摘要： Model Based Optical Proximity Correction (MOPC) biasing techniques may be utilized for optimizing a mask pattern. However, conventional MOPC techniques do not account for influence from neighboring features on a mask. This influence may be factored in the following manner—first, generating a predicted pattern from a target pattern and selecting a plurality of evaluation points at which biasing may be determined. Next, a set of multivariable equations are generated for each evaluation point, each equation representing influence of neighboring features on a mask. The equations are solved to determine that amount of bias at each evaluation point, and the mask is optimized accordingly. This process may be repeated until the mask pattern is further optimized.
摘要翻译：基于模型的光学邻近校正（MOPC）偏置技术可用于优化掩模图案。然而，传统的MOPC技术不能解释掩模上相邻特征的影响。这种影响可以以以下方式考虑：首先，从目标图案生成预测图案，并且选择可以确定偏置的多个评估点。接下来，为每个评估点生成一组多变量方程，每个方程表示相邻特征对掩模的影响。求解等式以确定每个评估点的偏差量，并相应地优化掩模。可以重复该过程，直到掩模图案进一步优化。

摘要： A lithographic apparatus comprises an illumination system for providing a projection beam of radiation, a support structure for supporting patterning device, the patterning device serving to transmit or reflect radiation in the projection beam and impart the projection beam with a pattern in its cross-section, a substrate table for holding a substrate, and a projection system for projecting the patterned beam onto a target portion of the substrate. A sensor is provided for measuring the spatial intensity distribution of the projection beam at the substrate. The spatial distribution of transmission or reflectance of the patterning device, together with the distribution of the projection beam incident on the patterning device, may be determined from the measured intensity distribution. By comparing the transmission or reflectance from regions having identical patterns the overall (macroscopic) distribution of the transmission or reflectance of the patterning device can be determined.
