Abstract
A method to deposit a coating including a material with highly oriented microstructure, the method including at least the following sequence of process steps: providing a flat substrate into a first vacuum processing chamber; etching one surface of the substrate by physical vapor etching; depositing a first metallic layer on the etched substrate surface by sputtering in a first metal deposition step; annealing the first metallic layer at an annealing temperature at least 50° C. higher than a compound deposition temperature of the subsequent compound deposition step; depositing a first compound layer at the compound deposition temperature on the outer surface of the first metallic layer by reactive sputtering in a first compound deposition step; and depositing a second metallic layer on the outer surface of the first compound layer by sputtering in a second metal deposition step.
