The method includes establishing an atmospheric pressure plasma beam from an inert gas using a power of greater than about 90W, directing the plasma beam toward a surface of the flexible polymer substrate, and scanning the plasma beam across the surface of the polymer substrate to form a treated substrate surface.
Post-discharge plasma coating device for wired substrates
A post-discharge plasma coating device for a wired substrate comprising an inner tubular electrode on an inner tubular wall for receiving the substrate and a precursor moving axially in a working direction; an outer tubular electrode coaxial with, and surrounding, the inner tubular electrode. The inner and outer electrodes are configured to be supplied with an electrical power source for producing a plasma when a plasma gas is supplied between the electrodes and is thereby excited, the plasma excited gas flowing axially in the working direction and reacting with the precursor in a coating area at the end of the inner tubular wall in the direction.

Apparatus and Methods for Roll-to-Roll (R2R) Plasma Enhanced/Activated Atomic Layer Deposition (PEALD/PAALD)
Techniques are disclosed for roll-to-roll (R2R) atomic layer deposition (ALD). R2R ALD is accomplished by arranging precursor nozzles in A/B pairs while a flexible web substrate moves underneath the A/B pairs at a uniform speed. Nozzles A of the A/B pairs continuously flow a precursor A into the process volume of the R2R ALD chamber. The plasma enhanced/activated ALD (PEALD/PAALD) embodiments utilize electron cyclotron rotation (ECR)-enhanced hollow cathode plasma sources (HCPS) where nozzles B flow activated neutrals of precursor B into the process volume. As the flexible web moves in an R2R motion, nucleates from precursor A deposited on the surface of the substrate, and neutrals of precursor B undergo a self-limiting reaction to deposit a single atomically sized ALD film/layer. In this manner, multiple ALD layers may be deposited by each successive A/B pair in a single pass of the web. There is also a heat source underneath the web to further facilitate the ALD reaction, or to support thermal ALD embodiments.
METHOD AND APPARATUS FOR SPUTTER DEPOSITION

In one form, the apparatus includes a substrate guide arranged to guide a substrate along a curved path and a target portion spaced from the substrate guide and arranged to support target material. The target portion and the substrate guide define between them a deposition zone. The apparatus includes biasing element for applying electrical bias to the target material. The apparatus also includes a confining arrangement including one or more magnetic elements arranged to provide a confining magnetic field to confine plasma in the deposition zone thereby to provide for sputter deposition of target material to the web of substrate in use. The confining magnetic field having magnetic field lines arranged to, at least in the deposition zone, substantially follow a curve of the curved path so as to confine said plasma around said curve of the curved path.

Each filament of the first and second plurality of filaments includes a conductor at least partially surrounded by an insulating shell. A first RF power source supplies a first RF power to the conductor of the intra-chamber electrode assembly.
