摘要： An apparatus and method for adjusting the voltage applied to a Faraday shield of an inductively coupled plasma etching apparatus is provided. An appropriate voltage is easily and variably applied to a Faraday shield such that sputtering of a plasma can be controlled to prevent and mitigate deposition of non-volatile reaction products that adversely affect an etching process. The appropriate voltage for a particular etching process or step is applied to the Faraday shield by simply adjusting a tuning capacitor. It is not necessary to mechanically reconfigure the etching apparatus to adjust the Faraday shield voltage.

摘要： An antenna arrangement for generating an rf field distribution at a plasma generating region inside a chamber wall of a process chamber of a plasma processing apparatus is described. The antenna arrangement includes an rf inductive antenna to which an rf power supply can be connected to supply an rf current to generate a first rf field extending into the plasma generating region. A passive antenna is also provided which is inductively coupled to the rf inductive antenna and configured to generate a second rf field modifying the first rf field. The rf field distribution at the plasma generating region increases the processing uniformity of the processing apparatus compared to that in the absence of the passive antenna.

摘要： A plasma processing system for processing a substrate which includes a single chamber, substantially azimuthally symmetric plasma processing chamber within which a plasma is both ignited and sustained for the processing. The plasma processing chamber has no separate plasma generation chamber. The plasma processing chamber has an upper end and a lower end. The plasma processing system includes a coupling window disposed at an upper end of the plasma processing chamber and an RF antenna arrangement disposed above a plane defined by the substrate when the substrate is disposed within the plasma processing chamber for the processing. The plasma processing system also includes an electromagnet arrangement disposed above the plane defined by the substrate. The electromagnet arrangement is configured so as to result in a radial variation in the controllable magnetic field within the plasma processing chamber in the region proximate the coupling window and antenna when at least one direct current is supplied to the electromagnet arrangement. The radial variation is effective to affect processing uniformity across the substrate. The plasma processing system additionally includes a dc power supply coupled to the electromagnet arrangement. The dc power supply has a controller to vary a magnitude of at least one direct current, thereby changing the radial variation in the controllable magnetic field within the plasma processing chamber in the region proximate the antenna to improve the processing uniformity across the substrate.
