Reactive ion sputtering

WebSep 27, 2024 · Sputtering is a physical process in which the vaporization occurs of a solid material by bombarding it by ion energy. This is a process widely used in the formation of thin films on materials, engraving techniques, erosion of white material and analytical techniques. The sputtering is mainly caused by the momentum exchange between atoms … Webreactive sputtering, and it is necessary to consider this technique. Commonly the admission of the reactive gas in a reactive sputtering process is done by control of the flow, with a simple mechanical valve or an electronic feedback device which can indicate the magnitude of that flow.
