摘要： A substrate processing chamber comprises an electrostatic chuck comprising a ceramic puck having a substrate receiving surface and an opposing backside surface. In one version, the ceramic puck comprises a thickness of less than 7 mm. An electrode is embedded in the ceramic puck to generate an electrostatic force to hold a substrate, and heater coils in the ceramic puck allow independent control of temperatures at different heating zones of the puck. A chiller provides coolant to coolant channels in a base below the ceramic puck. A controller comprises temperature control instruction sets which set the coolant temperature in the chiller in relation prior to ramping up or down of the power levels applied to the heater.

摘要： A method of processing a workpiece in the chamber of a plasma reactor includes introducing a process gas into the chamber, simultaneously (a) capacitively coupling VHF plasma source power into a process region of the chamber that overlies the wafer, and (b) inductively coupling RF plasma source power into the process region, and controlling dissociation of species in the process region by controlling the effective frequency of the VHF source power.

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.
