    摘要: Provided is a method of fabricating a photo mask. The method includes preparing a model group including optical proximity correction (OPC) models and generating a preliminary mask layout using an integrated circuit (IC) layout. A contour image may be produced from the preliminary mask layout through a simulation using an optical model. Subsequently, the preliminary mask layout may be compared with the contour image and the comparison result may be analyzed to produce analysis data for providing criteria used in selecting an OPC model. An OPC model suitable for the preliminary mask layout may be selected from the model group based on the analysis data. An OPC process may be performed on the preliminary mask layout using the selected OPC model to generate a mask layout.

    摘要: A pattern arrangement method of a semiconductor device is provided. In the pattern arrangement method, patterns are classified according to effective pitches and critical dimensions, and pattern dispersion is predicted according to the effective pitches and the critical dimensions by using a statistical analysis of process parameters. Two-dimensional coordinates of the effective pitches and the critical dimensions are constructed, and a dispersion map is made by arranging the predicted pattern dispersion on the corresponding coordinates. By arranging design patterns within a tolerance region of the dispersion map, the patterns satisfying the dispersion tolerance according to the significance of the layer and the design requirements can be arranged.
