ABSTRACT:
In accordance with the invention, a field emission device is provided with an improved pillar structure comprising multi-layer pillars. The pillars have a geometric structure that traps most secondary electrons and an exposed surface that reduces the number of secondary electrons. Processing and assembly methods permit low-cost manufacturing of high breakdown-voltage devices, including flat panel displays.
