Ti films (600 nm in thickness) were deposited by RF magnetron sputtering on p-type Si (1 0 0) wafer with 300 nm layer of SiO2. During the process the substrate rotates at 20 rpm and the temperature is maintained about 500 °C using a quartz lamp. The substrate rotation in front of quartz lamp array optimizes both temperature and thin film deposition uniformity. Target of 99.9% Ti was used as the material source. The chamber pressure was maintained at 0.5 Pa during the deposition process. Sputtering was carried with a pure gas argon flowing of 8 cm3/min. The distance between the target and the substrate was 14 cm and the sputtering power was 150 W using RF power supply. Under these conditions, the deposition rate was 2.9 nm/min and a 600 nm thick Ti film was obtained after 210 min [14] and [15].
