Synthesis of Diamond-Like Carbon Films by R.F.Plasma CVD |
Abstract |
Diamond thin films were synthesized from the mixed gases of methane and hydrogen on silicon substrates by RF plasma chemical vapor deposition and deposited films were investigated by SEM, X-ray diffractometry and Raman spectroscopy. It is found that high quality diamond-like carbon films were successfully synthesized by PECVD under the deposition condition of 1-10 vol% of methane concentration, 0.15-0.4torr of reactor pressure, 500W of RF power, and 5-20hr of reaction time. Especially, cubo-octahedral diamond-like carbon particles were synthesized by employing 1.0 vol % of methane concentration and 0.4torr of the reactor pressure. |
