摘要:
The invention relates to a particle beam device (1, 24) having a detector arrangement. The particle beam device (1, 24) has a first particle beam column (16), the first particle beam column (16) having a first beam generator for generating a first particle beam, and a first objective lens for focusing the first particle beam on an object (11). The first particle beam column (16) has a first beam axis (28). In addition, a second particle beam column (2) is provided, the second particle beam column (2) having a second beam generator for generating a second particle beam, and a second objective lens for focusing the second particle beam on an object (11). The second particle beam column (2) has a second beam axis (29). A detector (12) is provided for detecting interacting particles and/or interacting radiation. A detection axis (33) extends from the detector (12) to an object (11). The first beam axis (28) of the first particle beam column (16) and the second beam axis (29) of the second particle beam column (2) define a first angle (Φ) which is different from 0° and from 180°. In addition, the first beam axis (28) of the first particle beam column (16) and the second beam axis (29) of the second particle beam column (2) are situated in a first plane (32). The detection axis (33) of the detector (12) and the first beam axis (28) are situated in a second plane (34). Furthermore, the first plane (32) and the second plane (34) define a second angle (α) having an absolute value in the range of 65° to 80°.
摘要:
A method of processing of an object comprises scanning a particle beam across a surface of the object and detecting electrons emerging from the object due to the scanning (103,105); determining a height difference between the surface of the object and a predetermined surface for each of plural of locations on the surface of the object based on the detected electrons (107); determining a processing intensity for each of the plural locations on the surface of the object based on the determined height differences; and directing a particle beam to the plural locations based on the determined processing intensities, in order to remove material from or deposit material on the object at the plural locations (113).
