FEI Strata 235DB

The FEI Strata 235DB is a dual beam FIB/ SEM system equipped with multiple electron detectors, and also includes a secondary ion detector. The system has a digital scan board to help with complex milling patterns and it also has electron and ion beam lithography capability. The FIB has a 4 cartridge gas injection system (GIS) for either enhanced etching, or deposition of metal/insulator for protection layers and/or circuit editing.
