Bonding structure and fabrication thereof
摘要:
A bonding structure and the method of fabricating the same are disclosed. The bonding structure of the invention includes a copper-based pad formed in an insulator layer and a protection layer substantially covering top surface of the copper-based pad. The protection layer is self-aligned formed and the material thereof is selected from a group consisting of metal nitride, copper alloy, copper compounds, and a combination thereof.
