Abstract:
The invention relates to a device ( 1 ) and method for applying a carbon layer, in particular a diamond layer, to a substrate ( 2, 2 a ) by means of chemical vapour deposition, comprising a deposition chamber ( 3 ) into which a process gas, in particular molecular hydrogen and/or a mixture of molecular hydrogen and a carbon-containing gas, such as methane can be supplied, wherein a gas inlet and gas activation element ( 7 ) is provided in the form of a hollow body with a flow channel ( 7 b ) for the process gas, a wall ( 7 a ) surrounding the flow channel ( 7 b ), and an outlet opening ( 16 ) feeding from the flow channel ( 7 b ) into the deposition chamber ( 3 ), and a heating device ( 8 ) is provided for heating the wall ( 7 a ) of the gas inlet and gas activation element ( 7 ).

Claim (Index 24):
A method for applying a carbon layer to a substrate by chemical vapour deposition, wherein a process gas is introduced into a deposition chamber via a gas inlet and gas activation element, characterised in that a wall of the gas inlet and gas activation element is heated in such a way that the process gas flowing in the flow channel of the gas inlet and gas activation element is excited by impact excitation and thermal excitation, wherein termination bodies are attached to ends of the gas inlet and gas activation element in order to close off the flow channel, wherein a carbon-containing process gas is introduced into the deposition chamber via a further gas inlet element, wherein the carbon-containing process gas is thermally excited by flowing over the gas inlet and gas activation element.
