Antenna for plasma processor and apparatus

Abstract:

An antenna includes excitation terminals responsive to an RF source to supply an RF electromagnetic field to a plasma that processes a workpiece in a vacuum chamber. The coil includes a transformer having a primary winding coupled to the excitation terminals and a multi-turn plasma excitation secondary winding connected in series with a capacitor.

Abstract(Chinese):

天线包括响应于RF源的激励端子，以将RF电磁场提供给处理真空室中的工件的等离子体。线圈包括具有耦合到激励端子的初级绕组的变压器和与电容器串联连接的多匝等离子体激发次级绕组。
