Influence of target self-bias in inverted cylindrical RF sputtering on the microstructure and electrical properties of Ba_(0.65)Sr_(0.35)TiO_3 thin films;
倒筒式射频溅射自偏压对Ba_(0.65)Sr_(0.35)TiO_3热释电薄膜结构及性能的影响
(Ba,Sr)TiO_3 (BST) thin film is one of the ideal materials applied for Uncooled Focal Plane Array (UFPA) due to its high dielectric constant, low leakage current, good pyroelectric property, the preparation of BST thin film based on inverted cylindrical RF sputtering was studied in this thesis.
为了满足单片式UFPA器件研制的需要,本文开展了BST薄膜的倒筒靶射频(RF)溅射生长研究:首先进行了筒形BST陶瓷靶的烧结工艺研究,在优化烧结条件下制得结构致密,结晶良好的Ba_(0。
