  • Patent number: 9058462
    Abstract: A system and method of producing an integrated circuit using abutted cells having shared polycrystalline silicon on an oxide definition region edge (PODE) includes modeling inter-cell leakage current in a plurality of different cells. Each of the plurality of different cells is abutted with another cell and having the shared PODE. The method also comprises verifying a pre-determined acceptable power consumption of the integrated circuit based on the inter-cell leakage current.
    Type: Grant
    Filed: August 30, 2013
    Date of Patent: June 16, 2015
    Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.

  • Patent number: 8826212
    Abstract: A method including developing a circuit schematic diagram, the circuit schematic diagram including a plurality of cells. The method further includes generating cell placement rules for the plurality of cells based on the circuit schematic diagram and developing a circuit layout diagram for the plurality of cells based on the cell placement rules. The method further includes grouping the plurality of cells of the circuit layout diagram based on threshold voltages and inserting threshold voltage compliant fillers into the circuit layout diagram. A system for implementing the method is described. A layout formed by the method is also described.
