  • 采用射频反应磁控溅射法用高纯石墨作靶、三氟甲烷(CHF3)和氩气(Ar)作源气体制 备了氟化类金刚石(FDLC)薄膜,通过XPS光谱结合拉曼光谱、红外透射光谱和紫外可见光光谱研究了源气体流量比等工艺条件对薄膜中键结构、sp2/sp3杂化比以及光学带隙等性能的影响.结果表明在低功率(60W)、高气压(2.0Pa)和适当的流量比(Ar/CHF3=2∶ 1)下利用射频反应磁控溅射法可制备出氟含量高且具有较宽光学带隙和超低介电常数的FDLC薄膜.
    Fluorinated diamond_like carbon(F_DLC) films were prepared by radio frequency(RF) reactive magnetron sputtering with trifluoromethane (CHF3) and argon as source gases, and pure graphite as a targ et. The influence of source gas flow rate ratio on the film bonding configuration, sp2/sp3 hybrid ratios and optical band gap were investigated by Raman, Infrared transmission spectra, UV_visible spectra and XPS spectra. The results show that F-DLC films with high fluorine content, wide optical band gap and ultra-low diel ectric constant can be prepared by RF reactive magnetron sputtering technique in low input RF power (60W), high pressure (2.0Pa) and proper sour ce gas flow ratio (Ar/CHF3=2∶1).
