Ar ion beam etching and inductively coupled SF{sub 6} and C{sub 4}F{sub 8} plasma-etching processes have been employed to fabricate free standing membrane from the heteroepitaxial La{sub 1-x}(Sr,Ca){sub x}MnO{sub 3}(50 nm)/Bi{sub 4}Ti{sub 3}O{sub 12}(100 nm)/CeO{sub 2}(40 nm)/YSZ(30 nm) film structure pulsed laser deposited on Si(001) wafer. We demonstrate feasibility to use epitaxial colossal magnetoresistive manganite film as thermally isolated self-supporting membrane for uncooled infrared microbolometer applications.
