Abstract

A reaction chamber for carrying out substrate coating methods is disclosed, having at least one opening in at least one outer wall in which an HF feedthrough is inserted in a pressure or vacuum tight manner. The reaction chamber is further characterized by a combination of the following features: a support plate with coolant channels, and at least one opening for an HF line; an HF line collar in the zone disposed in the reaction chamber, a first seal on the collar; a first disc from an insulating material between a second seal on the support plate and the first seal on the collar; a thread in the zone outside the reaction chamber, a screw element being screwed onto the thread, all configured to prevent an electrical contact between the HF line and the support plate being established or an arc-over between the HF line and the support plate occurring.
