an inlet, an outlet and a fluid flow passage therebetween. The body contains a pressure-responsive or a pressure responsive and temperature responsive valving element that increases the effective area of the outlet in response to an increase in pressure or an increase in pressure and/or temperature. In a preferred embodiment, the outlet includes a restricted orifice and an unrestricted orifice, and the valving element is movable within the body between a first position in which the restricted orifice is open and the unrestricted orifice is closed, and a second position in which the unrestricted orifice is open. The valving element is biased in the first position by a spring which applies a selectable biasing force that defines a threshold pressure, so that the valving element is moved to the second position by a dynamic pressure of the fluid flowing through the flow passage that is greater than the threshold pressure.

Abstract: Surface treatment of a substrate by ion beam sputtering (IBS). The sputtered material impacts on the substrate with a kinetic energy which may be several orders of magnitude higher than in conventional sputter deposition techniques, and material is deposited along a path with high energy directed substantially normal to the target surface, allowing precise control of deposition conditions.Novel treatment processes with IBS sputtering include coating or activating of circuit board holes, alloying or transformation of surface chemistry, and the deposition of metallic, crystalline or large-molecule coatings which are intimately bonded to a crystalline or amorphous substrate. Special homologous and graded coatings allow the repair of lattice damage in crystalline substrates, and permit the formation of stress free and crystalling layers, and other coatings with diverse electrical, optical, chemical or other physical surface properties.

Abstract: A semi-reflecting layer is deposited on a transparent material as part of a technique for color enhancement in such a way that the reflectivity of the semi-reflecting layer may still be varied in order to control transmission of light and portions of the electromagnetic spectrum thereto over a broad range of frequencies. For purposes of color enhancement there is used in conjunction with the semi-reflecting layer a thin dielectric layer the thickness whereof is selected to make use of optical interference between light reflected from the outer surface of the dielectric layer and light reflected from the semi-reflecting layer.

Abstract: A solution of water soluble conveyor lubricant is continuously recovered from a moving conveyor through a suction bar. The lubricant is treated to reduce suspended solids, heat sterilized, the pH adjusted, and a bactericide is added. The solution is then recycled at least once to obtain about a 50%-90% recovery, and then is discharged. The process saves a significant amount of water, in addition to lubricant.

Abstract: Brazing of elements to electronic chip carrying substrates requires brazing materials strong at high temperatures used to remove and replace chips. Flanges and pins are brazed with Au:Sn brazing alloys modified during brazing by addition of copper to the brazing material to promote formation of the higher melting point .beta. phase of the alloy and a Group VIII metal to draw Sn out of the melt by gettering, also to promote formation of the .beta. phase of the alloy and to thicken the braze material. A copper preform is plated with Ni and juxtaposed with surfaces to be brazed and the brazing material to add Ni and copper to the melt.

The apparatus is also configured to detect pattern changes and image object movement.

Abstract: Solar cells are manufactured by a simplified method in which a single protective layer acts as an anti-reflection coating and an encapsulation. In cases where the junction is formed by ion implantation techniques, the same layer also serves as the implantation oxide. In addition, this multi-purpose layer may also serve as a mass analyzer, allowing the desired species of ions to reach the surface of the semiconductor but blocking the heavier undesired species. The necessary contacts may be formed prior to implantation, and the use of alloyed aluminum contacts with aluminum oxide passivation permits a simplified contacting procedure. A fully automatic contacting method and configuration for linear materials is also disclosed.
