Field emission device and method for making the same

摘要

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.
