  • Plasma-assisted method for thin film fabrication
    Patent number: 4798739
    Abstract: A device has a low-pressure tank placed inside an airtight chamber for plasma-depositing onto at least two substrata spaced apart in a substantial parallel relationship in the tank thin films. To effect the decomposition of the gas reagent inside the tank, at least one perforated polarized plasma generating electrode is interposed between the substrate. The airtight chamber has a pressure lower than that of the tank.
