Abstract
The capacitive-inductive (E-H) mode transition characteristics of an ultralarge-area (2;750 × 2;350 mm2) inductively coupled plasma (ICP) system with multiple internal U-type antennas have been investigated. When the electrical characteristics of the ICP antenna such as power transfer efficiency and ICP source impedance, were measured as a function of ICP power, a distinctive change from E to H mode was identified at an rf power of approximately 3 kW. When the power transfer mode was changed from capacitive to inductive for the multiple U-type antenna configuration, better plasma uniformity was obtained owing to the more uniform power deposition along the antenna line.
