    Abstract: A display includes a substrate and an emitter formed on the substrate. A first dielectric layer is formed on the substrate to have a thickness slightly less than a height of the emitter above the planar surface and includes an opening formed about the emitter. The display also includes a conductive extraction grid formed on the first dielectric layer. The extraction grid includes an opening surrounding the emitter. The display further includes a second dielectric layer formed on the extraction grid and a focusing electrode formed on the second dielectric layer. The focusing electrode is electrically coupled to the emitter through an impedance element. The focusing electrode includes an opening formed above the apex. The focusing electrode provides enhanced focusing performance together with reduced circuit complexity, resulting in a superior display.

    Abstract: Diamond microtip field emitters are used in diode and triode vacuum microelectronic devices, sensors and displays. Diamond diode and triode devices having integral anode and grid structures can be fabricated. Ultra-sharp tips are formed on the emitters in a fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.
