    • A resist flow process modeling algorithm for optic lithography modeling is provided to generate an accurate lithography model by extracting precisely parameters of elements generated from measurement patterns. To determine an optimum resist flow model, a model adjusted on a process and a target pattern is determined using a lithography system having a resist unit level process. A PEB(Position Error Bound) parameter extracting algorithm on a target pattern for test is selected using the process. Plural diffraction engineering elements are selected. The test pattern is optimized and a corresponding wave length is selected. Then, an algorithm for determining parameters is executed according to the selection based on plural polarization effects. By selecting optimum one of the diffraction engineering elements, a final lithography model is obtained.

    • A lithography process for forming a specific pattern is provided to form a desired pattern by controlling properly a stacked structure of semiconductors. A lithography process is performed to form a desired shape of pattern on a wafer(1) in a semiconductor manufacturing process. A first and second semiconductors(2,3) are stacked in a vertical direction. The desired shape of pattern is easily obtained by applying different etch processes according to optical contrast characteristics of each semiconductor. The first and second semiconductors are formed by controlling properly etch ratios according to refractive indexes and diffractive indexes. The first and second semiconductors have different optical contrasts or similar optical contrasts.
