    • Some embodiments of the invention provide a process for designing and manufacturing an integrated circuit (“IC”). The process selects a wiring configuration and an illumination configuration. The process uses the selected wiring configuration to design an IC layout. The process then uses the selected illumination configuration to manufacture the IC based on the designed IC layout. Some embodiments concurrently select an optimal pair of wiring and illumination configurations. Other embodiments select an illumination configuration based on the selected wiring configuration. Yet other embodiments select a wiring configuration based on the selected illumination configuration. In some embodiments, selecting the illumination configuration entails selecting at least one stepper lens for the IC layout, where the stepper lens illuminates at least one mask for at least one particular layer of the IC layout. In some embodiments, this selection entails selecting a stepper lens for each particular layer of the IC layout. Also, in some embodiments, selecting the wiring configuration entails defining the width and/or spacing of the routes along different directions on at least one particular wiring layer of the IC layout. In some embodiments, this selection entails selecting width and/or spacing of routes along different directions on each particular layer of the IC layout.
    • 本发明的一些实施例提供了一种用于设计和制造集成电路(IC)的方法。 该过程选择接线配置和照明配置。 该过程使用选定的接线配置来设计IC布局。 然后,该过程使用所选择的照明配置来基于设计的IC布局来制造IC。 一些实施例同时选择一对最佳布线和照明配置。 其他实施例基于所选择的布线配置来选择照明配置。 其他实施例基于所选择的照明配置来选择布线配置。 在一些实施例中,选择照明配置需要为IC布局选择至少一个步进透镜,其中步进透镜照亮IC布局的至少一个特定层的至少一个掩模。 在一些实施例中,该选择需要为IC布局的每个特定层选择步进透镜。 此外,在一些实施例中,选择布线配置需要在IC布局的至少一个特定布线层上限定沿着不同方向的路线的宽度和/或间隔。 在一些实施例中,该选择需要选择在IC布局的每个特定层上沿不同方向的路线的宽度和/或间隔。
