  • Low Temperature High Strength Metal Stack for Die Attachment
    Publication number: 20120211793
    Abstract: A light emitting diode structure includes a diode region and a metal stack on the diode region. The metal stack includes a barrier layer on the diode region and a bonding layer on the barrier layer. The barrier layer is between the bonding layer and the diode region. The bonding layer includes gold, tin and nickel. A weight percentage of tin in the bonding layer is greater than 20 percent and a weight percentage of gold in the bonding layer is less than about 75 percent. A weight percentage of nickel in the bonding layer may be greater than 10 percent.
