    摘要: In a method for multiply exposing at least one substrate coated with a photosensitive layer, a first exposure is carried out in accordance with a first set of exposure parameters on a first projection system, and a second exposure is carried out in accordance with a second set of exposure parameters on a second projection system spatially separated from the first projection system. The projection systems are integrated in a common projection exposure installation. The first exposure can be carried out, for example, with an amplitude mask, the second exposure with a phase mask. The use of a number of projection systems enables multiple exposure that is performed in parallel and is therefore timesaving.

    摘要翻译: 在用感光层涂覆的至少一个基底进行多次曝光的方法中,根据第一投影系统上的第一组曝光参数进行第一曝光,并且根据第二组执行第二曝光 在与第一投影系统空间分离的第二投影系统上的曝光参数。 投影系统集成在通用投影曝光装置中。 第一曝光可以例如用幅度掩模进行,第二次曝光是用相位掩模进行的。 使用多个投影系统可以实现并行执行的多次曝光,因此节省时间。

    摘要: In a method for multiply exposing at least one substrate coated with a photosensitive layer, a first exposure is carried out in accordance with a first set of exposure parameters on a first projection system (17), and a second exposure is carried out in accordance with a second set of exposure parameters on a second projection system (18) spatially separated from the first projection system (17). The projection systems are integrated in a common projection exposure installation (1). The first exposure can be carried out, for example, with an amplitude mask (6), the second exposure with a phase mask (9). The use of a number of projection systems enables multiple exposure that is performed in parallel and is therefore timesaving.
