Field emission device (FED) having cathode aperture to improve electron beam focus and its method of manufacture |
摘要 |
A Field Emission Device (FED) and its method of manufacture includes: forming a substrate; forming a cathode having a cathode aperture on an upper surface of the substrate; forming a material layer having a first through hole with a smaller diameter than that of the cathode aperture on an upper surface of the cathode; forming a first insulator having a first cavity on an upper surface of the material layer; forming a gate electrode having a second through hole on an upper surface of the first insulator; and forming an emitter in a central portion of the cathode aperture.
