Abstract
An anode plate (10) for use in a field emission flat panel display device (8) includes a transparent substrate (26) having a plurality of spaced-apart, electrically conductive regions (28) are covered by a luminescent material (24) and from the anode electrode. A getter material (29) of porous silicon is deposited on the substrate (26) between the conductive regions (28) of the anode plate (10). The getter material (29) of porous silicon is preferably electrically nonconductive, opaque, and highly porous. Included are methods of fabricating the getter material (29) on the anode plate (10).
