Structure and fabrication of electron-emitting device having ladder-like emitter electrode |
摘要 |
An electron- emitting device utilizes an emitter electrode (12) shaped like a ladder in which a line of emitter openings (18) extend through the electrode. In fabricating the device, the emitter openings can be utilized to self-align certain edges, such as edges (38C) of a focusing system (37), to other edges, such as edges (28C) of control electrodes (28), to obtain desired lateral spacings. The self-alignment is typically achieved with the assistance of a backside photolithographic exposure operation. The ladder shape of the emitter electrode also facilitates the removal of short-circuit defects involving the electrode.
