A system and method to process horizontally aligned graphite nanofibers in a thermal interface material used in 3d chip stacks |
摘要 |
<p>The chip stack of semiconductor chips with enhanced cooling apparatus includes a first chip with circuitry on a first side and a second chip electrically and mechanically coupled to the first chip by a grid of connectors. The apparatus further includes a thermal interface material pad placed between the first chip and the second chip, wherein the thermal interface material pad includes nanofibers aligned parallel to mating surfaces of the first chip and the second chip. The method includes creating a first chip with circuitry on a first side and creating a second chip electrically and mechanically coupled to the first chip by a grid of connectors. The method further includes placing a thermal interface material pad between the first chip and the second chip, wherein the thermal interface material pad includes nanofibers aligned parallel to mating surfaces of the first chip and the second chip.</p> |
