摘要
High density plasma etching of ultrananocrystalline diamond (UNCD) films was performed in O-2 and O-2/Ar inductively coupled plasma (ICP) discharges. The O-2/Ar ICP discharges produced higher etch rates due to enhanced physical component of the etching, and a maximum etch rate of similar to 280 nnn/min was obtained in 10 sccm O-2/5 sccm Ar discharges. Very high etch selectivities up to similar to 140:1 were obtained for the UNCD over Al mask layer. Anisotropic pattern transfer with a vertical sidewall profile was achieved in the 10 scorn O-2/5 scorn Ar discharges at a relatively low source power (300 W) and a moderate rf chuck power (200 W).
