摘要:
One embodiment relates to a method of automated inspection of scattered hot spot areas on a manufactured substrate using an electron beam apparatus. A stage holding the substrate is moved along a swath path so as to move a field of view of the electron beam apparatus such that the moving field of view covers a target area on the substrate. Off-axis imaging of the hot spot areas within the moving field of view is performed. A number of hot spot areas within the moving field of view may be determined, and the speed of the stage movement may be adjusted based on the number of hot spot areas within the moving field of view. Another embodiment relates to an electron beam apparatus for inspecting scattered areas on a manufactured substrate. Other embodiments, aspects and features are also disclosed.
摘要(中):
一个实施例涉及一种使用电子束设备自动检查制造的衬底上的散射热点区域的方法。 保持基板的台沿着扫描路径移动,以移动电子束设备的视场,使得移动的视场覆盖基板上的目标区域。 执行移动视场内的热点区域的离轴成像。 可以确定移动视场内的多个热点区域,并且可以基于移动视场内的热点区域的数量来调整舞台移动的速度。 另一实施例涉及一种用于检查制造基板上的散射区域的电子束设备。 其他实施例,方面和特征也被公开。
