Abstract
In this paper we report the reactive ion etching(RIE)of quartz by using CHF
3
and argon.The effects of gas flow rate
chamber pressure
and rf(radio frequency)plasma power on the etch rate were investigated and the surface contamination due to RIE was examined.The quartz etch depth uniformity and repeatability was also examined.In order to optimise the etch process
the RS1/Discover software tool was used to design the experiments.The rf plasma power varied between 120 and 160 watts.Argon and CHF
3
flow rates were 15-35 sccm and 20-50 sccm respectively
and pressure was in the range of 13-19 Pa.The etch rate varied between 15 and 25 nm/min.
