Abstract:
Plasma source assemblies comprising an RF hot electrode having a body and at least one return electrode spaced from the RF hot electrode to provide a gap in which a plasma can be formed. An RF feed is connected to the RF hot electrode at a distance from the inner peripheral end of the RF hot electrode that is less than or equal to about 25% of the length of the RF hot electrode. The RF hot electrode can include a leg and optional triangular portion near the leg that extends at an angle to the body of the RF hot electrode. A cladding material on one or more of the RF hot electrode and the return electrode can be variably spaced or have variable properties along the length of the plasma gap.

Claim (Index 13):
A processing chamber comprising:\n a susceptor assembly within the processing chamber, the susceptor assembly having a top surface to support and rotate a plurality of substrates around a central axis; and a gas distribution assembly having a front surface facing the top surface of the susceptor assembly to direct a flow of gases toward the top surface of the susceptor assembly, the gas distribution assembly including a plasma source assembly comprising\n a housing having an inner peripheral edge, an outer peripheral edge and a front face, the housing including a gas inlet to form a flow path from the gas inlet to allow a flow of gas to pass through the housing and out an opening in the front face, \n an RF hot electrode within the housing, the RF hot electrode having an elongate body with a first surface and a second surface, an inner peripheral end near the inner peripheral edge of the housing and an outer peripheral end near the outer peripheral edge of the housing and defining a length of the RF hot electrode, the RF hot electrode including a leg extending at an angle to the elongate body, \n a first return electrode within the housing, the return electrode having an elongate body extending between the inner peripheral edge and the outer peripheral edge of the housing, the first return electrode spaced from the first surface of the RF hot electrode to provide a first gap in which a plasma can form, \n a second return electrode within the housing, the second return electrode having an elongate body extending between the inner peripheral edge and the outer peripheral edge of the housing, the second return electrode spaced from the second surface of the RF hot electrode to provide a second gap in which a plasma can form, and \n an RF feed connected to the RF hot electrode at a distance from the inner peripheral end of the RF hot electrode that is less or equal to about 25% of the length of the RF hot electrode, \n wherein the front face of the housing of the plasma source assembly is positioned a distance from the top surface of the susceptor assembly in the range of about 1 mm to about 5 mm, and an ion flux generated at the inner peripheral end of the RF hot electrode is less than an ion flux generated at the outer peripheral end of the RF hot electrode.
