发明名称 Plasma source with process nonuniformity improved using ferromagnetic cores
摘要 The present invention uses the placement of ferromagnetic cores to improve the nonuniformity of plasma processing and to increase the energy transfer efficiency of plasma sources which couple energy to a plasma through the use of radio frequency current flowing through a coil adjacent to a dielectric window. In addition, eddy current conductive elements can be used either alone or in combination with ferromagnetic cores to increase the nonuniformity adjustment range.
