    • 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.

    • The present invention relates to a process for the thermal conversion of metallic precursor layers on flat substrates into semiconducting layers with a recovery of chalcogen, as well as a device for carrying out the process. The aim of the invention is to provide a rapid and readily executable process for the thermal conversion of metallic precursor layers, as well as a device suitable for carrying out the process with as small as possible primary consumption of chalcogens..This is achieved by forming an inlet-side and outlet-side gas lock (4.1, 4.2, 4.3, 4.4) for closing a furnace chamber (1) in an oxygen-tight manner, introducing one or more substrates (6) prepared with at least one metallic precursor layer into the furnace chamber (1), introducing a chalcogen vapour /carrier gas mixture (10) above the substrates (6) at a pressure close to atmospheric pressure, said mixture being distributed as uniformly as possible over the width of the substrates (6), heating the substrates (6) in the chalcogen vapour/carrier gas atmosphere (10) to a final temperature with the metallic precursor layers being transformed into semiconducting layers, removing the chalcogen vapour that has not been consumed in the reaction, cooling the substrates (6) and removing the latter from the furnace chamber (1). It is advantageous to heat the substrates (6) in a protective gas atmosphere to a temperature at which as far as possible no condensation of chalcogens can take place.

    • Zur effizienten Herstellung insbesondere von halbleitenden Chalkogenidschichten zum Einsatz in CIS-Solarzellen wird eine Reaktionsbox in den Reaktionsraum des RTP-Vakuumofens (Rapid Thermal Processing) eingeschoben. Die Qualität der herzustellenden Schicht wird über den Prozessdruck (P P ) geregelt, der in-situ über eine optische Messung der Durchbiegung einer Membran in der Reaktionsbox als Drucksensor ermittelt wird. Aufgrund der starken Temperaturschwankungen beim RTP ist diese Messung jedoch fehlerbehaftet und erst ab einer bestimmen Größe der Membran einsetzbar. Bei der Erfindung ist außerhalb des RTP-Vakuumofens (05) eine mit der Reaktionsbox (02) über ein Zuführungsrohr (11) gasdicht verbindbare separate Druckmesseinheit (08) mit einem Messraum (09) und dem Drucksensor (10), vorzugsweise ein Wärmeleitungsmanometer (15) nach Pirani, vorgesehen. Dabei wird zumindest das Zuführungsrohr (11) über eine Heizeinrichtung (12) auf einer konstanten, thermisch vom RTP entkoppelten Temperatur (T A ) unterhalb der Prozesstemperatur (T P ), aber oberhalb der Kondensationstemperatur (T K ) des Prozessgases gehalten, die sich als Messtemperatur (T M ) auf das Prozessgas bei dessen Eintritt in die Druckmesseinheit (08) übertragen hat.
