The vacuum port is connected to a vacuum pump which removes gases from the interior of the chamber and maintains the chamber at a pressure below atmospheric pressure. The substrate support is easy to service or replace since it can be removed through a sidewall of the chamber. The sidewall mounted substrate support also allows a large vacuum port to be located in the endwall of the chamber thus allowing high flow to be achieved by connecting the vacuum port a large capacity vacuum pump. The chamber also includes a modular liner, a modular plasma generating source and a modular vacuum pumping arrangement, each of which can be replaced with interchangeable equipment
