Patent ID: 8368214

Claim:
An apparatus, comprising: a semiconductor die having a plurality of integrated circuit devices; an interconnect layer disposed on the semiconductor die; a pad structure electrically coupled to at least one integrated circuit device of the plurality of integrated circuit devices via the interconnect layer; an electrically insulative layer disposed on the interconnect layer; a first shielding structure disposed within the electrically insulative layer, the first shielding structure further being electrically coupled to the pad structure; an under-ball metallization (UBM) structure electrically coupled to the first shielding structure; and a solder bump electrically coupled to the UBM structure, the solder bump comprising a solder bump material capable of emitting alpha particles, wherein the first shielding structure is positioned between the solder bump and the plurality of integrated circuit devices to shield the plurality of integrated circuit devices from the alpha particles emitted from the solder bump material.
