  • Patent number: 12325912
    Abstract: An apparatus deposits carbon-containing structures on a substrate conveyed through an interior space of a housing. The interior space has a central zone between a first peripheral zone and a second peripheral zone. The substrate enters the housing through a first opening of the housing, passes through the first peripheral zone, central zone, and second peripheral zone, and leaves the housing through a second opening of the housing. The second peripheral zone has a gas inlet with a gas outlet opening that feeds a carbon-containing process gas into the housing. The housing has a heating device partially disposed in the central region for thermally activating the process gas. A pump evacuates gas from the interior space through a gas outlet. Means are provided for the controlled entry of a reactive gas into the first and second peripheral zones.
