Abstract: An electrode is exposed to a plasma generation volume and is defined to transmit radiofrequency power to the plasma generation volume, and includes an upper surface for holding a substrate in exposure to the plasma generation volume. A gas distribution unit is disposed above the plasma generation volume and in a substantially parallel orientation to the electrode. The gas distribution unit includes an arrangement of gas supply ports for directing an input flow of a plasma process gas into the plasma generation volume in a direction substantially perpendicular to the upper surface of the electrode. The gas distribution unit also includes an arrangement of through-holes that each extend through the gas distribution unit to fluidly connect the plasma generation volume to an exhaust region. Each of the through-holes directs an exhaust flow from the plasma generation volume in a direction substantially perpendicular to the upper surface of the electrode.

Abstract: A semiconductor wafer processing apparatus includes a first electrode exposed to a first plasma generation volume, a second electrode exposed to a second plasma generation volume, and a gas distribution unit disposed between the first and second plasma generation volumes. The first electrode is defined to transmit radio frequency (RF) power to the first plasma generation volume, and distribute a first plasma process gas to the first plasma generation volume. The second electrode is defined to transmit RF power to the second plasma generation volume, and hold a substrate in exposure to the second plasma generation volume. The gas distribution unit includes an arrangement of through-holes defined to fluidly connect the first plasma generation volume to the second plasma generation volume. The gas distribution unit also includes an arrangement of gas supply ports defined to distribute a second plasma process gas to the second plasma generation volume.
