Apparatus for thin-coating processes for the treatment of substrates (8) of large surface area using a plasma (6) which is excited by microwaves (M) and the latter are coupled from a source by means of a waveguide (1) consisting of at least one hollow conductor (1), as well as by means of a horn antenna, into a plasma chamber (5), the waveguide (W) having a substantially rectangular aperture, an area is provided at the end of the hollow conductor (Q) with a slit-like constriction (Q), a rectangular horn (2) adjoins this area, and a compensation area (3) is provided between the largest aperture of the rectangular horn (2), as well as of the plasma chamber (5).

Apparatus for thin-coating processes for treating substrates of great

A heated evaporator housing is provided at its inlet with an ultrasonic atomizer for reducing monomer to small droplets and a permeable porous body completely occupying a cross section of the housing between the inlet and the outlet. A vacuum pump and a reaction chamber for coating substrates are provided downstream of the outlet.
