We have deposited microcrystalline, gc-Si, silicon films by using RF reactive magnetron sputtering (RMS) at high substrate temperatures, Ts > 500°C, and at a relatively low partial pressure of hydrogen, PH = 0.40 mTorr, and at low Ts ∼200- 300°C, but with a higher PH > 2 mTorr. We have detected μc-crystallinity by Raman scattering and transmission electron microscopy. We discuss differences in the growth mechanisms for formation of μc-Si under these two deposition conditions.
