METHOD AND APPARATUS USING NANOTUBES FOR COOLING AND GROUNDING DIE

摘要

AN EMBODIMENT OF THE PRESENT INVENTION DESCRIBED AND SHOWN IN THE SPECIFICATION AND DRAWINGS IS A PROCESS AND A PACKAGE FOR FACILITATING COOLING AND GROUNDING OF A SEMICONDUCTOR DIE [12] USING CARBON NANOTUBES [38] IN A THERMAL INTERFACE LAYER [26] BETWEEN THE DIE [12] AND A THERMAL MANAGEMENT AID. THE EMBODIMENTS THAT ARE DISCLOSED HAVE THE CARBON NANOTUBES [38] POSITIONED AND SIZED TO UTILIZE THEIR HIGH THERMAL AND ELECTRICAL CONDUCTANCE TO FACILITATE THE FLOW OF HEAT AND CURRENT TO THE THERMAL MANAGEMENT AID. ONE EMBODIMENT DISCLOSED HAS THE CARBON NANOTUBES [38] MIXED WITH A PASTE MATRIX BEFORE BEING APPLIED. ANOTHER DISCLOSED EMBODIMENT HAS THE CARBON NANOTUBES [38] GROWN ON THE SURFACE [16] OF THE SEMICONDUCTOR DIE [12].(FIG 3)
