摘要：
A method of coupling an integrated circuit to a substrate includes providing the substrate, forming a contact pad in the substrate, contacting the contact pad with a solder ball, and repeatedly exposing the solder ball to a thermal process to cause intermetallics based on a metal in the contact pad to be formed in the thermal ball.
