What is the difference between downstream and direct plasma processing?
That’s a good question! Our pictures of the Atomflo show the plasma flowing out of the device. Actually, at this point the gas is no longer strictly a plasma, because practically all of the electrons and ions have been stripped away. Our products are used for downstream plasma processing. The plasma is sustained between the electrodes inside the device. What flows out is primarily neutral species, i.e., atoms, radicals and metastable molecules. These reactive neutral species are responsible for the reactions that occur on the substrate surface.
