Pecvd roughness
WebIn this paper we study the effect of H 2 /SiH 4 dilution ratio (R) on the structural and optical properties of hydrogenated microcrystalline silicon embedded in amorphous matrix thin films. The thin films are prepared using standard RF-PECVD process at substrate temperature of 200 °C. Webenhanced chemical vapor deposition (PECVD) for the application of microelectronics, optoelectronics and MEMS. The film quality depends on the deposition methods including chemical vapor deposition, e.g. PECVD [1–5], and physical vapor deposition (PVD), e.g. sputtering [6–8]. In general, a-Si films are preferred to be deposited by PECVD rather
