METHOD AND DEVICE FOR COATING PLANAR SUBSTRATES WITH CHALCOGENS

摘要

The invention relates to a method and a device for coating planar substrates with chalcogens in the form of thin layers. The invention is intended to provide a fast and cost-effective coating of planar substrates with chalcogens, with a controlled and safe removal of the uncondensed chalcogen and a device suitable for carrying out the method. This is achieved by forming an inlet side and outlet side gas lock (6, 7) for the oxygen-tight closure of a process chamber (5), introducing one or more substrates to be coated, said substrates being temperature-regulated to a predetermined temperature, into the process chamber (5), introducing a chalcogen vapour/carrier gas mixture into the process chamber (5) which has a transport channel (4), above the substrates, forming a flow of the chalcogen vapour/carrier gas mixture through the transport channel (4) between the inlet side and outlet side gas locks (6, 7) and forming a chalcogen layer on the substrates by means of PVD during a predetermined dwell time and removing the chalcogen vapour which has not condensed onto the substrates together with the carrier gas between the gas locks, and removal of the substrates after the predetermined process time has elapsed.
