Abstract: Umeå Centre for Electron Microscopy (UCEM) is an open-access, national facility that provides education and training in electron microscopy techniques for structural and chemical characterization of materials at micro- and nanometer length scale. The facility houses many state-of-the-art instrumentations such as scanning electron microscopes, transmission electron microscopes and focused ion beam microscope.
Focused ion beam-scanning electron beam microscopy (FIB-SEM) is a cutting-edge technology for manipulating materials at sub-micrometer scale with high-precision and high-accuracy at both room- and cryogenic temperatures. By using heavy ions such as gallium, materials can be locally removed and shaped into desired patterns and dimensions. By using electrons, the imaging of the materials removal process and sample surface can be effortlessly achieved.
Together with sophisticated stage positioning, gas injection system and micromanipulator, there are vast applications of the FIB-SEM method, such as preparation of thin sections (lamellae) for transmission electron microscopy (TEM) imaging, fabrication of micro- and nanometer devices and creation high-resolution 3-dimensional reconstructions of materials and biological samples.
