Abstract (en)

[origin: WO8602774A1] Alteration of a precisely located site on a substrate (35) using apparatus that comprises: a) a focusable ion source (10); b) a lens (22) positioned to focus ions emitted by the source into an ion beam (124); c) a vacuum chamber (30) for containing the substrate site in the path of the ion beam; and d) a directed gas inlet (55) positioned to provide a localized supply of a substance at the site whereby the beam interacts with the substances to cause the alteration localized at the site. Methods of performing the alteration are also disclosed.
