Publication number: 20080157011Abstract: The present invention is made to provide an extreme ultraviolet light source target or an X-ray source target having a good operationality. An extreme ultraviolet light source target in accordance with an aspect of the present invention is obtained by including a heavy metal such as tin into a matrix made of a polymeric material such as hydroxylpropylcellulose (HPC). The target can be manufactured by mixing the heavy metal and the polymeric material with a solvent, and evaporating the solvent. Since the target uses the polymeric material as a matrix, the target can be easily deformed to have a desired shape. For this reason, the target can be easily attached to a target holder irrespective of the shape of the holder, resulting in a good operationality of the target. Furthermore, an emission efficiency can be improved by including the heavy metal at a low density.Type: ApplicationFiled: August 29, 2005Publication date: July 3, 2008Applicant: OSAKA UNIVERSITYInventors: Keiji Nagai, Qincui Gu, Takayoshi Norimatsu, Shinsuke Fujioka, Hiroaki Nishimura, Katsunobu Nishihara, Noriaki Miyanaga, Yasukazu Izawa

Publication number: 20060133574Abstract: An object of the present invention is to provide an extreme ultraviolet light source target which can emits extreme ultraviolet light with high emission efficiency. A solid target made of heavy metal or heavy-metal compound and having a density 0.5 to 80% that of the crystal density is used. When the target is irradiated with a laser beam, plasma of the heavy metal contained in the target is generated, and extreme ultraviolet light having a predetermined wavelength which corresponds to the kind of the heavy metal is emitted from the plasma. When the density of the target is made to be smaller than the crystal density as described above, space distribution of the density of the generated plasma can be controlled, and the region in which plasma absorbs energy of the laser beam overlaps the region in which the plasma emits the extreme ultraviolet light. Thus, emission efficiency can be improved, preventing energy loss.Type: ApplicationFiled: December 26, 2003Publication date: June 22, 2006Applicant: KANSAI TECHNOLOGY LICENSING ORGANIZATION CO., LTD.Inventors: Keiji Nagai, Hiroaki Nishimura, Takayoshi Norimatsu, Katsunobu Nishihara, Noriaki Miyanaga, Masahiro Nakatsuka, Yasukazu Izawa, Tatsuhiko Yamanaka, Mitsuo Nakai, Keisuke Shigemori, Masakatsu Murakami, Yoshinori Shimada, Shigeaki Uchida, Atsushi Sunahara, Vasilli Zhakhovski, Ryouji Matsui, Takahiro Hibino, Tomoharu Okuno

Patent number: 6337268Abstract: A contact structure is formed with no voids in an interlayer insulation film and good surface planarity. A first insulation film (21) formed of p-TEOS is deposited to cover a substrate (1) and wires (4) formed on the substrate (1). A second insulation film (22) which is coating glass is formed by SOG. The surface is etched back from the opposite side to the substrate (1); therefore, the second insulation film (22) is etched. The etching is stopped at the point where the surface (21a) of the first insulation film (21) on the wires (4) is exposed. This ensures good surface,planarity. A third insulation film (23) is stacked on top of the second insulation film (22), and portions of the third insulation film (23) above the wires (4) are isotropically etched to form openings (51). At this time, the isotropic etching does not extend over the second insulation film (22).Type: GrantFiled: July 5, 2000Date of Patent: January 8, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Shigenori Kido, Jiro Matsufusa, Tomoharu Mametani, Yoji Nakata, Takeshi Kishida, Yukihiro Nagai, Akinori Kinugasa, Hiroaki Nishimura
