Abstract: Techniques for fabricating carbon nanotubes aligned on a tip are provided. In one embodiment, a method for fabricating carbon nanotubes aligned on a tip includes forming nanostructures on the tip, and aligning the nanostructures on the tip using a fluid flowing on the tip.

Abstract: Field emission devices (FEDs) are provided. In one embodiment, an FED includes an electron emitter, a tube spaced apart from the electron emitter and having a first opening and a second opening, and a gate electrode disposed on an outer surface of the tube. The first opening is disposed at one end of the tube adjacent to the electron emitter, and the second opening is disposed at the other end of the tube. The FED further includes an anode that is spaced apart from the second opening and collects secondary electrons emitted from the second opening.

Abstract: Provided are a cooling device coated with carbon nanotubes and method of manufacturing the same. Carbon nanotubes are dispersively coated on a surface of the cooling device that radiates generated by a predetermined apparatus or component through thermal exchange. Thus, a carbon nanotube structure is formed so that the cooling device can improve in a thermal radiation characteristic and become small-sized. As a result, electronic devices can be downscaled and heat generated by a highly integrated electronic circuit chip can be effectively radiated, thus increasing lifetime and performance of an operating circuit.

Abstract: Provided are a method of packaging an MEMS device in vacuum using an O-ring and a vacuum-packaged MEMS device manufactured by the same. The method includes preparing an upper substrate including a cavity and a lower substrate including the MEMS device and loading the upper and lower substrates into a vacuum chamber; aligning the lower and upper substrates by mounting an O-ring on a marginal portion of the MEMS device of the lower substrate; compressing the O-ring between the upper and lower substrates by applying a pressure between the upper and lower substrates; venting the vacuum chamber; and removing the pressure applied between the upper and lower substrates. In this method, the MEMS device can be packaged in vacuum using a simple process without causing outgassing and leakage from a cavity of the upper substrate.
