the resent advances in radio frequency (rf)âmagnetron sputtering of hydroxyapatite films are reviewed and challenges posed. the principles underlying rfâmagnetron sputtering used to prepare calcium phosphateâbased, mainly hydroxyapatite coatings, are discussed in this chapter. the fundamental characteristic of the rfâmagnetron sputtering is an energy input into the growing film. in order to tailor the film properties, one has to adjust the energy input into the substrate depending on the desired film properties. the effect of different deposition control parameters, such as deposition time, substrate temperature, and substrate biasing on the hydroxyapatite (ha) film properties is discussed.
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 âŚ

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.

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 (100â400 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.

in a single process run, an amorphous silicon oxynitride layer was grown, which includes the entire transition from oxide to nitride. the variation of the optical properties and the thickness of the layer was characterized by spectroscopic ellipsometry (se) measurements, while the elemental composition was investigated by energy dispersive spectroscopy (eds). it was revealed that the refractive index of the layer at 632.8 nm is tunable in the 1.48â1.89 range by varying the oxygen partial pressure in the chamber. from the data of the composition of the layer, the typical physical parameters of the process were determined by applying the berg model valid for reactive sputtering. in our modelling, a new approach was introduced, where the metallic si target sputtered with a uniform nitrogen and variable oxygen gas flow was considered as an oxygen gas-sputtered sin target. the layer growth method used in the present work and the revealed correlations between sputtering parameters, layer composition and refractive index, enable both the achievement of the desired optical properties of silicon oxynitride layers and the production of thin films with gradient refractive index for technology applications.
sputtering is a method of thin film deposition, which is a type of pvd (physical vapor deposition). in this process, a substrate to be coated with thin film (glass substrate, si-wafer, etc.) and target (material for the thin film) are placed into a vacuum chamber, that becomes filled with an inert gas (generally, argon). when high
