ABSTRACT:
Uniform electrically conducting multicomponent material is deposited on an electrically conducting substrate by means of a PCVD method. A plasma, for example a glow discharge plasma, a high frequency plasma or a microwave plasma is generated in a reaction space. The plasma is periodically reciprocated. Starting materials for the single components of the multicomponent material are added to a flowing gas phase. To obtain multicomponent material of the desired composition, the flowing gas phase is split into at least two flowing gas phases each comprising only starting materials for a single component of the multicomponent material. The separate gas phases are time sequentially applied to the plasma. The deposited multicomponent material may be subjected to a thermal treatment.
