为研究氧化依(IrO)对PZT铁电薄膜疲劳性能的影响,利用直流(DC)磁控反应溅射(sputtering)工艺成功地在SiO/Si(100)衬底上制得了高度取向的IrO薄膜.并在其上制成PZT铁电薄膜.讨论了溅射参数(溅射功率、 Ar/O比、衬底温度)以及退火条件对氧化铱薄膜的结晶、取向和形态的影响.

Iridium oxide (IrO2) thin films were successfully grown on SiO2/Si(100) substrate by a DC magnetron reactive sputtering method with an Ir target(99.9% purity).
PZT ferroelectric thin films were deposited by a sol-gel method. The as-deposited thin films were annealed with a thermal annealing process, after that the films
were highly directed at (110) or (200). The effect of sputtering parameters such as gun power, oxygen partial pressure (Ar/O2) and growth temperature
and annealing conditions on the crystalline nature and morphology of IrO2 thin films was discussed.
