METHOD FOR OPERATING A PLURALITY OF FIB-SEM SYSTEMS

摘要

Processes may be performed with a plurality of FIB-SEM systems. A first process group includes recording an image with the electron beam column, depositing material with supply of a process gas, and performing ion beam etching. A second process group includes performing a sample exchange, exchanging a reservoir of a gas source for the process gas, and verifying an image that was recorded with the electron beam column. The processes of the second group are prioritized. The FIB-SEM systems are actuated to work through processes contained in process lists. If in a plurality of FIB-SEM systems processes of the second group are to be performed simultaneously, an instruction based on the prioritization is output to the user.
