It has wide applications in photoelectric device, bio-technology, mechanics, and aviation engineering. In order to deposit diamond thin film on P type (100) silicon substrate, we use microwave plasma enhanced chemical vapor deposition (MPECVD) to control the deposition environment in low temperature and pressure. In this research, the different condition was investigated for treating the substrate: non-pretreatment and pretreatment. We compare the resulting diamond film deposited under different conditions and analyze them with the optical microscopy and XRD to find the better process parameters. 1 微波電漿化學氣相沉積法於矽基材上成長鑽石薄膜 Keywords : Diamond film, Microwave plasma chemical vapor deposit
