"I have been working on Quanta 400 & 600 Series SEM's for the past 5 years, the latter 3 on two 650FEG's. These are excellent tools, which puts 2 different FEG's I have used in this same timespan to utter shame. In the 3 categories, I would give the 650F 5, 5 and 4 marks respectively. Likewise, the 400 tungsten tools are excellent SEMS. They have been the best platform, bar none, on the MLA and QemSCAN technologies."
