the effect of rf sputtering conditions on the physical characteristics of deposited gegan thin film

ge0.07gan films were successfully made on si (100), sio2/si (100) substrates by a radio frequency reactive sputtering technique at various deposition conditions listed as a range of 100–400 °c and 90–150 w with a single ceramic target containing 7 at % dopant ge. the results showed that different rf sputtering power and heating temperature conditions affected the structural, electrical and optical properties of the sputtered ge0.07gan films. the as-deposited ge0.07gan films had an structural polycrystalline. the gegan films had a distorted structure under different growth conditions. the deposited-150 w ge0.07gan film exhibited the lowest photoenergy of 2.96 ev, the highest electron concentration of 5.50 × 1019 cm−3, a carrier conductivity of 35.2 s∙cm−1 and mobility of 4 cm2·v−1∙s−1.

radio frequency magnetron sputter deposition as a tool for surface modification of medical implants

the resent advances in radio frequency (rf)‐magnetron sputtering of hydroxyapatite films are reviewed and challenges posed. the principles underlying rf‐magnetron sputtering used to prepare calcium phosphate‐based, mainly hydroxyapatite coatings, are discussed in this chapter. the fundamental characteristic of the rf‐magnetron 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.

dc&rf sputtering | pdf | sputtering | thin film

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.

magnetron sputtering technique for analyzing the influence of rf sputtering power on microstructural surface morphology of aluminum thin films deposited on sio2/si substrates - applied physics a

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.

investigation of the rf sputtering process and the properties of deposited silicon oxynitride layers under varying reactive gas conditions

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 1.48–1.89 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

a coating process utilizing plasma sputtering generally means to eject atoms from a solid-state target by “bombarding” it with accelerated gas ions. this technique is often used for the deposition of thin films. 

therefore a gas discharge is ignited in an inert gas (i.e. argon). the positive gas ions are accelerated towards a negative charged target …
