Compared to CVD, the deposition temperature of PECVD can be decreased because of the plasma energy. Lee et al. [6] investigated the deposition of TiO 2 on the silica wafer by using titanium tetraisopropoxide (TTIP) as the precursor in PECVD. The result indicated that TiO 2 films became rougher if the deposition time was increased. chipboard scrapbook ideasWebA 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. granthams art discountWebJan 27, 2024 · A substrate to be coated is placed into the deposition chamber and either heated or exposed to a plasma.
