sputtering a vital and prominent process for thin film depositions. in this process, a substrate to be coated is placed in a vacuum chamber
rf sputtering provides several advantages: it works well with insulating targets the sign of the electrical field at every surface inside the plasma chamber is changing with the driving rf frequency. this avoids charge-up effects and reduces arcing. rf diode sputtering technology, recently developed works even better, because it does not need magnetic confinement and provides …

in this research, aluminum (al) thin films were deposited on sio2/si substrates using rf magnetron sputtering technique for analyzing the influence of rf sputtering power on microstructural surface morphologies. different sputtering rf powers (100–400 w) were employed to form al thin films. the characteristics of deposited al thin films are investigated using x-ray diffraction pattern (xrd), scanning electron microscopy (sem), atomic force microscopy (afm) and fourier-transforms infrared (ftir) spectroscopy. the x-ray diffraction (xrd) results demonstrate that the deposited films in low sputtering power have amorphous nature. by increasing the sputtering power, crystallization is observed. afm analysis results show that the rf power of 300 w is the optimum sputtering power to grow the smoothest al thin films. ftir results show that the varying rf power affect the chemical structure of the deposited films. the sem results show that by increasing the sputtering power leads to the formation of isolated texture on the surface of substrate. in conclusion, rf power has a significant impact on the properties of deposited films, particularly crystallization and shape.

this document presents information on dc and rf sputtering. it begins with objectives to understand sputtering, and the working of dc and rf sputtering. it then describes sputtering as a thin film coating technique where a target material is bombarded with ionized gas molecules, ejecting atoms that deposit as a thin film. dc sputtering uses a direct current power source and is a basic, inexpensive option for conductive materials. rf sputtering alternates the electric potential to prevent charge buildup on insulator targets, avoiding arcing. it provides advantages over dc sputtering for depositing insulator materials.
sputter deposition of insulating materials is achieved using power delivered at radio frequencies (rf) in angstrom systems.
