Abstract: A method and apparatus are provided for plasma-based processing of a substrate based on a plasma source having a first, second and third electrodes disposed above a pedestal. The second electrode is disposed between the first and third electrodes. A first gap is formed between the first electrode and the pedestal and between the third electrode and the pedestal. A second gap is formed between the first and second electrodes, and a third gap is formed between the second and third electrodes. A first radio frequency (RF) power supply is connected to the first and third electrodes and is configured to predominantly deliver power to plasmas located in the first gap. A second RF power supply is connected to the second electrode and is configured to predominantly deliver power to plasmas located in the second and third gaps.

Abstract: A method and apparatus are provided for plasma-based processing of a substrate based on a plasma source having at least two adjacent electrodes positioned with the long dimensions parallel to define a first minimum gap between the two electrodes of from 5 millimeters to 40 millimeters. A second minimum gap is defined between the two electrodes and the substrate. AC power is provided to the two electrodes through separate electrical circuits from a common supply with a phase difference therebetween. A first gas and a second gas are injected into the plasma-containing volume between the two electrodes at different positions relative to the substrate. A lower electrode with a lower electrode width that is less than the combined width of the two electrodes is powered from a separately controllable AC power supply at an AC frequency different from that supplied to the two electrodes.

Abstract: A method is disclosed for forming leak-free coatings on polymeric or other surfaces that provide optical functions or protect underlying layers from exposure to oxygen and water vapor and do not crack or peel in outdoor environments. This method may include both cleaning and surface modification steps preceding coating. The combined method greatly reduces defects in any barrier layer and provides weatherability of coatings. Specific commercial applications that benefit from this include manufacturing of photovoltaic devices or organic light emitting diode (OLED) devices including lighting and displays.

Abstract: A system and method for two-sided etch of a semiconductor substrate. Reactive species are generated and flowed toward a substrate for processing. A diverter is positioned between the generation chamber and the substrate. A portion of the reactive species flows through the diverter for processing the front of the substrate. Another portion is diverted around the substrate to the backside for processing. A flow restricter is placed between the substrate and the exhaust system to increase the residence time of reactive species adjacent to the backside.
