Patent ID: 6951982

Claim:
A microelectronic component assembly comprising: a first microelectronic component package comprising: a first microelectronic component having a back surface; a first mold compound formed about the first microelectronic component, the first mold compound having a back surface; a plurality of first package contacts, each of which is exposed on the back surface of the first mold compound, at least some of the first package contacts being electrically coupled to the first microelectronic component; and a plurality of electrical connectors adapted for connection to another microelectronic component, the electrical connectors being accessible from a location spaced from the back surface of the first mold compound; and a second microelectronic component package comprising: a second microelectronic component having a back surface; a second mold compound formed about the second microelectronic component, the second mold compound having a back surface, the back surfaces of the first and second mold compounds being juxtaposed with but spaced from one another to define a peripherally open interpackage gap, the back surface of the first microelectronic component and the back surface of the second microelectronic component each being thermally exposed to the interpackage gap; and a plurality of second package contacts electrically coupled to the second microelectronic component, each second package contact being exposed on the back surface of the second mold compound and at least one of the second package contacts being electrically coupled to at least one of the first package contacts.
