Solder ball fabricating process
A solder ball fabricating process for forming solder balls over a wafer having an active layer is provided. A patterned solder mask layer is formed over the active surface of the wafer. The patterned solder mask layer has an opening that exposes a bonding pad on the wafer. Solder material is deposited into the opening over the bonding pad. A reflow process is conducted to form a pre-solder body. The aforementioned steps are repeated so that various solder materials are fused together to form a solder ball over the bonding pad.
