Abstract:The processing technology and dielectric properties of(Ba,Sr)TiO_3(BST) thin films have been widely studied because of its promising application as dielectric materials in the fields of microelectronics and microelectromechanical system(MEMS),etc.The processing technology determines the dielectric properties(dielectric constant, leakage current density,dielectric strength,etc.) of BST thin films.This paper make a review in some key problems in the preparation technology of BST thin films by RF magnetron reactive sputtering deposition,such as preparation of BST target,optimization of processing parameter,control of thin films composition,and the effects of processing parameters on dielectric properties,etc.
Keywords:barium strontium titanate ceramic  RF magnetron sputter deposition  dielectric properties  stoichiometry  microstructure  postdeposition annealing
