Abstract

We investigate uniformity of radial density profile of nano-particles in capacitively-coupled radio frequency discharge with an amplitude modulation (AM) of rf discharge voltage, by a two-dimensional laser light scattering method. Their densities at the center and that at the edge of the electrode increase by 3 and 24 times when the amplitude modulation level increases from 0 (without AM) to 30%. The uniformity of radial density profile of nano-particles is significantly improved by using the AM method.
