摘要： A method and apparatus for directing an ion beam toward a surface of a substrate is disclosed. Certain embodiments of the invention relate generally to ion beam sources adapted to direct ion beams toward a surface of a substrate at an oblique angle of incidence relative to the surface. Certain embodiments of the invention are adapted to direct two ion beam portions toward a substrate surface, the ion beam portions having substantially equal throw distances. Preferred embodiments of the invention may be useful in etching applications, where the angle of incidence and throw distance of two ion beam portions are well suited for etching the surface of a substrate.

摘要： A chamber valve (100) for use in processes requiring vacuum pressures has a compact design which minimizes the space needed for the valve in the travel direction. The chamber valve gate (116) is moveable between a first position in which the gate is offset from the portal (110), and a second position in which the gate is aligned with the portal. The gate will move into alignment with the portal while remaining within a plane parallel or nearly parallel to the portal.

摘要： An apparatus for coating a substrate is provided that includes a racetrack-shaped plasma source having two straight portions and at least one terminal turnaround portion connecting said straight portions. A tubular target formed of a target material that forms a component of the coating has an end. The target is in proximity to the plasma source for sputtering of the target material. The target is secured to a tubular backing cathode, with both being rotatable about a central axis. A set of magnets are arranged inside the cathode to move an erosion zone aligned with the terminal turnaround toward the end of the target as the target is utilized to deposit the coating on the substrate. Target utilization of up to 87 weight percent the initial target weight is achieved.

摘要： A process for modifying a surface of a substrate is provided that includes supplying electrons to an electrically isolated anode electrode of a closed drift ion source. The anode electrode has an anode electrode charge bias that is positive while other components of the closed drift ion source are electrically grounded or support an electrical float voltage. The electrons encounter a closed drift magnetic field that induces ion formation. Anode contamination is prevented by switching the electrode charge bias to negative in the presence of a gas, a plasma is generated proximal to the anode electrode to clean deposited contaminants from the anode electrode. The electrode charge bias is then returned to positive in the presence of a repeat electron source to induce repeat ion formation to again modify the surface of the substrate. An apparatus for modification of a surface of a substrate by this process is provided.

摘要： A process for producing plasma coated glass substrates free of back side coating (BSC) is provided. A low-E glass coated structure is also provided that uses a BSC as a protective coating that promotes transport and handling of low-E glass that is then subsequently delaminated. A thin film is deposited on the back side of the glass substrate before the top side of the glass is coated. Then, during the sputter down process, BSC occurs as normal and deposits over this back side film (BSF). In a subsequent process, outside the vacuum chamber, the glass back side is washed or otherwise delaminated. The BSF composition is selected to make the BSC easily removed in this wash process or other delamination process.

摘要： A process for powering an electrical load includes applying a rectified alternating current waveform across the load for a first time period with only a single power supply for at least two half cycles. At least one half cycle of an alternating current waveform of opposite polarity are then applied relative to the rectified alternating current waveform across the load for a second time period. Rectified alternating current waveform is then again applied across the load for at least two half cycles for a third time period to power the electrical load. The rectified alternating current waveform can be applied a direct current offset. A power supply is provided for provided power across the load according to this process.

摘要： Presented is a method and apparatus for incrementally varying the frictional forces along an articulable column having succesive joints formed of alternate ball and socket members. Friction is varied by varying the contact angle between said ball and socket members along the length of the column and by supplying a compressive force to said joints via a tensioned means throughout the column. The effect of varying the frictional forces along the column is to vary the stiffness of individual column joints creating a structural member which can be tailored to the load requirements of a specific application.
