    • PROBLEM TO BE SOLVED: To provide an optical image-forming system for test microscopes in which a lithography mask can inspect defects by the help of an inspection microscope having a large magnification although the lithography mask is in a structure that continues to shrink and at an image formation side NA of an image-forming system that continues to expand, and the real image of the scanner system can test errors by the emulation of especially a large-diameter scanner system for creating emulation having an appearing vector effect. SOLUTION: The image-forming system for emulating the large-diameter scanner system comprises an image-forming optical system, a detector, and an evaluation unit. An optical component having at least one polarization effect is arranged according to a selection for picking out diversified polarization components x, y, z for image formation radiation in an image formation optical path. The optical components having an intensity attenuation function can be brought into the image formation optical path. An image is captured by a detector for radiation components in which mask and/or sample images are polarized diversely for further guiding for further processing to the evaluation unit.

    • 要解决的问题:为了提供用于测试显微镜的光学成像系统,其中光刻掩模可以借助具有大放大率的检查显微镜来检测缺陷,尽管光刻掩模处于继续收缩的结构 并且在图像形成系统的图像形成侧NA继续扩展,并且扫描仪系统的真实图像可以通过特别是用于创建具有出现的矢量效应的仿真的大直径扫描器系统的仿真来测试误差。 解决方案:用于模拟大直径扫描器系统的图像形成系统包括成像光学系统,检测器和评估单元。 具有至少一种偏振效应的光学部件根据用于选择图像形成光路中的图像形成用射线的多种偏振分量x,y,z的选择来配置。 具有强度衰减功能的光学部件可以被带入图像形成光路。 由用于辐射成分的检测器捕获图像,其中掩模和/或样品图像被不同地偏振,以进一步引导以进一步处理到评估单元。 版权所有(C)2006,JPO&NCIPI
