Abstract: Structures and methods to ease electron emission and limit outgassing so as to inhibit degradation to the electron beam of a field emitter device are described. In one method to ease such electron emission, a layer of low relative dielectric constant material is formed under the surface of the field emitter tip. Another method is to coat the field emitter tip with a low relative dielectric constant substance or compound to form a layer and then cover that layer with a thin layer of the material of the field emitter tip.

Abstract: An FED and a method of manufacture are provided. The FED includes a cathode assembly containing an improved column line structure. The column line structure includes a conductive structure formed on a substrate. A resistive layer is formed on the conductive structure, and an insulator layer is formed partly over the resistive layer. The contact between the base of the emitter tips and the addressing column line is achieved through a lateral side that is not covered by the insulator layer. The insulator layer helps reduce the possibility of electrical shorting between the addressing column line and the row line structure of the cathode assembly. The insulator layer on top of the addressing column line will allow the use of a thinner subsequent dielectric layer. This thinner dielectric layer, which supports the grid, will provide a lower RC time constant and help achieve better video rate operation. The thinner dielectric layer also will result in smaller grid openings above the tips. This will provide for better beam spots, and, therefore, better image resolution. The thinner dielectric layer will require less applied voltage to extract electrons from the tips, resulting in lower power consumption for the FED.

Abstract: An object of the present invention is to provide a cold-cathode electron source successfully achieving a high frequency and a high output, a microwave tube using it, and a production method thereof. In a cold-cathode electron source according to the present invention, emitters have a tip portion tapered at an aspect ratio R of not less than 4, and thus the capacitance between the emitters and a gate electrode is decreased by a degree of declination from the gate electrode. For this reason, the cold-cathode electron source is able to support an operation at a high frequency. A cathode material of the cold-cathode electron source is none of the conventional cathode materials such as tungsten and silicon, but is a diamond with a high melting point and a high thermal conductivity. For this reason, the emitters are unlikely to melt even at a high current density of an electric current flowing in the emitters, and thus the cold-cathode electron source is able to support an operation at a high output.
