摘要： A semiconductor leadframe structure (11,41) includes a die bond portion (12) and a plurality of leads (13) coupled to the die bond portion (12). The leadframe structure (11) comprises a metal (23) such as copper or a copper alloy. At least one lead (28,29) includes a bond post (31) that has a major surface (32) for forming a wire bond. The major surface (32) includes an exposed area (33) of leadframe metal (23) and a covered area (34) of another metal (24) deposited onto the leadframe metal (23).
