| 摘 要： | 本工作开发了一种靶电压反馈自动控制系统,称为可编程控制器(PLC)级差法反馈控制系统,用于旋转圆柱金属Al靶真空反应溅射沉积Al2O3陶瓷薄膜。根据反应溅射Al2O3工艺特性设计反馈控制的数学模型,再按照数学模型,采用梯形语言在PLC内进行程序编码实现。通过反馈控制参数的优化,实现较高功率26 kW下中频磁控反应溅射Al2O3工艺稳定。测试得到50 nm厚的Al2O3薄膜,其可见光吸收比和太阳光吸收比接近零。这种反应溅射反馈控制系统简易可行且经济实用。

| Abstract: | A graded PLC closed-loop feedback control system was developed for target voltage and the system has successfully been applied to the deposition of Al2O3 ceramic films by MF reactive magnetron sputtering with rotating cylindrical metallic Al target.A mathematical model of feedback control was developed according to the characteristics of the reactive magnetron sputtering process for Al2O3 films.Then,the feedback control involved in the model was implemented through the trapezoidel language which was applied... |
