choosing between dc and rf for sputtering applications
i get this question a lot: “how do i know when to use dc and when to use rf for a sputtering application?” of course, the first thing to consider is film requirements.
advances in rf sputtering
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 …
what is rf (radio frequency) sputtering? - ulvac
in rf sputtering, high frequency alternating current is applied to a vacuum chamber and a target. it is used for metals, ceramics, silica, oxides, metal oxides, nitrides, insulators, etc. radio frequency (rf) refers to high frequencies. as it uses alternating current, the direction of particle acceleration alternates with the voltage. electrons on the chamber side flow

reactive sputtering – angstrom sciences technology - reactive sputter deposition
reactive sputtering is a variation of the sputtering or pvd deposition process in which the target material and an introduced gas into the chamber create a chemical reaction and can be controlled by pressure in the chamber.
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.

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.

a brief overview of rf sputtering deposition of boron carbon nitride (bcn) thin films - emergent materials
a great part of interest has been paid for fabricating new materials with novel mechanical, optical, and electrical properties. boron carbon nitride (bcn) ternary system was applied for variable bandgap semiconductors and systems with extreme hardness. the purpose of this literature review is to provide a brief historical overview of b4c and bn, to review recent research trends in the bcn synthesizes, and to summarize the fabrication of bcn thin films by plasma sputtering technique from b4c and bn targets in different gas atmospheres. pre-set criteria are used to discuss the processing parameters affecting bcn performance which includes the gasses flow ratio and effect of temperature. moreover, many characterization studies such as mechanical, etching, optical, photoluminescence, xps, and corrosion studies of the rf sputtered bcn thin films are also covered. we further mentioned the application of bcn thin films to enhance the electrical properties of metal-insulator-metal (mim) devices according to a previous report of prakash et al.

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.
