| 摘 要： | 在苯(C6H6)和四氟化碳(CF4)混合气体中,用微波电子回旋共振等离子体化学气相沉积技术(ECRCVD)在不同功率下制备了氟化非晶碳膜(aC:F),为了检测膜的热稳定性对其进行了真空退火处理,测量了退火前后膜厚的变化率,并用傅里叶变换红外吸收光谱(FTIR)研究了其结构的变化.结果表明,膜厚变化率与沉积功率有关;400℃退火后低功率下沉积的膜的结构变化显著,高功率下沉积的膜则呈现了较好的热稳定性.

| Abstract: | a-C:F films were deposited by electron cyclotron resonance plasma chemical vapor deposition (ECR-CVD) using CF-4 and C-6H-6 as source gases. In order to investigate the thermal stability, the films have been annealed in vacuum at several temperatures. The film thicknesses before and after annealing were measured, and the structures were analyzed using Fourier-transformed infrared spectrometer(FTIR) spectra. It shows that after annealing the films become thinner and the structures of the films deposited at lower microwave powers have more changes than ones of the films deposited at higher microwave powers. It means that the films prepared at higher microwave powers have better thermal stability. |
