Abstract:
A method of fabricating a flat panel evacuated display, comprising:forming two or more discrete blocks of an oxidizable material over a face plate substrate;forming a sacrificial material over the oxidizable material blocks and over at least one region of the substrate between the blocks, the sacrificial material being selectively removable relative to the oxidizable material;removing the sacrificial material from over the blocks while leaving some sacrificial material remaining over the at least one region between the blocks, the remaining sacrificial material having a substantially planarized upper surface;bonding a plurality of load-bearing spacers to the oxidizable material upper surface;after the bonding, removing the sacrificial material from the at least one region between the blocks;providing a base plate separated from the face plate by the spacers; andreducing a pressure between the face plate and base plate to form the evacuated display.
