Abstract
Ferroelectric SrBi 2 Ta 2 O 9 (SBT) thin films were deposited by RF magnetron sputtering on a Pt/Ti/SiO 2 /Si(100) structure. The deposition temperature of the film was varied from RT (room temperature) to 600C. It was found that the SBT films were crystallized at temperatures between 500C and 600C, which was much lower than the annealing temperature (700C to 800C) of the RT-deposited film. The maximum remnant polarization value (2Pr) of the SBT film was 15 w C/cm 2 , which was deposited at 575C.
