ABSTRACT:
A method for manufacturing an ultrafine carbon fiber of the present invention has several steps as follows. In the first step, a semiconductor film is formed over a surface having insulative. In the second step, a first treatment is performed so that a metal element or a silicide of the metal element is segregated on a crystal grain boundary of the semiconductor film after adding the metal element in the semiconductor film. In the third step, a second treatment is performed so that an ultrafine carbon fiber on the surface of the metal element or the silicide of the metal element is formed.
