    Abstract: A method includes providing an electron gun having a first head with a thermionic electron source and an accelerating electrode, and further includes replacing the first head with a second head having a power rating substantially different than that of the first head, and subsequently operating the electron gun without replacing the accelerating electrode. The electron gun may further include a platform spaced apart from the accelerating electrode and having an adjustably located locating member that engages a reference member on the head to position the head in three dimensions relative to the accelerating electrode. The platform may be adjustably spaced from the accelerating electrode in order vary the distance between the electron source and the accelerating electrode.

    Abstract: A method and apparatus for editing an integrated circuit by bombarding a feature in need of editing with either a low-energy or high-energy electron beam in the presence of a gas whereby low energy electrons activate reactants adsorbed on the surface of the feature in need of editing to form active species on the feature surface. The reaction products from the process can be easily removed whereby IC damage, leakage between metal features, wafer contamination and physical sputtering of undesired material can be significantly minimized while still possessing nanometer-scale spatial resolution. The low energy electrons for activating the reactants adsorbed on the surface of the feature to be edited may be emitted from the electron beam itself or they may be secondary low energy electrons emitted from the surface of the feature being edited.

    Abstract: A method and apparatus for electron beam processing using an electron beam activated gas to etch or deposit material. The invention is particularly suitable for repairing defects in lithography masks. By using an electron beam in place of an ion beam, the many problems associated with ion beam mask repair, such as staining and riverbedding, are eliminated. Endpoint detection is not critical because the electron beam and gas will not etch the substrate. In one embodiment, xenon difluoride gas is activated by the electron beam to etch a tungsten, tantalum nitride, or molybdenum silicide film on a transmission or reflection mask. To prevent spontaneous etching by the etchant gas in processed sites at which the passivation layer was removed, processed sites can be re-passivated before processing additional sites.
