摘要 用热丝法沉积金刚石膜,分离送入氢气和甲烷,可以减少钨丝碳化,提高功率利用率分送与混进相结合,可以制备晶体形态良好的金刚石膜到达基材表面的活性粒子的数量是提高金刚石膜生长速率的关键生长速率可达 3.8μm/h,均匀区面积达 In the research of deposition diamond film by HFCVD, the method of inlet CH4 and Hi separate could reduce the carbonation of tungsten filament and raise the efficiency of using power. The combination of mixed and separate inlet of CH4 and HZ can get well-faced crystal of diamond. The crux of increasing the growth rate of diamond film is to increase the quantity of active species to the substrate surface per unit area. The growth rate of 3.8μm/h and even area of 400mm2 were obtained.
