Abstract

A method is provided for fabricating a field emission device which can be adopted as the source for a flat panel display, an ultra-high frequency amplifier sensor, or an electron-beam-applied instrument. A polyimide layer is used as a release layer and a metal mask is formed thereon, thereby enabling the height of micro-tips to be easily controlled. Since the polyimide layer is soluble in an appropriate solvent, contamination does not occur during an etching process, thereby increasing the reliability of the device.
