  • Patent number: 8580078
    Abstract: A bevel etcher incorporating a vacuum chuck used for cleaning the bevel edge and for reducing the bending curvature of a semiconductor substrate. The bevel etcher includes a vacuum chuck and a plasma generation unit which energizes process gas into a plasma state. The vacuum chuck includes a chuck body and a support ring. The top surface of the chuck body and inner periphery of the support ring form a vacuum region enclosed by the bottom surface of a substrate mounted on the support ring. A vacuum pump evacuates the vacuum region during operation. The vacuum chuck is operative to hold the substrate in place by the pressure difference between the top and bottom surfaces of the substrate. The pressure difference also generates a bending force to reduce the bending curvature of the substrate.

  • Patent number: 8578760
    Abstract: Container inspection utilizing a linear actuator. A linear actuator shaft is movable such that the shaft end temporarily contacts the container. A feedback parameter resulting from or related to a change of an electrical property of the linear actuator, is detected or determined by a controller, which determines whether the container satisfies pre-determined inspection criteria, e.g., whether the container is properly sealed, satisfies pressure criteria and/or has unacceptable vacuum. These determinations are made based at least in part upon one or more detected feedback parameters including or related to at least one of a change of position of the shaft, a change of velocity of the shaft and a force or torque exerted by the container to the shaft. In this manner, high speed leak detection is performed without a load cell or force transducer, without squeezing or compressing bottles and without determining fill level changes.

  • Patent number: 8580130
    Abstract: Laser-assisted apparatus and methods for performing nanoscale material processing, including nanodeposition of materials, can be controlled very precisely to yield both simple and complex structures with sizes less than 100 nm. Optical or thermal energy in the near field of a photon (laser) pulse is used to fabricate submicron and nanometer structures on a substrate. A wide variety of laser material processing techniques can be adapted for use including, subtractive (e.g., ablation, machining or chemical etching), additive (e.g., chemical vapor deposition, selective self-assembly), and modification (e.g., phase transformation, doping) processes. Additionally, the apparatus can be integrated into imaging instruments, such as SEM and TEM, to allow for real-time imaging of the material processing.

  • Patent number: 8582925
    Abstract: This invention provides a system and method for employing GUI-based non-numeric slide buttons and bar meters to setup and monitor operating parameters of a vision system. Graphical representations of operating parameters are displayed in a parameter box on the GUI with moving bars that are shaded, patterned or colored so as to provide a relative level between two extremes on a scale of the given operating parameter. Input of operating parameter settings with respect to the scale is made by moving a setting slider along the scale between the extremes. The position of the slider establishes the user-input setting relative to the scale. In an illustrative embodiment, scales, level bars and setting sliders can also be displayed on the image view itself, adjacent to a given image view feature, which is the subject of the scale.

  • Patent number: 8580969
    Abstract: The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides a more efficient route for preparing the enone intermediate.
