WebA plasma enhanced chemical vapour deposition (PECVD) system with parallel plate electrodes was used. The reactant gases used were titanium-tetrachloride or titanium-tetra-isopropoxide (TTIP) (Ti [OCH (CH 3) 2] 4) as the precursors; O 2 and argon were used as carrier gases for stability of the TiCl 4 or TTIP gas supply. WebDec 17, 2008 · Chemical Vapour Deposition (CVD) involves the deposition of thin solid films from chemical precursors in the vapour phase, and encompasses a variety of deposition techniques, including a range of thermal processes, plasma enhanced CVD (PECVD), photon- initiated CVD, and atomic layer deposition (ALD).
