Characteristics Analysis and Manufacture of Ta2O5 Thin Films Prepared by Dual Ion-beam Sputtering Deposition with Change of Ar/O2Gas Flow Rate of Assist Ion Beam
The Ta$_2$O$_{5}$ thin film was deposited on Si-(III) and glass substrate with the change of Ar:O$_2$ gas flow rate in the assist ion gun by the Dual ion-Beam Sputtering (DIBS). As the $O_2$ gas flow of the assist ion gun was decreased, the deposition rate of the thin films decreased. The refractive index was fixed (2.11, at 1550 nm) without regarding to $O_2$ gas flow of the range 3∼12 sccm in assist ion gun. The condition of Ar:O$_2$=3:12 was formatted stoichiometry composition of Ta$_2$O$_{5}$ and the ms roughness was small (0.183 nm).nm).
Key words: $Ta_2$$O_{5}$, Dual ion beam sputtering, Refractive index, $Ar:O_2$, Roughness
