Abstract:
A semiconductor device comprising:a leadframe comprising a chip mount pad for an integrated circuit chip and a plurality of lead segments having their first end near said mount pad and their second end remote from said mount pad; said leadframe made of a base metal having a surface layer created by converting a percentage of said base metal atoms into substitutional metal complexes; an integrated circuit chip attached to said mount pad by a polymeric chip attach material; bonding wires interconnecting said chip and said first ends of said lead segments; encapsulation material surrounding said chip, said bonding wires and said first ends of said lead segments, whereby the adhesion between said encapsulation material and said surrounded parts is enhanced; and said encapsulation material leaving said second ends of said lead segments exposed, whereby said second ends are suitable for bending, for solder attachment to other parts, and for corrosion protection.
