IPC: H01L21/48 ,  H01L23/498 ,  H01L21/311 ,  H01L21/3213 ,  C23C18/54 ,  C23C28/02 ,  C25D7/12

Abstract: A package including a first carrier, a seed layer, wires, a die and a molding material is provided. The first carrier is removed to expose the seed layer after disposing a second carrier on the molding material, then the seed layer is removed to expose the wires, and a gold layer is deposited on each of the wires by immersion gold plating, finally a semiconductor device is obtained. The gold layer is provided to protect the wires from oxidation and improve solder joint reliability.
