摘要:
A NaCl oxide thin layer oriented to (100) face or a spinel oxide thin layer oriented to (100) face, a perovskite dielectric thin layer oriented to (100) face and a metal electrode are sequentially laminated on a metal electrode, thus providing a thin film capacitor. Or alternatively, a thin film capacitor is manufactured by sequentially laminating a NaCl oxide thin layer oriented to (100) face or a spinel oxide thin layer oriented to (100) face, a platinum thin layer as a lower electrode oriented to (100) face, a perovskite dielectric thin layer oriented to (100) face and a metal thin layer as an upper electrode on a substrate. A plasma-enhanced CVD method is applied to form a NaCl oxide thin layer, a spinel oxide thin layer and a perovskite dielectric thin layer while a vacuum deposition method, a sputtering method, a CVD method or a plasma-enhanced CVD method is applied for the formation of a metal electrode.
