摘要:
In a method for fabricating a field emission device, a cathode electrode is first formed on a substrate and an emitter having a carbon-based material is formed on the cathode electrode. After an emitter surface treatment agent is deposited on the substrate to cover the emitter, the emitter surface treatment agent and hardened and removed from the substrate such that the carbon-based material contained in the emitter can be exposed out of a surface of the emitter.
摘要:
An electron emission device where the electron emission of the emitter at the respective pixels is uniformly controlled. The electron emission device includes first and second substrates facing each other with a distance, and gate and cathode electrodes formed on the first substrate while interposing an insulating layer. Electron emission sources are electrically connected to the respective cathode electrodes. A resistance layer is disposed between the cathode electrode and the electron emission source in substantially the same plane as the cathode electrode. At least one anode electrode is formed on the second substrate. A phosphor screen is placed on a surface of the anode electrode.

A cathode substrate for an electron emission device includes a substrate, electron emission regions formed on the substrate, and one or more driving electrodes controlling the electrons emitted from the electron emission regions. A first insulating layer contacts the driving electrodes. A focusing electrode is provided in the cathode substrate to focus the electrons emitted from the electron emission regions. A second insulating layer is located between the driving electrodes and the focusing electrode. The materials used in the first and the second insulating layers have different etch rates.

An electron emission device is disclosed. The electron emission device includes a resistance layer for electrically connecting a line electrode and isolate electrodes included in the cathode electrode. The cathode electrode can maintain a uniform voltage due to the resistance layer. A protection layer is located on the resistance layer. The protection layer prevents conductive elements contained in the resistance layer from diffusing over the protection layer. The protection layer also prevents the resistance layer from being oxidized.

A manifold absolute pressure (MAP) sensor for internal combustion engines is disclosed. In the MAP sensor, the top and bottom cases (1, 7) of a sensor housing have a plurality of fitting slots (10) and fitting protrusions (11) at their connection edges respectively and are easily and tightly assembled into a single structure through a mechanical fitting and epoxy bonding process. A plurality of support protrusions (12, 12') are internally formed on each of the top and bottom cases (1, 7) and support each side of the circuit board (5), with the circuit board (5) being positioned under the sensor member (4) and allowing the pressure inlet pipe (4') of the sensor member (4) to pass through. A supporting ring (13) and an O-ring (14) are commonly fitted over the pressure inlet pipe (4') of the sensor member (4) and are closely fitted into the enlarged top end of the pressure inlet port (8).
