Abstract:
A method for forming an SBT ferroelectric thin film, comprising the steps of:evaporating source materials comprising Sr(C.sub.5 F.sub.6 HO.sub.2).sub.2, Bi(C.sub.6 H.sub.5).sub.3, and Ta(C.sub.2 H.sub.5 O).sub.5 ;carrying said source materials to a chamber by carrier gas;charging a reaction gas in said chamber while maintaining said chamber at an operating pressure enough to generate plasma;generating plasma by an RF power generator at an RF power of approximately 100-150 W to carry out deposit at a low temperature; anddepositing said source materials on a substrate at a temperature of approximately 500-550.degree.
