The Thermo Scientific™ V400ACE™ Focused Ion Beam (FIB) system is specifically designed to meet the challenges of advanced designs and processes: smaller geometries, higher circuit densities, exotic materials, and complex interconnect structures. The V400ACE FIB can be configured for backside editing with an optional IR microscope and bulk silicon trenching package. Thermo Scientific™ Tomahawk™ Ion Column delivers unrivalled capability and flexibility with seamless operation from 30 kV to 2 kV. High current density milling at 30 kV ensures rapid material removal and increased throughput, while low-kV operation is useful for selective etching of copper. FIB circuit editing tools use controlled amounts of specific gases, injected near the beam at the sample surface, to enhance the speed and selectivity of the milling process and to deposit conductive and insulating materials in precisely controlled patterns.
