Patent ID: 7108575

Claim:
A method for fabricating a mesh structure mounted between an anode plate and a cathode plate of a tetraode field-emission display, comprising: forming a soft insulation coating layer on a flat film; laminating a metal conductive plate as a converging electrode layer with a plurality of first apertures to the coating layer, such that a filler of the coating layer is filled in each first aperture; removing the coating layer but remaining the filler in each first aperture after baking; forming another coating layer on the converging electrode layer as an insulation layer; sintering to harden the insulation layer; forming a gate layer with a plurality of third apertures corresponding to the first apertures on the insulation layer, respectively; sintering to have the gate layer firmly attached on the insulation layer; forming one protective layer on the gate layer with a plurality of through holes corresponding to the third apertures, respectively, such that a plurality of second apertures are formed on the insulation layer by etching; forming another protective layer on the converging electrode layer with another through hole corresponding to each first aperture, such that each filler is removed by etching; and removing the first and the second protective layers.
