摘要 |
<p>The present invention provides a field emission device and a method of manufacturing the same. The device comprises a plane substrate (1), a cathode electrode (2) provided on the plane substrate and formed with emission projections (3) extending generally parallel to the surface of the plane substrate, and a gate electrode (4) provided on the plane substrate for controlling the electron emission by the emission projections. The emission projections at least of the cathode electrode are formed on an insulation layer (6) on the surface of the plane substrate such that the tips of the emission projections are positioned vertically above the level of the gate electrode, which enhances the performance of the device. <IMAGE></p> |
