中国科学院大连化学物理研究所专利：一种磁控溅射低温制备TiN薄膜的方法
中国科学院大连化学物理研究所 专利 磁控溅射 低温 TiN薄膜
font style='font-size:12px;'>
2023/9/5
本发明涉及一种反应磁控溅射低温制备TiN薄膜的方法，通过对传统磁控溅射技术的改进，在真空室内引入一等离子体区域，采用中频脉冲直流或直流溅射溅射Ti金属靶，并控制工作气体压强、温度、时间、溅射功率等工艺条件，在衬底上沉积TiN薄膜。使用本方法可以在低温环境下性能良好的TiN薄膜，薄膜的结晶度、致密性及硬度得到提高，表面粗糙度小，薄膜与衬底有较高的结合力，很难产生局部脱落。本发明可以为硬质薄膜的实验研...
