Abstract:
1. A packaged semiconductor structure, comprising: a heat source; a heat sink; an aligned array of carbon nanotubes comprising a first portion of the carbon nanotubes formed, from a first direction directly on a first surface of the heat source, a second portion of the carbon nanotubes that is different in position from the first portion, formed from a second direction, distinct from the first direction, directly on a second surface of the heat sink, and a third portion of the carbon nanotubes that is different in position from the first portion and the second portion, formed from the first direction directly on the first portion to contact the second portion, wherein a first sidewall of the first portion of the carbon nanotubes and a second sidewall of the second portion of the carbon nanotubes overlap and connect, via the third portion, from the first direction and the second direction to thermally connect the heat source to the heat sink, thereby forming a structural gap between the heat source and the heat sink; and a peripheral connecting adhesive that runs along at least a portion of an outside edge of the structural gap and adheres and permanently bonds a portion of an outside surface of the heat source to outside edges of the first portion of the carbon nanotubes and the second portion of the carbon nanotubes.
