Method for adjusting voltage on a powered faraday shield
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 depositio...

| description | 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. |
