Patent JP-H06283093-A (JP)
Title: Electron emission element and manufacture thereof
Inventor: ISHIZAKI MAMORU
IPC: H01J1/30
Filed: 1993-03-25
Abstract: PURPOSE:To eliminate the need of such a high precision production technique as required for cone type, and prevent the occurrence of shortcircuit for ensuring higher electrical characteristics than edge type by forming a notched edge on the first electrode and macroscopically forming the electrode to be trapezoidal. CONSTITUTION:In forming an emitter electrode 1 as the first electrode at an etching process, a notched etching mask is used to form a notched shape on the electrode 1 on the basis of etching anisotropy due to the material of the electrode 1. As a result, electrical field can be concentrated on the specific portion of edges in remarkably sharpened state among the notched edges and, therefore, the electric field strength of the portion is enhanced. Also, the small threshold of voltage for emission start can be achieved, and an increase in generated current and emission brightness can also be achieved. Consequently, high electrical characteristics can be thereby ensured. The electrode 1, when macroscopically made trapezoidal, does not become like such a standing tower as in the case of cone type, and the occurrence of shortcircuit due to the fall of the electrode 1 is extremely rare, even when many electrodes are arranged on a wide substrate and dispersion is existing in the completed state thereof.
