ABSTRACT:
A preferred method for making a field emission device (100) includes the steps of: providing an insulative substrate (101) with a surface (1011); defining a plurality of recesses (1012) in a desired pattern in the substrate; forming a cathode layer (104) in the recesses; forming a plurality of electron emitters (106) on the cathode; and forming a grid (111) on the surface of the substrate, such that the grid is insulated from the cathode.
