Patent ID: 8205572

Claim:
A vacuum treatment installation comprising: a vacuum receptacle ( 105 a ); a first planar metallic electrode face (EF 1 ) in the receptacle, a second dielectric electrode face (EF 2 ) facing the first planar metallic electrode face, the second dielectric electrode face forming a surface of a dielectric areal configuration ( 27 ); a metallic coupling face (KF) facing a backside (ER) of the areal configuration ( 27 ); electric connections on the coupling face (KF) and on the first electrode face (EF 1 ); a gas line system ( 17 ) through the coupling face (KF) and through an areal distributed pattern of apertures ( 29 ) in the areal dielectric configuration ( 27 ) connected to said gas line system ( 17 ) through the areal configuration ( 27 ); the areal dielectric configuration ( 27 ) comprising a plurality of mutually distant ceramic tiles ( 50 ), said areal distributed pattern of apertures through said areal dielectric configuration being formed by gaps mutually separating said ceramic tiles ( 50 ).
