the role of un-balanced magnetron sputtering on the characteristics of tin dioxide thin-film.
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
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.

the answer to "what is the rf sputtering technique? 5 key points to know"
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.

in this research, aluminum (al) thin films were deposited on sio2/si substrates using rf magnetron sputtering technique for analyzing the influence of rf sputtering power on microstructural surface morphologies. different sputtering rf powers (100–400 w) were employed to form al thin films. the characteristics of deposited al thin films are investigated using x-ray diffraction pattern (xrd), scanning electron microscopy (sem), atomic force microscopy (afm) and fourier-transforms infrared (ftir) spectroscopy. the x-ray diffraction (xrd) results demonstrate that the deposited films in low sputtering power have amorphous nature. by increasing the sputtering power, crystallization is observed. afm analysis results show that the rf power of 300 w is the optimum sputtering power to grow the smoothest al thin films. ftir results show that the varying rf power affect the chemical structure of the deposited films. the sem results show that by increasing the sputtering power leads to the formation of isolated texture on the surface of substrate. in conclusion, rf power has a significant impact on the properties of deposited films, particularly crystallization and shape.
