  • Die attach using gold ribbon with gold/silicon eutectic alloy cladding
    Patent number: 5037778
    Abstract: An improved method for eutectically bonding a silicon wafer into a cavity of a packaging body. A gold/silicon eutectic alloy cladding is formed on a ribbon made of gold. A strip is cut from the ribbon and placed into the package cavity with the cladding side up. Then a die is placed onto the strip on top of the gold/silicon cladding. The die is then scrubbed at a temperature of approximately 400.degree. C. and the gold/silicon cladding acts as a catalyst to form a gold/silicon eutectic bond between the die and the packaging body.
