摘要: A method for wafer-level packaging includes providing a substrate having a conductive metal pad formed on the surface of the substrate; forming a metal core on the top of the conductive metal pad with the metal core protruding from the surface of the substrate; then, forming an under bump metal layer on the top surface and the side surface of the metal core; and finally, forming a bump structure on the top of the under bump metal layer.
