  • Patent number: 10544505
    Abstract: A method of performing deposition of diamond-like carbon on a workpiece in a chamber includes supporting the workpiece in the chamber facing an upper electrode suspended from a ceiling of the chamber, introducing a hydrocarbon gas into the chamber, and applying first RF power at a first frequency to the upper electrode that generates a plasma in the chamber and produces a deposition of diamond-like carbon on the workpiece. Applying the RF power generates an electron beam from the upper electrode toward the workpiece to enhance ionization of the hydrocarbon gas.

  • Publication number: 20190228970
    Abstract: Methods for forming a diamond like carbon layer with desired film density, mechanical strength and optical film properties are provided. In one embodiment, a method of forming a diamond like carbon layer includes generating an electron beam plasma above a surface of a substrate disposed in a processing chamber, and forming a diamond like carbon layer on the surface of the substrate. The diamond like carbon layer is formed by an electron beam plasma process, wherein the diamond like carbon layer serves as a hardmask layer in an etching process in semiconductor applications. The diamond like carbon layer may be formed by bombarding a carbon containing electrode disposed in a processing chamber to generate a secondary electron beam in a gas mixture containing carbon to a surface of a substrate disposed in the processing chamber, and forming a diamond like carbon layer on the surface of the substrate from elements of the gas mixture.

  • Publication number: 20180076049
    Abstract: A hard mask layer is deposited on a feature layer over a substrate. The hard mask layer comprises an organic mask layer. An opening in the organic mask layer is formed using a first gas comprising a halogen element at a first temperature greater than a room temperature to expose a portion of the feature layer. In one embodiment, a gas comprising a halogen element is supplied to a chamber. An organic mask layer on an insulating layer over a substrate is etched using the halogen element at a first temperature to form an opening to expose a portion of the insulating layer.

  • Patent number: 9524406
    Abstract: A workstation electro-optically reads targets by image capture, and includes a housing, a generally planar window, an imaging module, and a generally planar fold mirror between the window and the module. The module has an illuminating light assembly for directing illumination light along an illumination path through the window at a target for return therefrom during reading, and an image sensing assembly for detecting return illumination light through the window along an imaging path over an imaging field of view during reading. The fold mirror folds the illumination and the imaging paths. The fold mirror and the window lie in planes that are substantially parallel to each other to prevent reflections of the illumination light off of the fold mirror and the window from entering the imaging field of view as virtual images that degrade target detection by the image sensing assembly.

  • Patent number: 8998089
    Abstract: A method for controlling a workstation includes the following: (1) energizing a first illuminator to illuminate a first subfield of view with a first illumination pulse and subsequently energizing the first illuminator to illuminate the first subfield of view with a second illumination pulse; (2) exposing the array of photosensitive elements in the imaging sensor for a first sensor-exposure time and subsequently exposing the array of photosensitive elements in the imaging sensor for a second sensor-exposure time; and (3) processing an image captured by the imaging sensor to decode a barcode in the image. The first illumination pulse overlaps with the first sensor-exposure time for a first overlapped-pulse-duration, and the second illumination pulse overlaps with the second sensor-exposure time for a second overlapped-pulse-duration. The first overlapped-pulse-duration is different from the second overlapped-pulse-duration.
