Abstract
A deposition apparatus and methods for controlling an actuator and a heating system in a deposition apparatus are proposed. The deposition apparatus comprises a deposition chamber and at least one substrate holder movably arranged within the deposition chamber for holding substrates to be coated. The deposition apparatus shall further comprise radio equipment having at least a first radio device which is connected to the substrate holder and a second radio device which is arranged at least partially outside the deposition chamber. Between the first radio device and the second radio device a radio link is to be established at least temporarily for transferring information.

27. A method for controlling an actuator in a deposition apparatus, the deposition apparatus comprising:
-
a deposition chamber; at least one substrate holder movably arranged within the deposition chamber for holding substrates to be coated; radio equipment having at least; a first radio device which is connected to the substrate holder, and a second radio device which is arranged at least partially outside the deposition chamber; and a radio link for transferring information being established at least temporarily between the first radio device and the second radio device; said method comprising the following steps; recording at least one measured value by means of a measuring device which is connected to the substrate holder; transferring the at least one measured value via a radio link established at least temporarily between the first radio device and the second radio device; processing the at least one measured value in a data processing unit connected to the second radio device into at least one control command; and transferring the at least one control command via the radio link established at least temporarily between the second radio device and the first radio device to the actuator.
