Description
Technical Field
The invention belongs to the field of microelectronic science and technology, nano science and technology, vacuum science and technology, photoelectronic science and technology, integrated circuit science and technology, and planar display technology, and relates to the manufacture of planar field emission light-emitting display, in particular to the manufacture of planar field emission light-emitting display with carbon nanotube cathode, especially to a light-emitting display with multi-interrupted oblique belt circular truncated cone cylindrical surface cathode hyperbolic laminated gate structure.
Background
Carbon nanotubes are a nanotube-like material with a high aspect ratio, and are a film material that is black from a macroscopic perspective. In a vacuum environment, the carbon nanotubes can continuously emit electrons as long as an electric field strength with strength is formed on the surfaces of the carbon nanotubes. By utilizing this property, the carbon nanotubes can be used as a cold cathode electron source for a display. In the light emitting display of the three-pole structure, the gate operating voltage of the light emitting display becomes low due to the close gate-cathode distance.
However, there are many technical problems to be solved in the field emission light emitting display of the triode structure. For example, due to the limitation of the fabrication structure, the fabrication area of the carbon nanotube layer is usually small, which reduces the number of carbon nanotube cathodes; however, the insufficient amount of carbon nanotubes for electron emission cannot provide sufficient cathode current for the light emitting display, and thus the fabrication area of the carbon nanotube layer needs to be increased as much as possible. For example, the electron emission efficiency of carbon nanotubes is very low, some carbon nanotubes can only emit a small amount of electrons under the action of strong electric field intensity, most carbon nanotubes do not emit electrons at all, and only a small amount of carbon nanotubes emit electrons to form a cathode electron source of a light-emitting display, which is far from sufficient. For example, the gate electrode has poor controllability to the carbon nanotube layer. When a larger gate voltage is applied to the gate electrode, a strong electric field intensity cannot be formed on the surface of the carbon nanotube layer, so that the carbon nanotube can emit a large amount of electrons; once the gate voltage is too high, it is also very easy to cause the occurrence of short circuit between the gate and the cathode, so that the insulating material of the light emitting display is broken down, resulting in permanent damage of the light emitting display. It is necessary to solve these technical problems from various aspects such as a manufacturing structure, a manufacturing process, a manufacturing material, and the like, thereby promoting the development of the light emitting display.
