Patents by Inventor Markus MOHNEN

Markus MOHNEN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • CVD device component provided with an individual identifier, and method for communicating information
    Patent number: 12139793
    Abstract: Information is communicated to a process control device by performing a process that includes the step of heating a component, the component having structured volumetric regions. When the component is heated, structures present in the volumetric regions radiate in the infrared spectrum, allowing the structures to be distinguished by an infrared sensor. The structures, formed by elevations or depressions, form a machine-readable identifier, which can be used as an originality identification means for the component. Since the identifier can be determined in situ during a heating process, the process control device can recognize whether correction values are to be used for the thermal treatment of a substrate.
    Type: Grant
