Carbon nanotubes
A tube made from a sheet of graphite (the same materials used in pencils) that has been wrapped into a cylinder. As its name implies, the diameter of a nanotube ranges from 1 to 10 nanometers, while its length is several thousand times longer than its diameter. Carbon nanotubes have superior physical properties, including tough mechanical strength, chemical stability, high thermal conductivity, low resistance, high aspect ratio, and high allowable current density.
A mounting method for mounting onto a board. Rather than the conventional method of connecting to a board via metallic wires, the chip's circuitry side is connected directly to protruding electrodes on the board.
A protruding electrode formed on the surface of a semiconductor chip, used to connect semiconductors and boards. Materials used for bumps can be gold, solder, or carbon nanotubes.
