Publication number: 20160056016Abstract: Provided is an ion beam processing apparatus including an ion generation chamber, a processing chamber, and electrodes to form an ion beam by extracting ions generated in the ion generation chamber to the processing chamber. The electrodes includes a first electrode disposed close to the ion generation chamber and provided with an ion passage hole to allow passage of the ions, and a second electrode disposed adjacent to the first electrode and closer to the processing chamber than the first electrode is, and provided with an ion passage hole to allow passage of the ions. The apparatus also includes a power unit which applies different electric potentials to the first electrode and the second electrode, respectively, so as to accelerate the ions generated by an ion generator in the ion generation chamber. A material of the first electrode is different from a material of the second electrode.Type: ApplicationFiled: October 8, 2015Publication date: February 25, 2016Inventors: Yasushi Yasumatsu, Naoyuki Okamoto, Masashi Tsujiyama, Fumihito Suzuki

Publication number: 20150287567Abstract: An object of the invention is to provide a grid assembly which is easy to assemble and is high in assembly reproducibility, and an ion beam etching apparatus including it. A grid assembly is constructed of three grids each in the shape of a circular plate, which are stacked one on top of another. The grid assembly includes three fixing holes for fixing the three grids, and three positioning holes for positioning the three grids. In assembly, the three grids are stacked one on top of another on a first ring so that positioning pins provided on the first ring are inserted into the positioning holes. Then, a second ring is stacked on top of the three grids, and bolts are inserted into the fixing holes. Thus, positioning is performed by using the fixed positioning pins and thereafter the fixing can be performed, which facilitates the assembly.Type: ApplicationFiled: June 17, 2015Publication date: October 8, 2015Inventors: MASASHI TSUJIYAMA, YASUSHI YASUMATSU, KAORI MOTOCHI
