    Abstract: An inductively-coupled plasma processing chamber has a chamber with a ceiling. A first and second antenna are placed adjacent to the ceiling. The first antenna is concentric to the second antenna. A plasma source power supply is coupled to the first and second antenna. The plasma source power supply generates a first RF power to the first antenna, and a second RF power to the second antenna. A substrate support disposed within the chamber. The size of the first antenna and a distance between the substrate support are such that the etch rate of the substrate on the substrate support is substantially uniform.

    Abstract: A method of processing a workpiece in the chamber of a plasma reactor includes introducing a process gas into the chamber, capacitively coupling VHF plasma source power into a process region of the chamber that overlies the wafer while inductively coupling RF plasma source power into the process region. A particular plasma ion density level is established by maintaining the total amount of plasma source power inductively and capacitively coupled into the chamber at a level that provides the desired plasma ion density. Chemical species distribution or content in the process region plasma is controlled by adjusting the ratio between the amounts of the capacitively coupled power and the inductively coupled power while continuing to maintain the level of total plasma source power. The method further includes applying independently adjustable LF bias power and HF bias power to the workpiece and adjusting the average value and population distribution of ion energy at the surface of the workpiece by adjusting the proportion between the LF and HF bias powers.

A particular plasma ion density level is established by maintaining the total amount of plasma source power inductively and capacitively coupled into the process region at a level that provides the desired plasma ion density. The plasma ion density radial distribution in the process region is controlled by adjusting the ratio between the amounts of the (VHF) capacitively coupled power and the inductively coupled power while continuing to maintain the level of total plasma source power. The method can also include applying independently adjustable LF bias power and HF bias power to the workpiece and adjusting the average value and population distribution of ion energy at the surface of the workpiece by adjusting the proportion between the LF and HF bias powers. The VHF capacitively coupled power may be applied from the ceiling or from the wafer support.
