Abstract

A Ti film is pattern-formed on a desired portion on a silicon substrate, and a Co film is formed on the substrate so as to cover the Ti film. CNTs are formed only on a portion, under which the Ti film is formed, of the surface of the Co film at approximately 600° C. by a thermal CVD method. The length of the CNT can be controlled by adjusting the thickness of the Ti film.
