Latest Patents

Kobayashi holds a patent for an Ag—Au—Pd ternary alloy bonding wire. This innovative wire is designed for semiconductor devices and consists of 4-10 mass % of gold with a purity of 99.999% or higher, 2-5 mass % of palladium with a purity of 99.99% or higher, and the remaining mass % of silver (Ag) with a purity of 99.999% or higher. The wire also contains 15-70 mass ppm of oxidizing non-noble metallic elements. It undergoes thermal annealing before being continuously drawn through dies and is thermally tempered afterward. This wire is particularly useful for ball bonding in a nitrogen atmosphere. The AgAl and a Pd-rich layer produced at the interface between the Ag—Au—Pd ternary alloy wire and an aluminum pad help suppress corrosion development between the AgAl intermetallic compound layer and the wire.
