Patents by Inventor David A. PETERMANN

David A. PETERMANN 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).

  • Method of resolving color conflicts for cell-based designs with multi-pattern lithography
    Patent number: 10409947
    Abstract: According to one general aspect, a method may include receiving a data file that includes placement data regarding a plurality of circuit cells. The circuit cells may include respective layout portions. The layout portions may be associated with a plurality of respective lithographic colors. The method may include determining if a violating circuit cell is to be re-colored. The method may include indicating that, via at least one shape on a color swap layer in the data file, the violating circuit cell is to be at least partially re-colored. A color swap layer shape may cause a mask generator to re-color the portion of the violating circuit cell indicated by the color swap layer shape.
    Type: Grant

    Date of Patent: September 10, 2019
    Assignee: SAMSUNG ELECTRONICS CO., LTD.
    Inventors: David A. Petermann, Andrew P. Hoover, Chandrakanth Ramesh
  • Method of resolving multi-patterned color conflicts for multi-row logic cells
    Patent number: 10311194
    Abstract: According to one general aspect, a method may include dividing circuit cells into colorable sub-portions, wherein each circuit cell includes one or more colorable sub-portions. The method may include determining if a violating colorable sub-portion is to be re-colored. The method may include indicating that the violating colorable sub-portion is to be at least partially re-colored.
