Abstract
Fabrication of spacer supports for use in flat panel displays through a process which involves 1) depositing an insulating material on an electrode plate, 2) optionally, patterning a reflective material superjacent the insulating material, 3) irradiating the electrode plate, and thereby removing the exposed insulating material, 4) optionally, removing the reflective material, and thereby exposing the remaining insulative material which will serve as the spacer supports, after which the plate can be aligned with a complementary electrode plate, and a vacuum formed therebetween.
