  DC/RF Magnetron Sputtering Thin Film Deposition Techniques  1. Introduction Thin-film deposition is an essential process in modern materials science and nanotechnology. Thin films are widely used in semiconductor devices, integrated circuits, solar cells, optical coatings, gas sensors, MEMS, magnetic storage devices, and biomedical applications. Among the various Physical Vapor Deposition (PVD) techniques, Magnetron Sputtering is one of the most widely used because it provides high-quality, uniform, dense, and strongly adherent thin films . Compared with conventional sputtering, magnetron sputtering offers a higher deposition rate, lower substrate heating, and better film quality . Depending on the type of power supply used, magnetron sputtering is classified into: DC (Direct Current) Magnetron Sputtering RF (Radio Frequency) Magnetron Sputtering 2. Definition Magnetron Sputtering is a Physical Vapor Deposition (PVD) technique in which energetic ions from a plasma bombard...
