The device of this invention includes a semiconductor die attached to a bare copper lead frame and electrically coupled to a lead by a metal wire coated with a metallic material. The device would function similarly to devices where the lead frames were coated with other metallic materials, but at lower costs because instead of plating the lead frame the wire is plated. The wire can be either gold or aluminum. When the wire is gold, the coating may be silver or other suitable metallic materials. When the wire is aluminum, the coating may be nickel, palladium, or other suitable metals.
