Title: Electron emission element and manufacture thereof
Inventor: KIYOUGAKU MASABUMI
IPC: H01J9/02
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To improve the probability electron scattering on a conductive film to improve the electron emission efficiency by forming a film removing layer on the conductive film to form an electron emission part, and then performing the treatment for removing the film removing layer. SOLUTION: A conductive film removing layer 15 is layered on a conductive film 14. When a voltage is applied between electrodes 12 and 13 for carrying a current to the conductive film 14, the conductive film 14 is locally broken, deformed, or affected to form a minute clearance. The resulting conductive film 14 is subjected to activation treatment to form a conductive film 16 mainly composed of carbon. Thereafter, the conductive film removing layer 15 is removed by dry etching, and the conductive film 16 present on the conductive film removing layer 15 is removed by liftoff. Accordingly, the conductive film 16 is left only in the vicinity of the pole of the minute clearance of the conductive film 14, and a conductive structure 17 composed mainly of carbon is formed. The clean surface of the conductive film 14 is exposed after the removal of the conductive film removing layer 15.
