摘要： A field emission display apparatus includes a plurality of emitters formed on a substrate. Each of the emitters includes a titanium silicide nitride outer layer so that the emitters are less susceptible to degradation. A dielectric layer is formed on the substrate and the emitters, and an opening is formed in the dielectric layer surrounding each of the emitters. A conductive extraction grid is formed on the dielectric layer substantially in a plane defined by the emitters, and includes an opening surrounding each of the emitters. A cathodoluminescent faceplate having a planar surface is disposed parallel to the substrate.

摘要： An emitter substructure and methods for manufacturing the substructure are described. A substrate has a p-region formed at a surface of the substrate. A n-tank is formed such that the p-region surrounds a periphery of the n-tank. An emitter is formed on and electrically coupled to the n-tank. A dielectric layer is formed on the substrate that includes an opening surrounding the emitter. An extraction grid is formed on the dielectric layer. The extraction grid includes an opening surrounding and in close proximity to a tip of the emitter. An insulating region is formed at a lower boundary of the n-tank. The insulating region electrically isolates the emitter and the n-tank along at least a portion of the lower boundary beneath the opening. The insulating region thus functions to displace a depletion region associated with a boundary between the p-region and the n-tank from an area that can be illuminated by photons traveling through the extraction grid or openings in the extraction grid. This reduces distortion in field emission displays.

摘要： A field emission display includes a substrate, a plurality of emitters formed on the substrate, a semiconductor device formed in or on the substrate for controlling the flow of electrons to the emitters and a dielectric layer formed on the substrate. An extraction grid is formed on the dielectric layer substantially in a plane of tips of the plurality of emitters and includes openings each surrounding one of the emitters. The display also includes a transparent viewing screen, a transparent conductor formed on the viewing screen and a cathodoluminescent layer formed on the transparent conductor. The semiconductor device includes a gate dielectric and a field oxide. Significantly, the field oxide includes an interfacial region acting as a trapping and recombination site for mobile charge carriers. As a result, the semiconductor device is more robust and is better able to resist parameter shifts or performance degradation due to exposure to X-rays and photons that are incidentally generated along with the desired images on the display. This results in a more robust field emission display.
