A method for coating a substrate with an AlOx layer, in particular an Al2O3 layer, comprising the following method steps: (a) providing an inductively coupled plasma source (ICP source) having a reaction chamber and at least one RF inductor, (b) introducing an aluminium compound, preferably trimethylaluminium (TMA) into the ICP source, (c) introducing oxygen and/or an oxygen compound as reactive gas into the ICP source and inductively coupling of energy into the ICP source for forming a plasma, and (d) depositing the AlOx layer on the substrate. The invention also relates to a coating assembly for depositing thin layers on a substrate, in particular for carrying out the above method. The coating assembly comprises an inductively coupled plasma source (ICP) having a reaction chamber and at least one RF inductor, a substrate holder for arranging the substrate in the reaction chamber and channels for introducing the aluminium compound and a reactive gas in the ICP source. The substrate is arranged in the reaction chamber such that the substrate surface to be coated faces the ICP source. |
