enabling technology for a better world
angstrom science’s sputtering power supply is offered in many types of sputtering power including pulsed sputtering, rf sputtering and dc.
sputtering technique uses pulsed high voltage direct current to the object to be plated and a radio frequency sputtered film source. resultant film has excellent adhesion, and objects can be plated uniformly on all sides.
sputtering is a physical process applied in several industries nowadays. here, you'll understand its procedure and applications in thin-film manufacturing.
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.

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

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 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 …

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 …
sputtering is a low pressure physical vapor deposition process where ions are accelerated from a plasma across a potential drop to bombard the sputtering
magnetron sputtering is a technology where a gaseous plasma is generated and confined to a space containing the deposition material.
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.

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).
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.
