Abstract
A device for depositing a layer on a substrate includes a process chamber and a gas inlet element. The substrate is moved in a movement direction in the process chamber during a coating process. The gas inlet element has a first, second and third gas distribution chamber with a first, second and third gas outlet zone, respectively. The second gas outlet zone is arranged immediately before the first gas outlet zone in the movement direction of the substrate and the third gas outlet zone is arranged immediately after the first gas outlet zone in the movement direction of the substrate. The first, second and the third gas distribution chambers each have a gas-heating apparatus. The first gas distribution chamber has an evaporating apparatus for a solid or liquid starting material, which can be fed into the first gas distribution chamber through an feed-in opening.
