摘要： A method of attaching a metal clip to a semiconductor die includes: aligning a first bonding region of the metal clip with a first bond pad of the semiconductor die; and while the first bonding region of the metal clip is aligned with the first bond pad of the semiconductor die, forming a plurality of first wire bonds to the first bond pad of the semiconductor die through a plurality of openings in the first bonding region of the metal clip, the plurality of first wire bonds forming a joint between the metal clip and the first bond pad of the semiconductor die. Additional methods and related semiconductor packages produced from such methods are also described.

摘要： A semiconductor package includes: a substrate having a metallic surface; a semiconductor die metallurgically bonded to the metallic surface of the substrate by a first solder joint; and a solder wetting structure metallurgically welded to the metallic surface of the substrate outside a perimeter of the semiconductor die and adjacent to one or more side faces of the semiconductor die. Excess solder squeezed out from under the semiconductor die is metallurgically bonded to the solder wetting structure. Methods of producing the semiconductor package and solder wetting structure are also described.
