发明名称 Bump-on-Trace Methods and Structures in Packaging
摘要 A method and structure for bump-on-trace bonding is provided. In an embodiment traces to be used for bump-on-trace (BOT) bonding are protected during a pre-solder treatment. The pre-solder treatment improves the adhesion between the exposed traces (e.g., the non-BOT traces) and a solder resist layer.

主权项 1. A method of forming an electrical device, the method comprising: providing a first substrate having a first trace and a second trace; forming a mask over the first trace; treating the second trace while the first trace is protected by the mask, the treating forming a treated portion of the second trace; removing the mask; and forming a protective layer directly over the treated portion of the second trace.
