Claim Text:
1. A method for plasma-based coating of thin films on a substrate, said method comprising: placing a substrate on a support within a chamber such that a side of said substrate to be coated faces at least one electrode of a plurality of electrodes within said chamber, and a minimum gap between said one electrode and said substrate is less than a width of said one electrode, wherein said chamber is connected to a vacuum pump, a gas pressure in said chamber is maintained in a range of 50 Pascals to 2000 Pascals, said plurality of electrodes within said chamber have lengths greater than their widths or heights, and said at least one electrode has a front side opposite said support for said substrate; maintaining a part of said substrate adjacent said support at a temperature less than 200° C.; providing AC power to at least a first electrode of said plurality of electrodes to form a plasma between said first electrode and a second electrode of said plurality of electrodes, and between said first electrode and said substrate providing ion bombardment of said substrate; and injecting a first gas into a space between opposing faces of said first and second electrodes to flow towards said substrate in the plasma between said first and second electrodes so that said gas deposits a thin film on said substrate as it flows adjacent said front side of said at least one electrode without recirculation.
