Sputtering recipes are highly specific of the apparatus used since especially RF sputtering is highly affected by the specific chamber geometry. This may lead to variations of ideal pressures/gas fluxes/powers over several orders of magnitude.

You can deposit MoOx thin film with MoO3 target in Ar atmosphere (100 sccm). Vary substrate temp. from 150-200 degree C and vary RF power from150 W to 250 W to optimize the film quality. Do not forget to rotate the substrate holder @>70RPM/Min. You can anneal the deposited film at 400 degree C to obtain low resistivity.
