Semiconductor package
A semiconductor package that includes a semiconductor die and a heat spreader thermally coupled to the semiconductor and disposed at least partially within the molded housing of the package.
1. A semiconductor package, comprising:
a plurality of leads;
a semiconductor die including a first surface;
a first conductive interconnect body interposed between said first surface of said semiconductor die and a respective lead;
a metallic heat spreader including a first face having a first lateral dimension and a second opposing face having a second lateral dimension wider than said first lateral dimension, said first face thermally and mechanically coupled using a layer of thermally and electrically conductive adhesive to a second surface of said semiconductor die opposite said first surface, wherein said second surface is electrically inactive and has a third lateral dimension wider than said first lateral dimension, and wherein said first face substantially covers an entirety of said second surface;
a die pad;
a molded housing encapsulating said semiconductor die, a portion of said die pad, each said first conductive interconnect body, and at least part of said metallic heat spreader; and
a second interconnect body interposed between said first surface of said semiconductor die and said die pad, wherein said die pad is disposed between and lateral to said plurality of leads.
2. The semiconductor package of claim 1 , wherein said first and second conductive interconnect bodies are solder bumps.
3. The semiconductor package of claim 1 , wherein said first and second conductive interconnect bodies are copper bumps.
4. The semiconductor package of claim 1 , wherein said first and second conductive interconnect bodies are gold bumps.
5. The semiconductor package of claim 1 , wherein said first and second conductive interconnect bodies are pillar bumps.
6. The semiconductor package of claim 1 , wherein said semiconductor package is a QFN package.
7. The semiconductor package of claim 1 , wherein said thermally and electrically conductive adhesive is an epoxy.
8. The semiconductor package of claim 1 , wherein said thermally and electrically conductive adhesive is a solder.
9. The semiconductor package of claim 1 , wherein said metallic heat spreader is comprised of a copper slug.
10. The semiconductor package of claim 9 , wherein said copper slug is encapsulated by said molded housing.
