采用热丝法沉积金刚石膜.分离送入氢气和甲烷.使作为发热体的钨丝电阻值比经典的热丝法降低20%.用此法制得的金刚石晶形较好.实验表明:反应气体的流量对膜的致密生长区影响很大.
HFCVD metliod was employed to deposit diamond film on silicon substrate. The design of in-letting H2 and CH4 separetely was applied, which made the resistanee of tungsten filament dccrease to 20%,compared to that of HFCVD with mixture inletting. Moreover,
