VIRTUAL SHUTTER IN ION BEAM SYSTEM
The present disclosure provides a method of processing a substrate within an ion beam system. The substrate has a top surface that has a plurality of features, an edge and a bottom surface. The substrate is placed on a wafer stage and an energetic particle beam having a radial flux distribution over at least a portion of a major dimension thereof is ignited. The energetic particle beam is stabilized while the bottom surface of the substrate is oriented toward the major dimension of the energetic particle beam. The wafer stage with the substrate is oriented so that the top surface of the substrate is exposed to the major dimension of the energetic particle beam. After stabilization of the energetic particle beam, the plurality of features on the top surface of the substrate are exposed to the energetic particle beam in a treatment zone.
Plasma-Based Process for Production of F and HF from Benign Precursors and Use of the Same in Room-Temperature Plasma Processing
Methods and apparatuses for the production of HF in an electron-beam generated plasma. A gas containing fluorine, hydrogen, and an inert gas such as argon, e.g., Ar/SF.sub.6/H.sub.2O or Ar/SF.sub.6/NH.sub.3 flows into a plasma treatment chamber to produce a low pressure gas in the chamber. An electron beam directed into the gas forms a plasma from the gas, with energy from the electron beam dissociating the F-containing molecules, which react with H-containing gas to produce HF in the plasma. Although the concentration of the gas phase HF in the plasma is a very small fraction of the total gas in the chamber, due to its highly reactive nature, the low concentration of HF produced by the method of the present invention is enough to modify the surfaces of materials, performing the same function as aqueous HF solutions to remove oxygen from an exposed material.
