    摘要: According to a method of manufacturing carbon nanotubes, minute concavities and convexities are formed at a surface of a substrate, a catalyst metal layer having a predetermined film thickness is formed on the surface having the concavities and convexities, the substrate is subject to a heat treatment at a predetermined temperature to change the catalyst metal layer into a plurality of isolated fine particles. The catalyst metal fine particles have a uniform particle diameter and uniform distribution. Then, the substrate supporting the plurality of fine particles is placed in a carbon-containing gas atmosphere to grow carbon nanotubes on the catalyst metal fine particles by a CVD method using the carbon-containing gas. The carbon nanotubes can be formed to have a desired diameter and a desired shell number with superior reproducibility.

    摘要: A semiconductor device includes a semiconductor chip having an electric circuit; and a cooling device including at least one channel serving as a flow path through which coolant flows, an external surface including projections, and a metallic layer formed over the external surface including the projections. In the semiconductor device, the projections of the external surface of the cooling device are brought into contact with a first surface of the semiconductor chip via the metallic layer such that the semiconductor chip is cooled by allowing the coolant to flow through the channel formed in the cooling device.
