摘要：
A system and method for forming metal bumps is provided. An embodiment comprises attaching conductive material to a carrier medium and then contacting the conductive material to conductive regions of a substrate. Portions of the conductive material are then bonded to the conductive regions using a bonding process to form conductive caps on the conductive regions, and residual conductive material and the carrier medium are removed. A reflow process is used to reflow the conductive caps into conductive bumps.
