  • Barrier layer system and method for producing a barrier layer system
    Patent number: 12385134
    Abstract: A layer system includes barrier properties against oxygen and water vapor. There may be an alternating layer system of at least two aluminum oxide layers and at least two titanium oxide layers. The aluminum oxide layers and the titanium oxide layers are deposited alternately on top of one another. The aluminum oxide layers and the titanium oxide layers are deposited by ALD layer deposition with a layer thickness of 5 nm to 20 nm. A first Parylene layer is deposited with a layer thickness of 0.1 ?m to 50 ?m on a first side of the alternating layer system by CVD.
    Type: Grant

  • Apparatus for coating a strip-shaped substrate with a Parylene layer
    Publication number: 20250041895
    Abstract: An apparatus is provided for coating a strip-shaped substrate with a parylene layer within a working chamber, comprising a take-off roller for unwinding the strip-shaped substrate; a take-up roller for winding the strip-shaped substrate after the coating process; a processing roller, with which the strip-shaped substrate can be led past a coating zone; a first housing, which delimits the coating zone; a second housing delimiting the first housing, as a result of which the second housing delimits a volume between the first housing and the second housing; at least one inlet which extends through a wall of the first housing and by means of which at least one monomer-containing gas for depositing the parylene layer can be introduced into the coating zone; and at least one pumping means, by means of which a negative pressure can be generated in the volume between the first housing and the second housing.
