Thermally enhanced semiconductor package
摘要:
A semiconductor package with thermally enhanced properties is described. The semiconductor package includes a substrate upon which a die is affixed. The die and the substrate each have contacts which are respectively connected with each other. A heat sink is affixed to a surface of the die by way of a thermally compliant material. The compliant material reduces the stresses caused by temperature fluctuations which cause the heat sink and the die to expand and contract at different rates. A first molding material is deposited around the periphery of the die, compliant material and heat sink, thereby leaving exposed substantially an entire surface of the heat sink.
