  • Patent number: 10078718
    Abstract: Disclosed is a method of fabricating an integrated circuit (IC) using a multiple (N>2) patterning technique. The method provides a layout of the IC having a set of IC features. The method further includes deriving a graph from the layout, the graph having vertices connected by edges, the vertices representing the IC features, and the edges representing spacing between the IC features. The method further includes selecting vertices, wherein the selected vertices are not directly connected by an edge, and share at least one neighboring vertex that is connected by N edges. The method further includes using a computerized IC tool to merge the selected vertices, thereby reducing a number of edges connecting the neighboring vertex to be below N. The method further includes removing a portion of the vertices that are connected by less than N edges.

  • Publication number: 20180149980
    Abstract: An electron-beam lithography method includes, computing and outputting a development time of a positive-tone electron-sensitive layer and a parameter recipe of an electron-beam device by using a pattern dimension simulation system, performing a low-temperature treatment to chill a developer solution, utilizing an electron-beam to irradiate an exposure region of the positive-tone electron-sensitive layer based on the parameter recipe, and utilizing the chilled developer solution to develop a development region of the positive-tone electron-sensitive layer based on the development time. The development region is present within the exposure region, and an area of the exposure region is smaller than that of the first portion. As a result, the electron-beam lithography method may control a dimension of a development pattern of the positive-tone electron-sensitive layer more accurately, and may also shrink a minimum dimension of the development pattern of the positive-tone electron-sensitive layer.

  • Patent number: 9979952
    Abstract: A method for creating a parallax video from a still image includes following steps. Image segmentation is performed for separating at least a foreground object within the still image from an image background of the still image. A blank region of the image background is filled, and the blank region corresponds to where the separated foreground object locates within the still image. A virtual three-dimensional (3D) scene consisting of the foreground object and the image background is created. The virtual 3D scene is analyzed for determining a camera path; and, creating the parallax video by observing the virtual 3D scene with a virtual camera moving along the camera path.
