This paper presents the results of numerical simulation of a microwave CVD
reactor operating in CW and pulsed regimes. Dependencies of discharge param
eters on the hydrogen pressure and microwave power have been studied. The p
ossibility to use the pulse-periodic regime of discharge for deposition of
diamond films has been analyzed. It is shown that a pulsed discharge may be
used to improve the quality and increase the growth rate of the films. (C)
