Process and apparatus for coating of large area of substrates under atmospheric pressure

摘要

Coating substrates under atmospheric pressure conditions comprises passing a first gas stream (10) into a plasma source (1), driving off the plasma from a large volume plasma from the plasma source, directing the plasma through a nozzle (3) onto the substrate (4), and aligning the layer formation on the surface of the substrate by a physical-chemical reaction of a precursor as component of a second gas stream (6). The physical-chemical reaction is carried out directly on the surface of the substrate by adjusting the volume stream, flow speed and/or flow direction of the plasma (12) and gas stream and the distance of the nozzles for the plasma and adjusting the inner pressure in the reaction chamber (5). An Independent claim is also included for a device for carrying out the above process.
