NumberTitleIssue Date
5607542Inductively enhanced reactive ion etching
A method and apparatus for generating a medium density plasma in a reactive ion etching chamber. A conventional reactive ion etching technique, using multiple electrodes for capacitive coupling of power into the chamber to establish and sustain a plasma, ...

5605637Adjustable dc bias control in a plasma reactor
A plasma chamber, and a related method for its use, in which the direct current (dc) bias on a wafer-supporting cathode is reduced by including a plasma shield that blocks plasma from reaching a region of the chamber and thereby reduces the effective surf...
