Abstract:
An electron amplifier and a method of manufacturing the same are provided. The electron amplifier includes a substrate in which a plurality of through holes are formed, a resistive layer deposited on the sidewalls of the through holes, an electron emissive layer including carbon nanotubes which is deposited on the resistive layer, and an electrode layer formed on each of the upper and lower sides of the substrate. Because the electron emissive layer of the electron amplifier is uniform and provides a high electron emission efficiency, the electron amplification efficiency is improved. The electron amplifier manufacturing method enables economical mass production of electron amplifiers.

Abstract:
A mobile device and a method support a touch semi-lock state. When entering into the touch semi-lock state, a predefined hot menu including items and a touch-lock icon are provided on a touch screen. An output area of the touch-lock icon on the touch screen is defined as a touch event allowable region. A specific item of the hot menu is selected in response to a user input that moves the touch-lock icon onto the specific item. A particular end-user function corresponding to the selected item is activated.
