Abstract
A plasma deposition apparatus includes a first plasma source that can produce a first plasma confined in a magnetic field, which includes: a gas distribution device configured to supply a gas, a closed-loop electrode defining a center region therein and a central axis through the central region and one or more magnets that are outside an inner surface of the closed-loop electrode. The one or more magnets can produce the magnetic field in the center region. The closed-loop electrode and the one or more magnets can produce the first plasma of activated atoms, molecules, electrons, and ions from the gas. A collimator can collimate the activated atoms, molecules, electrons, and ions produced by the first plasma source and direct the ions to a substrate.
