Three dimensional integrated circuit package

Claim 1

A three-dimensional high density integrated circuit package comprising a. at least two integrated circuit layers, each of said layers having a first face and a second face and a plurality of edges, wherein at least a portion of the respective faces of said layers are juxtaposed in a face-to-face contacting relationship forming an integral, hermetically sealed stack of said layers, and further wherein each of said layers is an integral unit including: (1) a substrate member, including a plurality of operative connectors, (2) at least one integrated circuit chip member mounted on each said substrate, said chip being operatively coupled to said connectors, and (3) a spacer member having a central aperture surrounding each said chip on each said substrate, said layers each including one or more vertical grooves formed therethrough so as to be in alignment with one another, b. conductive pin means for operatively interconnecting internally within said package through said aligned grooves any one or more of said connectors on any one of said layers with any one or more of said connectors on any other said layer, whereby at least one of said connectors communicates with one or more external circuits, said package further comprising heatsink members interspersed at predetermined intervals between said layers to provide lateral heat dissipation for each of said layers.
