摘要: A semiconductor device includes a post-passivation interconnect (PPI) structure having a landing pad region. A polymer layer is formed on the PPI structure and patterned with a first opening and a second opening to expose portions of the landing pad region. The second opening is a ring-shaped opening surrounding the first opening. A bump structure is formed on the polymer layer to electrically connect the landing pad region through the first opening and the second opening.

摘要: An embodiment of the disclosure includes a conductive feature on a semiconductor die. A substrate is provided. A bond pad is formed over the substrate. The bond pad has a first width. A polyimide layer is formed over the substrate and the bond pad. The polyimide layer has a first opening over the bond pad with a second width. A silicon-based protection layer overlies the polyimide layer. The silicon-based protection layer has a second opening over the bond pad with a third width. The first opening and the second opening form a combined opening having sidewalls to expose a portion of the bond pad. A UBM layer is formed over the sidewalls of combined opening to contact the exposed portion of the bond pad. A conductive feature overlies the UBM layer.
