Abstract

A microwave plasma rector is disclosed comprising a vacuum chamber, a microwave generator for generating a microwave standing wave therein, inlet and outlet ports, a susceptor within the chamber, at least one dielectric plate and a heater for heating the susceptor. The dielectric plate alters the shape of the produced plasma from a sphere to a short bulging cylinder. The modified plasma ball results in increased thickness uniformity of the deposited material.
