摘要: 本文利用射频磁控溅射工艺制备了SiCN薄膜,研究了基本工艺参数如溅射功率、N分压对薄膜沉积和光学性能的影响.研究结果表明:溅射制备的薄膜中形成了复杂的网络结构,膜中三元素Si、C和N两两之间形成了共价键.N分压的提高降低了薄膜的沉积速率.N流量的提高使光学带隙增大.溅射功率的提高使薄膜的沉积速率提高,但使得光学带隙减小.

关键词: SiCN薄膜, 磁控溅射, FTIR, 光学带隙

Abstract: iCN films were prepared by RF magnetron sputtering with SiC target. The influences of the basic
process parameters, such as the deposition power and partial pressure of nitrogen, on the deposition rate and optical properties were studied.
XPS and FTIR results revealed the formation of a complex network among Si, C and N. The deposition rate decreased with increasing partial
pressure of nitrogen. The increase of N flux resulted in wider optical gap. The higher the deposition power, the higher the deposition rate
and the narrower the optical band gap.

Key words: SiCN films, RF magnetron sputtering, FTIR, optical band gap
