Patent ID: 8309051

Claim:
A method for manufacturing multiple carbon nanotube heat sinks, comprising: providing a board, a first substrate, and a second substrate wherein the board has a top surface and a bottom surface opposite to the top surface, a plurality of grooves is defined on the top surface of the board, each groove has an inner bottom surface, the top surface of the board is defined as a first growing surface; growing a plurality of first carbon nanotubes on the first growing surface and growing a plurality of second carbon nanotubes on the inner bottom surfaces of the grooves, wherein free ends of the first carbon nanotubes are farther away from the bottom surface of the board than free ends of the second carbon nanotubes; fixing the free ends of the first carbon nanotubes into the first substrate; removing the first carbon nanotubes from the board so that the first carbon nanotubes remain embedded in the first substrate independently thereby forming a first carbon nanotube heat sink; fixing the free ends of the second carbon nanotubes into the second substrate; and removing the second carbon nanotubes from the board so that the second carbon nanotubes remain embedded in the second substrate independently thereby forming a second carbon nanotube heat sink.
