发明名称 Selective shielding for multiple exposure masks
摘要 A system for preparing mask data to create a desired layout pattern on a wafer with a multiple exposure photolithographic printing system. In one embodiment, boundaries of features are expanded to create shields for those features, or portions thereof, that are not oriented in a direction that are printed with greater fidelity by an illumination pattern used in the multiple exposure printing system.
