Patent number: 9400477Abstract: A cleaning device includes a cleaning member that includes a cleaning portion that cleans a light transmission member, which has a substantially elongated shape and which transmits light, and a support portion that supports the cleaning portion and a wall portion that is disposed on one end side of the light transmission member in a longitudinal direction of the light transmission member and that has a surface that is formed along a direction that intersects the longitudinal direction of the light transmission member. The cleaning member and the wall portion each have a configuration in which when an end of the cleaning member makes contact with the wall portion and is pressed, the support portion is bent in a convex manner toward a side opposite to a side on which the light transmission member is disposed.Type: GrantFiled: June 20, 2014Date of Patent: July 26, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Satoru Nishikawa, Akira Numazaki, Hirotake Eguchi, Shinya Mitorida, Satoshi Takada, Taichi Fuchu, Nobuyuki Otani

Patent number: 9298159Abstract: A removal mechanism includes a removing member, an accommodation section, a receiver, and a cooling path. The removing member rubs against an extraneous-matter-adhered member, to which extraneous matter is adhered, so as to remove the extraneous matter therefrom. The accommodation section accommodates therein the extraneous matter removed by the removing member. The receiver receives, at a lower side of the accommodation section, the extraneous matter spilling out and dropping from the accommodation section. The cooling path allows gas so flow therethrough so as to cool the accommodation section from outside thereof. The cooling path is spatially isolated from a passage chamber through which the extraneous matter dropping from the accommodation section toward the receiver passes, an accommodation chamber for the extraneous matter in the accommodation section, and a chamber above the receiver that receives the extraneous matter.Type: GrantFiled: June 4, 2014Date of Patent: March 29, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Shinya Mitorida, Satoru Nishikawa, Akira Numazaki, Satoshi Takada, Taichi Fuchu, Hirotake Eguchi

Publication number: 20150357158Abstract: An object of the present invention is to provide a method for pattern measurement and a charged particle radiation device in which a pattern formed by using a DSA technique can be very precisely measured and inspected. According to an aspect for achieving the object, a method for pattern measurement or a charged particle radiation device for realizing the measurement is proposed as follows. A charged particle is radiated to a polymer compound used for a self-organization lithography technique, and a specific polymer is considerably contracted as compared to the other polymer among multiple polymers forming the polymer compound. Thereafter, dimensions between multiple edges of the other polymer are measured, based on a signal obtained by scanning a region including the other polymer with the charged particle beam.Type: ApplicationFiled: January 22, 2014Publication date: December 10, 2015Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Makoto SUZUKI, Satoru YAMAGUCHI, Kei SAKAI, Miki ISAWA, Satoshi TAKADA, Kazuhisa HASUMI, Masami IKOTA

Patent number: 8822920Abstract: In recent years, in association with the miniaturization and high integration of semiconductor manufacturing processes, there have been arising many cases where observation target portions are densely located. In such a case, if observation is performed using a conventional pre-charge technology, scanning with an electron beam in pre-charging are repeatedly executed, therefore the charge potential on the surface of a specimen exceeds the dielectric breakdown voltage. As a result, dielectric breakdown arises in areas where scanning with an electron beam are repeatedly executed. An object of the present invention is to provide a defect observation method that can reduce the risk of dielectric breakdown, and a charged particle beam apparatus that utilizes the method. In the present invention, when a specimen is observed with the use of a technology relevant to pre-charging, after executing a piece of control processing, plural images are photographed.Type: GrantFiled: June 15, 2011Date of Patent: September 2, 2014Assignee: Hitachi High-Technologies CorporationInventors: Tatsuichi Katou, Satoshi Takada

Publication number: 20140084159Abstract: In related art, when a location to be analyzed is selected from inspection data, a relatively highly critical defect among entire defects is not selected as a defect to be analyzed. Further, when a mark is placed in a fixed position associated with a defect, the mark affects the defect itself depending on the shape and size of the defect, which is problematic in the following analysis made in an analysis apparatus. Moreover, in the case of a wafer with no pattern, a defect invisible to a SEM cannot be marked. To select a highly critical defect as a defect to be analyzed, an automatic classification result from a review SEM is used to select a defect to be analyzed. Further, to avoid an effect on a defect itself, a mark is placed in a position associated with the defect with the distance from the defect to the marking position changed on a defect basis.Type: ApplicationFiled: March 14, 2012Publication date: March 27, 2014Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Kaori Yaeshima, Satoshi Takada, Fumiaki Endo, Tetsuya Niibori

Patent number: 7663067Abstract: A first gate opens obliquely downward, and maintains the posture, rendering the slope angle of the bottom surface thereof steeper than that of the bottom surface of the second gate. Thus, the bottom surface of the second gate forms a gentle slope sliding surface, and the bottom surface of the first gate forms a steep slope sliding surface. Then articles drop following the shape of a parabola toward the bottom surface of the first gate on the steep slope side, with momentum gained from sliding down the bottom surface of the second gate on the gentle slope side, and then change the sliding trajectory inward upon bumping into the bottom surface of the first gate. The articles then drop following the shape of a parabola toward the center area of a dispersal table, with momentum gained from sliding down the bottom surface of the first gate.Type: GrantFiled: August 9, 2007Date of Patent: February 16, 2010Assignee: Ishida Co., Ltd.Inventors: Teruo Hayakawa, Takao Kihara, Noboru Kobayashi, Satoshi Takada, Koichi Makino
