Rf sputtering diagram. Sputter deposition is a physical vapor deposition (PVD) method of thin film deposition by sputteringThis involves ejecting material from a "target" that is a source onto a "substrate" such as a silicon wafer Resputtering is reemission of the deposited material during the deposition process by ion or atom bombardment Sputtered atoms ejected from the target have a wide energy distribution.
