Publication number: 20070128559Abstract: A raw material of a cover layer as a material for forming a fine pattern is applied as to cover a resist pattern. Then, a component in the cover layer permeates into the resist pattern. Thereby, a mixed layer having a lower softening point than that of the resist pattern is formed. Then, a heat treatment is performed at a temperature lower than the softening point of the resist pattern and higher than that of the mixed layer. Thereby, the mixed layer is softened and a width of the mixed layer becomes large. As a result, a space of the resist pattern is narrowed. Therefore, a fine pattern is formed having a smaller size than the size limit due to the exposure wavelength.Type: ApplicationFiled: November 17, 2006Publication date: June 7, 2007Applicant: Renesas Technology Corp.Inventors: Takeo ISHIBASHI, Tetsuro Hanawa, Mamoru Terai, Teruhiko Kumada
