The Zeiss LEO 1550VP is a high-performance Scanning Electron Microscope (SEM) equipped with a Schottky type field emission gun, various detectors (in-lens and chamber-mount secondary electron detectors, detector for energy-dispersive x-ray analysis), and e-beam patterning system. A close relative to the LEO 1530 SEMs in the NIAC, this system is positioned as having a cleaner chamber and better vacuum to optimize the performance for contamination sensitive samples (for example, low contrast self-assembled block-copolymer coatings) and high-resolution patterning. To ensure the clean environment, the SEM is equipped with air lock system for sample exchange without opening the main chamber on atmosphere.
This is an accordion element with a series of buttons that open and close related content panels.
