Claim Text:
1. An arrangement for producing structured substrates with a device for applying layer systems to a substrate, the arrangement comprising: an air-tight chamber; at least one liquid supply line for supplying liquid materials to the air-tight chamber for applying the liquid materials to form a layer system; a rotating holder for substrates; and a collecting device surrounding the rotating holder and arranged in the air-tight chamber, the collecting device adapted to collect liquid materials spun off of the substrate, wherein the collecting device has at least two removal devices configured to remove the collected liquid materials selectively, individually or in batches, wherein the collecting device in the air-tight chamber surrounds the rotating holder annularly and has at least two collection zones separated from one another by separating elements formed on a common wall of the collecting device to collect the spun-off liquid materials, wherein the air-tight chamber is filled with an inert gas, wherein the separating elements are oriented diagonally relative to the common wall and are oriented diagonally relative to a surface of the rotating holder, and wherein the separating elements of the collecting device, on the side facing the rotating holder, form a plurality of ring-shaped channels, wedge-shaped in cross section, as the collection zones, the air-tight chamber being provided with the at least two removal devices, wherein each of the ring-shaped channels of the separating elements is connected to one of the removal devices via drainage channels passing laterally through the common wall.
