Patent number: 9207531Abstract: According to one embodiment, a pattern including first and second block phases is formed by self-assembling a block copolymer onto a film to be processed. The entire block copolymer present in a first region is removed under a first condition by carrying out energy beam irradiation and development, thereby leaving a pattern including the first and second block phases in a region other than the first region. The first block phase present in a second region is selectively removed under a second condition by carrying out energy beam irradiation and development, thereby leaving a pattern including the first and second block phases in an overlap region between a region other than the first region and a region other than the second region, and leaving a pattern of second block phase in the second region excluding the overlap region. The film is etched with the left patterns as masks.Type: GrantFiled: September 22, 2011Date of Patent: December 8, 2015Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Hiroko Nakamura, Koji Asakawa, Shigeki Hattori, Satoshi Tanaka, Toshiya Kotani
