Abstract: A method (200) for monitoring process conditions in a plasma PVD process as well as a method (300) for controlling a plasma PVD process are disclosed. The methods are performed in an apparatus (1) configured therefore. In accordance with the methods, an oscillating voltage signal is applied to a target (3), arranged in the apparatus (1), by means of a radio frequency generator 15). The response from the applied oscillating voltage signal is recorded by means of a radio frequency sensor (16). Based on the recorded response, information regarding at least one plasma process condition is derived. A computer program and a computer-readable medium are also disclosed.
Abstract: The present disclosure relates to a method for chemical vapour deposition on a substrate, the method comprising a precursor step and a reactant step, wherein the precursor step comprises chemisorbing a layer of precursor molecules on the substrate (170), and wherein the reactant step comprises adding to at least part of the substrate (170) surface species able to reduce the precursor molecule, whereby at least a part of the reduced precursor molecule is deposited on the substrate (170) surface, characterized by applying by means of a voltage source (130) a positive bias to at least part of the substrate (170) surface during at least part of the reactant step, wherein the step of adding the reducing species comprises providing by means of an electron source (150) electrons as free particles, whereby during the reactant step a closed electrical circuit is formed as the free electrons are transmitted to the substrate (170) surface.

Abstract: The sputtering process according to the present disclosure comprises providing a target consisting of carbon in a sputtering apparatus, introducing a process gas essentially consisting of a neon or a gas mixture comprising at least 60% neon into said apparatus, applying a pulsed power discharge to said target in order to create a plasma of said process gas, sputtering said target by means of said plasma. The process is able to ionize a significant amount of sputtered carbon atoms.
