Abstract:
Presented herein are an interconnect structure and method for forming the same. The interconnect structure includes a contact pad disposed over a substrate and a connector disposed over the substrate and spaced apart from the contact pad. A passivation layer is disposed over the contact pad and over connector, the passivation layer having a contact pad opening, a connector opening, and a mounting pad opening. A post passivation layer including a trace and a mounting pad is disposed over the passivation layer. The trace may be disposed in the contact pad opening and contacting the mounting pad, and further disposed in the connector opening and contacting the connector. The mounting pad may be disposed in the mounting pad opening and contacting the opening. The mounting pad may be separated from the trace by a trace gap, which may optionally be at least 10 μm.
