300 nm to 20 µm-sized circular dots of SrBi 2 Ta 2 O 9 (SBT), lead-free ferroelectric materials, were fabricated by an electron-beam-induced micropatterning process using a scanning electron microscope (SEM)-based electron beam lithography system. The obtained micro dots were characterized using optical microscopy and atomic force microscopy. We also succeeded in fabrication of 2 to 20 µm diameter Ir/SBT/Ir circular capacitors employing a lift-off technique in the electron-beam-induced patterning process. Those circular capacitors showed piezoelectric response.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
