Title:
CONDUCTIVE ADHESIVES, AND MOUNTED STRUCTURE USING THE SAME
Document Type and Number:
Japanese Patent JP3450839
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a conductive adhesives and a mounted structure using the same which maintain a moisture resistant reliability even when an ordinary base metal electrode is used.
SOLUTION: The conductive adhesives contains the first particle of which a standard electrode potential is higher than the standard electrode potential of silver, and the second particle of which a standard electrode potential is lower than the standard electric potential of silver. On the surface of the electrode with a potential lower than the potential of metal particle, which is the first particle, a metal compound film, with a potential higher than the potential of the metal particle, may be formed.
