    摘要： A plasma reactor for processing a workpiece includes a reactor chamber and a workpiece support within the chamber, the chamber having a ceiling facing the workpiece support, a capacitively coupled plasma source power applicator comprising a source power electrode at one of: (a) the ceiling (b) the workpiece support, and plural VHF power generators of different fixed frequencies coupled to the capacitively coupled source power applicator, and a controller for independently controlling the power output levels of the plural VHF generators so as to control an effective VHF frequency applied to the source power electrode. In a preferred embodiment, the reactor further includes a plasma bias power applicator that includes a bias power electrode in the workpiece support and one or more RF bias power generators of different frequencies coupled to the plasma bias power applicator.

    摘要： 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 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.

    摘要： 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.
