Rf magnetron sputtering system was used to deposit ZnO:Al thin film onto corning substrates as a CO gas sensor. The dependence of doping on CO gas sensing properties was investigated. The sputtering was carried out for 30 mins under rf power of 100W. The structure of the deposited ZnO:Al films were determined by atomic force microscopy (AFM). The CO gas sensing properties were determined by in-situ measurement for surface resistance of the thin film as a function of doping and operating temperature. It was found that ZnO:Al (4 wt%) thin film exhibits high sensitivity for CO.
