Abstract
A semiconductor structure includes a semiconductive substrate, a post passivation interconnect (PPI) and a polymer layer. The PPI is disposed above the semiconductive substrate and includes a landing area for receiving a conductor. The polymer layer is on the PPI, wherein the conductor is necking a turning point so as to include an oval portion being substantially surrounded by the polymer layer, and the oval portion of the conductor is disposed on the landing area of the PPI.
