WebFocused ion beam (FIB) milling is a mask-free lithography technique that allows the precise shaping of 3D materials on the micron and sub-micron scale. The recent discovery of electronic nematicity in La2−xSrxCuO4 (LSCO) thin films triggered the search for the same phenomenon in bulk LSCO crystals. With this motivation, we have systematically … Webespecially for lithography mask metrology, for example. The masks involved are exposed to EUV light (13.5 nm) in advanced lithography scanners and project the structures in the mask onto a wafer. If they contain defects, these are transferred via the EUV light to the wafer and could potentially ruin the product. Therefore, one would ideally iris clean room
