They are followed, viewed in the direction of transport, to ⁇ least one, usually a plurality of successive process chambers on, depending on réelleiumderberichtdem layer or layer system. Afterwards, a gang side transfer chamber arranged.
- process chambers are generally known as function chambers or so-called compartments.
- compartments along the transport path Be istungskompart- alternate often ments, that process chambers in which the substrates are laminated be ⁇ , and pump compartments, ieificatkam ⁇ chambers serving the evacuation of individual Be Anlagenungskompart- ment or the gas separation between Be Bertungskompart- ments decreases.
- further process chambers may also be arranged to carry out further process steps, such as for temperature control or temperature treatment, for purification, passivation or activation of a substrate surface or otherwise. Also, the order of successive compartments may change.
- the individual compartments are interconnected by openings through which the substrate is passed from one compartment to the next.
- the lock chambers and the buffer chambers are vacuum-technically separable from the surrounding atmosphere or from an adjacent chamber, depending on the position in the succession of chambers, by vacuum-sealable system or intermediate gates, respectively at the entrance and the exit of the respective chamber.
- the gates are used for the discontinuous introduction or removal of substrates from the atmospheric pressure in the vacuum of the system or vice versa.
- a coarse or fine vacuum is produced after receiving the substrate and closing the system door.
- the process is carried out analogously in the reverse order.
- transfer chamber In an intermediate gate, which separates a buffer chamber to the process area, in continuous coating systems, a plant section connects, a so-called transfer chamber, in which an adaptation of the Transport regime of discontinuous sluice for continuous coating operation takes place.
- transfer chambers each have a transport device comprising sections with separate drives, a so-called Passing Band, in order to adapt the Transportgeschwin ⁇ speed of the feed rate in the front part of the transfer chamber to the process speed during the coating.

- a five-chamber system is used as a three-chamber system, which increase the lock times and consequently the cycle times of the vacuum coating system.
- the pressure is decoupled by means of flow resistance, ie by means of a gas exchange between the two chambers reducing device within the lock system, ie within the buffer ⁇ chamber or within the lock chamber or in ⁇ the chambers.
- a flow resistance reduces the open cross-section to the transported through the plant to sub- strat such that depending on the pressure ratio ⁇ sen difficult in the adjacent chamber portions, a gas exchange, and thus a pressure compensation is prevented.
- different high pressure differences can be generated with one or more graduations of the pressure within a lock system.
- Such flow resistance causes a pressure difference is generated inside the lock system with an open Eisentor ver ⁇ -bound volumes of lock and buffer chamber between the volume of the region of the lock chamber and the Volumenbe ⁇ reaching the buffer chamber.
- This pressure difference should be designed such that in the evacuated state and with an open intermediate gate between lock and buffer chamber, the pressure conditions between the surrounding atmosphere, the lock chamber, the buffer ⁇ chamber and the process area are comparable to the pressure ratios described above for separate lock and buffer chambers ,
- the components which form a flow resistance such as e.g. Parallel to the substrate arranged baffles, z. B. be supplemented in existing plants and can also remain in the plant during normal operation of the vacuum coating systems with substrate lengths that do not require an extended lock chamber.
- Sluice system can be done due to the Druckdif ⁇ ference between these two areas using the existing pumping systems.
