Method and device for controlling thickness during spin coating

The invention relates to a method and a device for regulating the thickness of coatings or layers, in particular of bond coatings, wherein bonding is controlled in a programmed manner thereby taking into account the influence of disturbance variables. The invention can be used especially in the prod...

Zusammenfassung:	The invention relates to a method and a device for regulating the thickness of coatings or layers, in particular of bond coatings, wherein bonding is controlled in a programmed manner thereby taking into account the influence of disturbance variables. The invention can be used especially in the production of DVDs. The advantages of the present invention are reproducible accuracy in adjusting the thickness of the coating/bond coating and thus an increased production output.
