MARORA - Single Wafer Plasma Nitridation / Oxidation System

MARORA provides best solutions for gate dielectric film formation for next generation advanced logic and memory devices. This tool uses a unique "modified magnetron typed (MMT)" plasma source. MMT technology provides high density plasma and low electron temperature (<1eV) which makes very uniform nitridation process possible without damaging substrates.
