PLASMA TREATMENT is the modification of surface properties by the action of a plasma.
This modification can be as simple as freeing the surface from water or hydrocarbons, and can range from so-called activation with oxygen plasmas to chemical modification of the surface molecules themselves, as in plasma nitriding.
The plasmas can be generated either by simply applying a DC or AC voltage e.g. to the substrate or a simple plate antenna (glow), by external sources like microwave plasma sources or so-called inverted sputter magnetrons.
