Patent ID: 8466543

Claim:
An apparatus to connect integrated circuit devices, the apparatus comprising: a primary integrated circuit device; a plurality of primary electrically conductive contacts electrically coupled to a surface of the primary integrated circuit device, the plurality of primary electrically conductive contacts forming a pattern corresponding to secondary electrically conductive contacts disposed on one or more secondary integrated circuit devices; and a plurality of primary electrically conductive pillars electrically coupled to the surface of the primary integrated circuit device, the plurality of primary electrically conductive pillars extending away from the surface of the primary integrated circuit device, the plurality of primary electrically conductive pillars forming a pattern corresponding to substrate electrically conductive contacts disposed on a substrate, the plurality of primary electrically conductive pillars and associated connecting material providing a standoff height between the primary integrated circuit device and the substrate that is greater than or equal to a height of the one or more secondary integrated circuit devices, wherein the plurality of primary electrically conductive pillars support the primary integrated circuit device without a substrate surrounding the plurality of primary electrically conductive pillars in a space between the primary integrated circuit and the substrate with the electrically conductive contacts.
