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

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).
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 …
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.

this page covers advantages and disadvantages of rf sputtering technique.it mentions rf sputtering advantages and rf sputtering disadvantages.
radio frequency (rf) sputtering is a type of sputtering that is ideal for target materials that have insulating qualities. like direct current (dc) sputtering, this technique involves running an energetic wave through an inert gas to create positive ions. rf sputtering needs about nine times more input voltage than dc sputtering because the creation of the radio …
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.

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.
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.
