发明名称 Tandem microchannel plate and solid state electron detector
摘要 A compact detector for secondary and backscattered electrons in a scanning electron beam system includes a microchannel plate detector and a solid state detector connected in a tandem manner. The detector offers large bandwidth and high dynamic range. The detector can be used for article inspection, lithography, metrology, and other related applications. The compactness of the detector makes it ideally suited for utilization in a miniature electron beam column, such as a microcolumn.
