Patents by Inventor Chien-Hsiung Wang

Chien-Hsiung Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9530731
    Abstract: A method of optical proximity correction executed by a computer system for modifying line patterns includes the following steps. First, providing an integrated circuit layout with parallel line patterns and interconnect patterns disposed corresponding to the parallel line patterns. Then, using the computer to modify the integrated circuit layout based on a position of the interconnect patterns so as to generate a convex portion and a concave portion respectively on two sides of each of the parallel line patterns. Portions of the line pattern in front of and behind the convex portion and the concave portion are straight lines and have an identical critical dimension.
    Type: Grant

  • Publication number: 20060168769
    Abstract: A button structure includes a flexible body, a protective layer and a hard frame. The protective layer has a plurality of pictures and symbols formed on a rear face thereof, and is formed on a top side of the flexible body for protecting the pictures and symbols and making the pictures and the symbols wear resistant. The hard frame is disposed under the flexible body for increasing the rigidity of the flexible body and retaining the shape of the flexible body. Therefore, the present invention not only solves the conventional problems that the pictures or symbols are easily worn and stripped from the flexible body and that the flexible body is not easily positioned when in use, but it also reduces the volume of the button structure by disposing the hard frame under the flexible body.
