摘要
用射频等离子体增强化学气相沉积(RF-PECVD)法制备氮掺杂氟化非晶碳(a-C:F)薄膜,用电桥测试薄膜的介电常数.研究不同工艺参量对薄膜电学性能的影响.结果表明:掺杂氮、高射频功率、高沉积温度以及热退火都导致薄膜介电常数上升.
Nitrogen doping fluorinated amorphous carbon (a-C : F) thin films are deposited using radio frequency plasma enhanced chemical vapor deposition (RF-PECVD). The films' dielectric constant is investigated by electric-bridge to study the deposited technical influence on the films. Nitrogen doping, high RF-power, high deposited temperature and thermal annealing can lead to high dielectric constant.
