The invention provides a coating system for coating substrates in a cyclic mode. The process stations of the coating system are disposed in a circular fashion. A handling mechanism is provided for transferring the substrates between the process stations. The process stations comprise a lock for loading and unloading the substrates, at least two coating chambers, each of which comprises a plasma source for stationary coating of the substrate, and preferably a heating station.
摘要:
A method of coating a substrate by magnetron cathode sputtering includes a sputtering cathode having pole shoes and being arranged in a vacuum chamber. A target and a magnetic field are provided in an area of the surface of the target and the magnetic field is varied stepwise and/or continuously to displace the plasma radially such that the erosion groove is likewise displaced radially. The variable magnetic field is generated by coils between the back surface of the target and a yoke plate while a static magnetic field is gernated by an annularly arranged magnet in the area of the yoke plate and a target space between the target and the substrate is shielded by means of an iron core which also increases the field strength of the variable magnetic field.
摘要:
An apparatus for surface coating or for lacquering a substrate, such as a disk-shaped substrate 2, which can be placed on a substrate carrier 14 and can be driven or given a rotating movement by means of a drive device, wherein the material or the lacquer fluid 5 to be applied is placed on the substrate 2 from a feed device 6. The fluid medium or the lacquer 4 released by the substrate support 14 is delivered at least to a first collecting reservoir 17 which is connected with at least one filter 28, from where the fluid is indirectly or directly conducted via a pump 29 to the first collecting reservoir 27, wherein an underpressure can be set between a first flow-off line 33 of the first collecting reservoir 27 and the pump 29.
