  • Patent number: 10273570
    Abstract: 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.

  • Publication number: 20180044114
    Abstract: Embodiments of a pusher device may include a frame, guide rails coupled to the frame, a carriage slideable along the guide rails, and a linear positioner coupled to the carriage and frame and operable to move the carriage along the guide rails. Two or more lugs may be mounted to the carriage and rotatable between a resting position, in which the forward ends of the lugs can contact the transverse supports of a tram above the carriage, and a lowered position in which the lugs can pass below the transverse supports. In the resting position, the longitudinal axis of each lug may be inclined from rear to front, such that the lugs contact the tram with the front end (as opposed to a longitudinal side) of the lugs. The lugs be generally triangular, trapezoidal, or concave polygonal in profile. Corresponding methods and systems are also disclosed herein.

  • Publication number: 20170345628
    Abstract: A rotary sputter magnetron assembly for use in sputtering target material onto a substrate is provided. The assembly comprises a longitudinally extending target tube having a longitudinal central axis, said target tube extending about a magnet array that is configured to generate a plasma confining magnetic field adjacent the target tube, said target tube supported for rotation about its longitudinal central axis and a pair of side shunts positioned parallel to the longitudinal central axis, and on opposing lengthwise sides of said target tube.

  • Publication number: 20150299470
    Abstract: A scratch-resistant anti-reflective film in accordance with a particular embodiment includes an anti-reflective stack and a protective layer overlying the anti-reflective stack. The anti-reflective stack has at least six stack layers of alternating higher and lower refractive indexes. The protective layer is at least primarily composed of diamond-like carbon and has a thickness of not more than 5 nm. At least a 15 cm2 region of the film is continuous and has an average nanoindentation hardness of at least 8 GPa using the Continuous Stiffness Measurement Technique. An average reflectance off the film at the region from normal incident light of wavelengths from 425 nm to 675 nm is not more than 1%. Average a* and b* in CIELAB color space for reflectance off the film at the region from ?45° to 45° incident visible light are within a range from ?2.0 to 2.0.

  • Publication number: 20130220797
    Abstract: A method for operating a moving magnet magnetron is provided enhanced target utilization. A magnet pack is moved in a first 2-D motion profile with a variable velocity. The magnet pack is then translated in a second 2-D motion profile that varies relative to the first profile. This process moving and translating is repeated to provide enhanced target utilization. These varied movement and translation profiles preclude the formation of a diamond-shaped erosion area common to the prior art. Representative to such profiles are intersecting sigmoidal curves. The resultant target is characterized by a metal from that has better target utilization as the wear pattern precludes the diamond shaped erosion area common to the prior art and instead has a multiple erosion peaks.

  • Publication number: 20120231246
    Abstract: 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.

  • Publication number: 20070250267
    Abstract: A system and method is provided for establishing a substantially delta-V-free three-dimensional atomic satellite cloud cluster. In one embodiment, a satellite cloud cluster system comprises a plurality of satellites maintaining a three-dimensional periodic motion relative to a reference point. The plurality of satellites and the reference point maintain an orbital pattern around a celestial body. The three-dimensional periodic motion is symmetrical about at least two planes that intersect at the reference point.

  • Patent number: 6675050
    Abstract: A method, simulation, and apparatus are provided that are highly suitable for treatment of benign prostatic hyperplasia (BPH). A catheter is disclosed that includes a small diameter disk loaded monopole antenna surrounded by fusion material having a high heat of fusion and a melting point preferably at or near body temperature. Microwaves from the antenna heat prostatic tissue to promote necrosing of the prostatic tissue that relieves the pressure of the prostatic tissue against the urethra as the body reabsorbs the necrosed or dead tissue. The fusion material keeps the urethra cool by means of the heat of fusion of the fusion material. This prevents damage to the urethra while the prostatic tissue is necrosed. A computer simulation is provided that can be used to predict the resulting temperature profile produced in the prostatic tissue.
