WebPECVD processing allows deposition at lower temperatures, which is often critical in the manufacture of semiconductors. The lower temperatures also allow for the deposition of organic coatings, such as plasma polymers, that have been used for nanoparticle surface functionalization. [5] WebOPERATING PRINCIPLE . After the reactive gases introduction in the reactor, an electrical discharge is applied between two electrodes. Consequently, gases molecules are decomposed in the plasma that appears. The different chemical species that are created react between themselves and at the interface vapour phase/substrate. shopsmith power station shelves
