In the present invention a sub-stoichiometric ceramic ZnOx:Al target, with 0.3<x<1, is used for depositing a ZnO:Al layer in a reactive sputtering process. The process is carried out in an Ar / O2 atmosphere. The diagram depicts the deposition rate R depending on the oxygen flow in a sputtering process according to the present invention compared with a conventional sputter process using a stoichiometric ZnO target. The upper line x<1 indicates the deposition rate R when using the inventive target and process. The lower line x=1, for comparison only, indicates the deposition rate R when using a stoichiometric ceramic ZnO target. It can be seen from the diagram that both processes are quite stable as there are no steep slopes when varying the oxygen flow. However, the line x<1 is above the line x=1. Therefore, a working point P may be selected which has a higher deposition rate R than a corresponding working point P of a corresponding ceramic target. A higher deposition rate, however, entails a lower bombardment of the deposited layer with oxygen ions. Therefore, the quality of the ZnO:Al layer is improved as far as the conductivity and the etchability of the layer are concerned.

The invention relates to a sputter chamber for coating substrates, in which the so-called ''picture frame effect'' is eliminated or at least largely reduced. The thickness of the coating at the margin of a substrate hereby no longer deviates significantly from the thickness of the coating in the center of the substrate. This is attained thereby that the negative effect of the process gas-or of several process gases-which is introduced into the sputter chamber is equalized by an additional inert or reactive gas. At the margins of the substrates to be coated and on the substrate side facing away from the cathode thus an additional gas stream is generated, which is directed counter to the process gas stream.
