WebSputtering is a technique used to deposit thin films of a material onto a surface (a.k.a. "substrate"). By first creating a gaseous plasma and then accelerating the ions from this plasma into some source material (a.k.a. "target"), the source material is eroded by the arriving ions via energy transfer and is ejected in the form of neutral ...
