用于检查的方法和设备
Abstract:
本发明公开了一种电子束检查设备，该设备包括：多个电子束柱(600)，每个电子束柱配置成提供电子束且检测来自物体的散射电子或二次电子；和致动器系统(600，610)，其配置成使所述电子束柱中的一个或更多个相对于所述电子束柱中的另外的一个或更多个移动(640，630)。所述致动器系统可包括多个第一可移动结构，所述多个第一可移动结构与多个第二可移动结构至少部分地重叠，所述第一可移动结构和所述第二可移动结构支撑所述多个电子束柱。
Abstract(English):

An electron beam inspection apparatus is disclosed, the apparatus including a plurality of electron beam columns (600), each electron beam column configured to provide an electron beam and detect scattered or secondary electrons from an object, and an actuator system (600, 610) configured to move (640, 630) one or more of the electron beam columns relative to another one or more of the electron beam columns. The actuator system may include a plurality of first movable structures at least partly overlapping a plurality of second movable structures, the first and second movable structures supporting the plurality of electron beam columns.
