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. (opt. lett. 41, 4249, 2016).
what is sputtering? - ulvac
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
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.

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.

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 …
