International Classification:

H01J 17/49

US Classification:

313586, 445 23

Abstract:

A process for reducing Ag electromigration in electronic circuitry includes the step of treating the electronic circuitry with an electromigration resistant composition. This process is useful in fabricating electronic devices having electronic circuitry that is close together, such as resistors, capacitors, and displays, e. g. , a plasma display panel (PDP) or a liquid crystal display (LCD).
