US Patent:

20080265403, Oct 30, 2008
Filed:

Dec 23, 2005
Appl. No.:

11/306343
Inventors:

James Allen Cornie - Cambridge MA, US
Stephen Shawn Cornie - Watertown MA, US
Yuejian Chen - Clifton Park NY, US
Larry Ballard - Watertown MA, US
Assignee:

METAL MATRIX CAST COMPOSITES, LLC - Waltham MA
International Classification:

H01L 23/34
US Classification:

257706
Abstract:

A hybrid package for heat sinking a device is formed of a graphitic material that defines a plurality of cavities for cast-in-rivets and that defines at least one cavity for a cast-in-rivet via. The graphitic material is pressure infiltrated with a molten metal alloy so as to form a composite material with a plurality of cast-in rivets that increases at least one of the through-plane conductivity and the strength of the hybrid package and that forms at least one cast-in-rivet that increases an in-plane thermal conductivity of the hybrid package.
