Target for cathode sputtering and method of its production
Abstract:
Oxide-ceramic targets of partially reduced indium oxide-tin oxide mixtures are described. The targets provide high sputter performances, and they exhibit an essentially defined degree of reduction between 0.02 and 0.3, a density between 75 and 98% of the theoretical density and a specific electric resistance between 89.times.10.sup.-3 and 0.25.times.10.sup.-3 .OMEGA. cm. The degree of reduction must not deviate at any point on the target surface by more than 5% from the average degree of reduction of the target. The targets are produced by means of hot-pressing the oxide mixtures which were partially reduced beforehand in a special method step.
