Abstract
In a three-dimensional chip configuration, a heat spreading material may be positioned between adjacent chips and also between a chip and a carrier substrate, thereby significantly enhancing heat dissipation capability. Furthermore, appropriately sized and positioned through holes in the heat spreading material may enable electrical chip-to-chip connections, while responding thermally conductive connectors may extend to the heat sink without actually contacting the corresponding chips.
