Vol. 7, Issue 2, Pages: 67-72(1999)

Abstract：In this paper we report the reactive ion etching(RIE)of quartz by using CHF₃ 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 CHF₃ 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.

Abstract：It is a very difficult problem to simulate ball bearing in structural analysis or in the finite element analysis correctly . Because the working condition of the ball bearing is very complex, the boundery conditions of the balls 、inner and outer rings of the ball bearing are difficult to define. The static and dynamic analysis of ball bearing is carried and the simplifying method of the ball bearing is studied with the finite element analysis program-Ansys.
