Abstract
A method of forming an electron emitter structure for use in a field emission display, or as a field emission backlight for an LCD display is provided. The electron emitter structure is formed by depositing mask elements onto an laminar Al substrate, and etching the Al substrate chemically through gaps between the mask elements, such that a spikes are formed on the substrate. These spikes are then covered with an electron emitter material. The spikes can be formed with a desired pitch/height ratio.
