    • A method of operating a projection exposure tool (10) for microlithography is provided. The projection exposure tool (10) has a projection objective (26) for imaging object structures on a mask (20) into an image plane (28) using electromagnetic radiation (13, 13a, 13b), during which imaging the electromagnetic radiation (13b) causes a change in optical properties of the projection objective (26). The method comprises the steps of: providing the layout of the object structures on the mask (20) to be imaged and classifying the object structures according to their type of structure, calculating the change in the optical properties of the projection objective (26) effected during the imaging process on the basis of the classification of the object structures, and using the projection exposure tool (10) for imaging the object structures into the image plane (28), wherein the imaging behavior of the projection exposure tool (10) is adjusted on the basis of the calculated change of the optical properties in order to at least partly compensate for the change of the optical properties of the projection objective (26) caused by the electromagnetic radiation (13, 13a, 13b) during the imaging process.
    • 提供了一种操作用于微光刻的投影曝光工具(10)的方法。 投影曝光工具(10)具有用于使用电磁辐射(13,13a,13b)将掩模(20)上的物体结构成像到图像平面(28)中的投影物镜(26),在此期间对电磁辐射(13b)进行成像 )导致投影物镜(26)的光学特性的变化。 该方法包括以下步骤:在要成像的掩模(20)上提供对象结构的布局,并根据其结构类型对对象结构进行分类,计算投影物镜(26)的光学特性的变化 在所述成像处理期间,基于所述物体结构的分类,以及使用所述投影曝光工具(10)将所述物体结构成像到所述图像平面(28)中,其中所述投影曝光工具(10)的成像特性为 基于所计算的光学特性的变化进行调整,以至少部分地补偿由成像过程中的电磁辐射(13,13a,13b)引起的投影物镜(26)的光学特性的变化。
