    Abstract: A plasma processing system for processing at least a substrate with plasma. The plasma processing chamber is capable of controlling ion energy distribution. The plasma processing system may include a first electrode. The plasma processing system also includes a second electrode that is different from the first electrode and is configured for bearing the substrate. The plasma processing system may also include a signal source coupled with the first electrode. The signal source may provide a non-sinusoidal signal through the first electrode to control ion energy distribution at the substrate when the substrate is processed in the plasma processing system, wherein the non-sinusoidal signal is periodic.

    Abstract: A method in a plasma processing system for etching a feature through a given layer on a semiconductor substrate. The method includes placing the substrate in a plasma processing chamber of the plasma processing system. The method also includes flowing an etchant gas mixture into the plasma processing chamber, the etchant gas mixture being configured to etch the given layer. The method additionally includes striking a plasma from the etchant source gas. Furthermore, the method includes etching the feature at least partially through the given layer while applying a bias RF signal to the substrate, the bias RF signal having a bias RF frequency of between about 45 MHz and about 75 MHz. The bias RF signal further has a bias RF power component that is configured to cause the etch feature to be etched with an etch selectivity to a second layer of the substrate that is higher than a predefined selectivity threshold.

    Abstract: A device for inductively confining capacitively coupled RF plasma formed in a plasma processing apparatus. The apparatus includes an upper electrode and a lower electrode that is adapted to support a substrate and to generate the plasma between the substrate and the upper electrode. The device includes a dielectric support ring that concentrically surrounds the upper electrode and a plurality of coil units mounted on the dielectric support ring. Each coil unit includes a ferromagnetic core positioned along a radial direction of the dielectric support ring and at least one coil wound around each ferromagnetic core. The coil units generate, upon receiving RF power from an RF power source, electric and magnetic fields that reduce the number of charged particles of the plasma diffusing away from the plasma.
