Dependence of electrical properties on technologic parameters has been studied for gas-sensitive SnO2 layers prepared by magnetron sputtering. It has been shown that it is possible to control the initial conductance and gas sensitivity of those layers. A method has been proposed to improve the reproducibility of the mentioned parameters on the level necessary for practical application of adsorbing semiconductor gas sensors based on thin SnO2 films.
