Patent ID: 8828504

Claim:
A method comprising: providing a chamber including first and second electrodes, the second electrode including a plurality of openings; providing a substrate within the chamber beneath the first electrode and having an exposed surface facing the second electrode; providing vacuum pressure within the chamber; evaporating a solid material within the chamber to form vapor; introducing a hydrogen-containing gas into a space in the chamber between the first and second electrodes; causing the vapor to pass through the plurality of openings in the second electrode and to provide a substantially homogeneous distribution of the vapor within the space between the electrodes; generating substantially uniformly distributed plasma in the space between the first and second electrodes, and forming a thin film of hydrogenated material on the substrate while: generating the substantially uniformly distributed plasma in the space between the electrodes, causing the vapor to pass through the plurality of openings in the second electrode and into the space between the first and second electrodes, and introducing the hydrogen-containing gas into the space between the first and second electrodes.
