  • Patent number: 8999187
    Abstract: A method for manufacturing a device on a substrate includes forming a layer structure on the substrate, forming an auxiliary layer on the layer structure, forming a planarization layer on the auxiliary layer and on the substrate, exposing the auxiliary layer by a chemical mechanical polishing process and removing at least partly the auxiliary layer to form a planar surface of the remaining auxiliary layer or of the layer structure and the planarization layer. The chemical mechanical polishing process has a first removal rate with respect to the planarization layer and a second removal rate with respect to the auxiliary layer and the first removal rate is greater than the second removal rate.

  • Patent number: 4649855
    Abstract: A device for coating formed bodies, like dragees, has a device for spraying the formed the formed bodies with a drageeing suspension and a suction device for sucking off air and dust while the formed bodies are in a kettle and moved therein by rotation of the kettle about a titled axis so that the drageeing material undergoes a three-dimensional rolling movement. The suction device has one or more perforated separating walls so in the kettle that, during the rotation of the kettle, running off drageeing material flows over a portion of one side thereof and air removal from the other side of the separating walls is restricted thereto. As a result, a large part of the air flows through the running off material for more effective drying and dust removal.
