Publication number: 20090267003Abstract: The exposure device is able to supply only EUV radiation to a mask, while eliminating radiation other than the EUV radiation. A multi layer made from a plurality of Mo/Si pair layers is provided upon the front surface of a mirror, and blazed grooves are formed in this multi layer. Radiation which is incident from a light source device is incident upon this mirror, and is reflected or diffracted. Since the reflected EUV radiation (including diffracted EUV radiation) and the radiation of other wavelengths are reflected or diffracted at different angles, accordingly their directions of progression are different. By eliminating the radiation of other wavelengths with an aperture and/or a dumper, it is possible to irradiate a mask only with EUV radiation of high purity.Type: ApplicationFiled: May 20, 2009Publication date: October 29, 2009Applicants: Komatsu Ltd., Gigaphoton Inc.Inventors: Masato MORIYA, Osamu WAKABAYASHI, Georg SOUMAGNE

Patent number: 6994748Abstract: A melt level or the gap between a melt surface and a heat shield is measured accurately irrespective of how the melt surface is. A laser beam from a range-finding unit is reflected by a scanning mirror and projected on a melt surface through an entrance window and a quartz prism in a chamber of a puller. After specular reflection, the beam forms a measurement spot in the bottom of a heat shield and scatters. Part of the scatter, after specular reflection at the melt surface (secondary reflection), passes through the prism, the entrance window and the scanning mirror to the range-finding unit. The range-finding unit carries out triangulation using the distance between a laser source and a photodetector therein, and the angle of incidence and the angle of the received laser beam.Type: GrantFiled: May 1, 2001Date of Patent: February 7, 2006Assignee: Komatsu Denshi Kinzoku Kabushiki KaishaInventors: Masato Moriya, Tadayuki Hanamoto, Hiroshi Monden, Toshio Hayashida, Toshirou Kotooka

Patent number: 6572699Abstract: A melt level detector is provided for detecting the melt level of a CZ furnace by triangulation. The laser beam (2) from a laser source (1) is moved in radial directions of a crucible (14) in the CZ furnace to find a location where a photodetector system (5, 7) can receive the reflection (4) from the melt level (3), and the laser beam (2) is fixed at the location. Since the measurements thus take place within an extremely small angular range of the laser beam, the melt level (3) can be detected with little effect of noise on the melt level (3) while eliminating complexity of the device.Type: GrantFiled: September 14, 2001Date of Patent: June 3, 2003Assignee: Komatsu Denshi Kinzoku Kabushiki KaishaInventors: Masato Moriya, Tadayuki Hanamoto, Kazuhiro Mimura, Toshirou Kotooka
