Abstract: A plasma source is provided including a core element extending from a first end to a second end along a first axis. The plasma source further includes one or more coils disposed around respective one or more first portions of the core element. The plasma source further includes a plasma block having one or more interior walls at least partially enclosing an annular plasma-generating volume that is disposed around a second portion of the core element. The annular plasma-generating volume includes a first region that is symmetrical about a plurality of perpendicular axes that are perpendicular to a first point positioned on the first axis, the first region having a width in a direction parallel to the first axis and a depth in a direction perpendicular from the first axis. The first region has a width that is at least three times greater than the depth of the first region.

Abstract: A remote plasma source is disclosed that includes a core element and a first plasma block including one or more surfaces at least partially enclosing an annular-shaped plasma generating region that is disposed around a first portion of the core element. The remote plasma source further comprises one or more coils disposed around respective second portions of the core element. The remote plasma source further includes an RF power source configured to drive a RF power signal onto the one or more coils that is based on a determined impedance of the plasma generating region. Energy from the RF power signal is coupled with the plasma generating region via the one or more coils and the core element.
