Title: Compound for forming electrode and manufacture of electrode
Inventor: BARET GUY
IPC: H01J11/12
Filed: 2000-05-19
Abstract: PROBLEM TO BE SOLVED: To increase conductivity of an electrode while increasing viscosity of silver grain by comprising conductive metal/alloy powder, meltable metal/ alloy powder in a material compound for forming an electrode. SOLUTION: A paste consisting of 50-87 wt.% of conductive metal, 3-30 wt.% of meltable metal, 8-35 wt.% of resin and 2-20 wt.% of an adhesion accelerator is used. The conductive metal is prepared by finely pulverizing silver with high conductivity, while the meltable metal is a metal melted at a low temperature below a heating temperature in manufacturing a tile for a plasma panel. The paste, an electrode and an insulating layer are heated simultaneously when direct screen printing is carried out. The reason for this is that the electrode cannot be stuck to a glass substrate by itself, though the size of the electrode is reduced when resin disappears once the meltable metal is melted.  A paste layer 12 is deposited on the electrode 11, and then, they are heated at 580 deg.C and cooled, so that, in a coupling area 13, the electrode 11 is fixed in a proper position on a substrate 10 by means of the insulating layer 12 stuck to the substrate 10 between the electrodes.
