Adhesion between post-passivation interconnect structure and polymer |
摘要 |
An embodiment integrated circuit structure includes a substrate, a metal pad over the substrate, a post-passivation interconnect (PPI) structure over the substrate and electronically connected to the metal pad, a thin oxide film layer directly over a top surface of the PPI structure, and a polymer layer over the thin oxide film layer and PPI structure. |

1. An integrated circuit structure comprising:
a substrate; a metal pad over the substrate; a passivation layer over the substrate and covering an edge portion of the metal pad; a post-passivation interconnect (PPI) structure over the passivation layer and electronically connected to the metal pad; a thin oxide film layer directly over a top surface of the PPI structure; and a polymer layer over the thin oxide film layer and PPI structure. |
