  • Patent number: 9367655
    Abstract: The present disclosure provides a method. The method includes obtaining an integrated circuit (IC) layout. The method includes providing a polishing process simulation model. The method includes performing a lithography pattern check (LPC) process to the IC layout. The LPC process is performed at least in part using the polishing process simulation model. The method includes detecting, in response to the LPC process, possible problem areas on the IC layout. The method includes modifying the polishing process simulation model. The method includes repeating the performing the LPC process and the detecting the possible problem areas using the modified polishing process simulation model.

  • Patent number: 9141745
    Abstract: A method includes providing a first layout of a semiconductor device comprising a plurality of cells representing circuit elements, and providing a cell library comprising a plurality of cells in a processor. The circuit elements comprise a plurality of fin field effect transistors (Fin-FETs). Each of the plurality of cells in the cell library is displayed with a respectively different marker indicating a respective fin height. The method further includes generating a second layout for the semiconductor device to be fabricated, by placing or replacing at least one cell from the cell library in a respective location in the first layout. The at least one cell from the cell library comprises a Fin-FET with a respective fin height different from an adjacent Fin-FET in the second layout.

  • Patent number: 9122836
    Abstract: Apparatus includes a machine readable storage medium for storing a template library having at least one template. The template is to include a first layout representation of at least one pattern to be formed by multi-patterning a single layer of an IC. The pattern has a plurality of portions to be formed using a plurality of respectively different photomasks. The first layout representation includes data identifying on which photomask each portion is to be located. An electronic design automation (EDA) tool includes a processor configured to receive a hardware description language representation of at least a part of a circuit and generate a second layout representation of the part of the circuit having a plurality of polygons. The EDA tool has a matching module that identifies and outputs an indication of whether one or more of the plurality of portions matches a subset of the plurality of polygons.
