  • Patent number: 9236219
    Abstract: Measurements of line roughness are separated into groups depending upon pre-layers. Image data collected from similar pre-layer types are considered together in order to separate effects of line roughness from distortion of measurements caused by the pre-layers. The resulting line roughness measurements are used to estimate an aspect of line quality.

  • Patent number: 9098503
    Abstract: An image review system presents an image to a reviewer and records reviewer feedback, including reviewer position indicators relating to portions of the image and reviewer commentary data, which can be audio, visual, textual, etc. The reviewer position indicators and reviewer commentary data each have a time component, corresponding to when the reviewer indicated a position on the image and when the reviewer provided the commentary, respectively. During playback, the viewer can select a subset of the image of interest and get a playback of the reviewer commentary data that corresponds to the times represented by the reviewer position indicators that fall within the selected subset of the image. The reviewer position indicators can be collectively indicated by a heat map that, when laid over the image, indicates which portions of the image are commented on and how much time is spent there.

  • Patent number: 8828245
    Abstract: A fabricating method of a flexible circuit board includes the following steps. The metal carrier foil with metal oxide layer on its surfaces is provided first. The metal oxide layer is formed from the spontaneous oxidization of the metal carrier foil in ambient air and provides passive protection in a sulfuric acid solution or an acidic copper sulphate solution. A conductive seed layer is electroplated onto the metal oxide layer. A flexible insulating layer is formed onto the conductive seed layer by performing a polyimide casting process. The metal carrier foil is then peeled off from the conductive seed layer, which is supported by the insulating layer. A patterned circuit is formed on the insulating layer by performing photoresist coating, developing and etching.

  • Publication number: 20120094494
    Abstract: A method to further adjust the final CD of a material to be etched during an etching process, and after a photolithographic patterning process can include patterning a semiconductor substrate using a mask layer. The mask layer can comprise a hardmask material having a protruding feature with an initial width. A first plasma comprising carbon and fluorine can be introduced into a chamber, where residual carbon and fluorine is deposited on at least the chamber wall. A portion of the mask layer can then be removed with a second plasma incorporating the residual carbon and fluorine, whereby remaining hardmask material forms a feature pattern where the protruding feature has a final width different from the initial width. The feature pattern can then be transferred to the semiconductor substrate using the final width of the at least one protruding feature provided by the remaining hardmask material.
