摘要:
A method is provided of reducing the thickness of a region of a target sample. Reference data is obtained that is representative of x-rays generated by a particle beam being directed upon part of a reference sample under a first set of beam conditions. Under a second set of beam conditions the particle beam is directed upon the region of the target sample. The resultant x-rays are monitored as monitored data. Output data are then calculated based upon the reference and the monitored data. Material is then removed from the region, so as to reduce its thickness, in accordance with the output data.
摘要(中):
提供了减少目标样品的区域的厚度的方法。 获得参考数据,其代表由在第一组光束条件下被引导到参考样本的一部分的粒子束产生的x射线。 在第二组光束条件下,粒子束被引导到目标样品的区域。 作为监测数据监测所得X射线。 然后根据参考和监视数据计算输出数据。 然后根据输出数据从该区域移除材料,以便减小其厚度。
