Abstract
To avoid arcing and shorting within a field emission device, a bottom portion of a gate electrode is protected with an insulating material to avoid or reduce arcing among the electrodes and the electron emitters in the device. In a method for manufacturing such a field emission device, an emitter hole is formed through an insulating layer such that a portion of the gate electrode overhangs the hole and is protected on its underside by the insulating layer. The device can be used in display systems, such as CNT flat panel displays.
