Abstract:
A system for use in the fabrication of a gate structure, the apparatus comprising:a vacuum chamber including substrate assembly holder adapted to hold a substrate assembly having a surface; an ozonizer apparatus, the ozonizer apparatus comprising: an ozone source, and an ozonizer structure proximate the surface of the substrate assembly in the vacuum chamber, the ozonizer structure having openings adapted to direct ozone towards the surface of the substrate assembly; an evaporation apparatus, the evaporation apparatus comprising: a metal oxide source, and an electron beam generation device operable to generate an electron beam that impinges on the metal oxide source to evaporate metal oxide of the metal oxide source for formation of metal oxide on the surface of the substrate assembly; and an ion beam apparatus, the ion beam apparatus comprising: an inert gas source operable to provide an inert gas, and an ion gun operable to generate an ion beam using the inert gas and directing the ion beam for contact at the surface of the substrate assembly.
