    Abstract: A method is provided for operating a processing system having a space therein arranged to receive a gas and an electromagnetic field generating portion operable to generate an electromagnetic field within the space. The method includes providing a gas into the space, and operating the electromagnetic field generating portion with a driving potential to generate an electromagnetic field within the space to transform at least a portion of the gas into plasma. The driving potential as a function of time is based on a first potential function portion and a second potential function portion. The first potential function portion comprises a first continuous periodic portion having a first amplitude and a first frequency. The second potential function portion comprises a second periodic portion having an maximum amplitude portion, and minimum amplitude portion and a duty cycle. The maximum amplitude portion is a higher amplitude than the minimum amplitude portion. The duty cycle is the ratio of a duration of the maximum amplitude portion to the sum of the duration of the maximum amplitude portion and the duration of the minimum amplitude portion. The second periodic portion additionally has a second frequency during the maximum amplitude portion. An amplitude modulation of the second periodic portion is phase locked to the first continuous periodic portion.

    Abstract: A plasma processing system that includes a plasma processing chamber that provides enhanced control over an etch process is disclosed. The plasma processing chamber is connected to a gas flow system. The gas flow system can be employed to control the release of gases into different regions within the plasma processing chamber. In addition, the volume of the released gas, e.g., the flow rate of the gas, can be adjusted by a gas flow control mechanism. In this manner, both the position and the amount of the gas that is delivered to the plasma processing chamber can be controlled. The ability to adjust the position and the amount of gas that is released into the plasma processing chamber provides for a better control over the distribution of the neutral components. This in turn enhances control over the etching process.

    Abstract: Methods for controlling bevel etch rate of a substrate during plasma processing within a processing chamber includes securing the substrate on a lower electrode within the processing chamber. A power source is provided. A gas mixture is flowed into the processing chamber. A first match arrangement coupled to an upper electrode is adjusted to control current flowing through the upper electrode to change the upper electrode from a grounded state to a floating state. A second match arrangement coupled to a top ring electrode is adjusted to control current flowing through the top ring electrode so as to control plasma formed above a top edge of the substrate. An extension of the upper electrode is lowered during plasma processing so as to minimize a gap between the extension of the upper electrode and the substrate received on the lower electrode, such that the gap is incapable of supporting plasma formed in the processing chamber.
