pvd products manufactures magnetron sputtering systems for metallic and dielectric thin film deposition on substrates up to 300 mm in diameter.
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.

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
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. (opt. lett. 41, 4249, 2016).

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.

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.
sputtering is widely used in thin film deposition as a coating method and has developed extensively to achieve required properties for different 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.
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 …

the increasing demands from micro-power applications call for the development of the electrode materials for li-ion microbatteries using thin-film technology. porous olivine-type lifepo4 (lfp) and nasicon-type li3fe2(po4)3 have been successfully fabricated by radio frequency (rf) sputtering and post-annealing treatments of lfp thin films. the microstructures of the lfp films were characterized by x-ray diffraction and scanning electron microscopy. the electrochemical performances of the lfp films were evaluated by cyclic voltammetry and galvanostatic charge-discharge measurements. the deposited and annealed thin film electrodes were tested as cathodes for li-ion microbatteries. it was found that the electrochemical performance of the deposited films depends strongly on the annealing temperature. the films annealed at 500 °c showed an operating voltage of the porous lfp film about 3.45 v vs. li/li+ with an areal capacity of 17.9 µah cm−2 µm−1 at c/5 rate after 100 cycles. porous nasicon-type li3fe2(po4)3 obtained after annealing at 700 °c delivers the most stable capacity of 22.1 µah cm−2 µm−1 over 100 cycles at c/5 rate, with an operating voltage of 2.8 v vs. li/li+. the post-annealing treatment of sputtered lfp at 700 °c showed a drastic increase in the electrochemical reactivity of the thin film cathodes vs. li+, leading to areal capacity ~9 times higher than as-deposited film (~27 vs. ~3 µah cm−2 µm−1) at c/10 rate.
