  • Patent number: 6274972
    Abstract: An electron beam apparatus includes an electron source having an electron-emitting device, an electrode for controlling an electron beam emitted from the electron source, a target to be irradiated with an electron beam emitted from the electron source and a spacer arranged between the electron source and the electrode. The spacer has a semiconductor film on the surface thereof that is electrically connected to the electron source and the electrode.

  • Patent number: 5594296
    Abstract: An electron source or electron beam apparatus comprises an electron-emitting device and a shield member disposed above the electron-emitting device. The electron-emitting device generates an electric field component, when energized, that is parallel to a substrate surface on which the electron-emitting device is disposed, while the shield member has an aperture which allows electrons emitted from the electron-emitting device to pass therethrough, but blocks off charged particles flying toward the electron emitting device.
