A wirebondless module package and method of fabrication including a molded preform of porous SiC with a cavity having therein an AlN substrate defining a plurality of pockets. The preform being infiltrated with Al and the Al being deposited in each of the pockets. A semiconductor die mounted on the Al in one of the pockets. A dielectric layer covering the Al and defining openings therethrough positioned to expose the aluminum and a connection to the die. A conductive material positioned on the dielectric layer in contact with the die and the Al so as to define terminals and interconnections between the die and the terminals.
