The RIE etcher Plasmalab 80 Plus (produced by Oxford Instruments Plasma Technology, UK) is a 13.56 MHz driven parallel plate reactor with manual sample loading and a graphite substrate electrode. It is highly recommended for processing of small and non-standard substrates with Si, SiO2 and Si3N4 films.
