Abstract:
There is provided a system and method for a spot plated leadframe and an IC bond pad via array design for copper wire. There is provided a semiconductor package comprising a leadframe having a pre-plated finish and a spot plating on said pre-plated finish, a semiconductor die including a bond pad on a top surface thereof, and a copper wire bonded to said spot plating and to said bond pad. Optionally, a novel corner via array design may be provided under the bond pad for improved package performance while maintaining the integrity of the copper wire bond. The semiconductor package may provide several advantages including high MSL ratings, simplified assembly cycles, avoidance of tin whisker issues, and low cost compared to conventional packages using gold wire bonds.
