Abstract

See full text

The targets for cathodic sputtering according to this invention are formed of hot-pressed or hot isostatic-pressed indium oxide/tin oxide powder with a minimum density of 95% of the theoretical density and with a sub-stoichiometric oxygen content are known. In order to provide the improvement of high stability and, simultaneously, high sputtering rate, it is proposed according to the invention that the target have a crystalline phase which is formed as a solid solution of indium oxide and tin oxide with a minimum of 90% by weight, preferably a minimum of 97%, of the solid solution, and which has an average grain size ranging from 2 .mu.m to 20 .mu.m. In order to make available a simple and cost-efficient method for producing a target consisting of a starting powder of indium oxide/tin oxide, which allows for a precise setting of the oxygen content and a homogeneous chemical composition throughout the entire target volume, it is proposed that a starting powder be used that is produced by oxidizing finely distributed indium tin metal.
