In this work, we present hard-hydrogenated amorphous carbon films at high deposition rate. The films were prepared on the cathode electrode of a conventional r.f. sputtering system. Hydrogenated amorphous carbon films with excellent properties, i.e, high hardness (15 GPa), relatively low stress (~ 1.3 GPa) and with a very high deposition rate (~0.7 nm/s) were obtained at the conditions of high bias (−800 V) and high methane gas pressure (0.12 × 10 −1 mbar). The low band gap and the high I D /I G Raman ratio indicate that the films have high amount of sp 2 sites.
