Patent ID: 8349658

Claim:
A method of making a semiconductor device, comprising: providing a prefabricated multi-die leadframe including a base with an integrated raised die paddle and a plurality of bodies extending from the base with a surface of the bodies opposite the base vertically offset from a surface of the raised die paddle opposite the base; providing a plurality of semiconductor die; forming a thermal interface layer over a back surface of the semiconductor die or top surface of the raised die paddle; mounting the semiconductor die over theraised die paddle between the bodies of the leadframe with the thermal interface layer disposed between the semiconductor die and raised die paddle; depositing an encapsulant over the leadframe and semiconductor die; forming an interconnect structure vertically over the leadframe, semiconductor die, and a top surface of the encapsulant, the bodies being electrically connected to the interconnect structure; and removing the base to separate the bodies from the raised die paddle, wherein the raised die paddle provides heat dissipation for the semiconductor die.
