Abstract

We present a model of an ECR plasma in a cylindrical (z, r) geometry with resonant zone near the substrate surface. The model combines a hybrid (particle ion-fluid electron) treatment of plasma transport with an ad-hoc model of microwave power deposition. The model is used to test the effect of the radial profile of microwave power on the spatial profiles of plasma parameters: plasma density, plasma potential and electron temperature. It is shown that for uniformity of ion flux at the substrate surface, microwave power must be peaked off axis.
