Patent number: 10096448Abstract: An electromagnetic lens for charged particle beam exhibits positive spherical aberration. A complicated combination of electromagnetic lenses had been necessary for correcting this spherical aberration. One of a circular aperture or a ring-shaped aperture is provided on an incident plate arranged on an incident side of charged particle beam, another of the circular aperture or the ring-shaped aperture is provided on a plate arranged on an emission side thereof, and a voltage is applied between the incident plate and the emission plate. By so doing, an electric field generated in the ring-shaped aperture emanates, which resolves the positive spherical aberration. The spherical aberration can be corrected by an extremely simple and easily implemented structure.Type: GrantFiled: February 8, 2016Date of Patent: October 9, 2018Assignee: NATIONAL UNIVERSITY CORPORATION NAGOYA UNIVERSITYInventors: Tadahiro Kawasaki, Takayoshi Tanji, Takashi Ikuta

Patent number: 7034295Abstract: A photoemission electron microscopy having a light source system for carrying out a high-resolution measurement such as work function distribution measurement or magnetic domain distribution with reliability, and a high-sensitivity measurement method using the photoemission electron microscopy. A photoemission electron microscopy having an excitation light source system in which a specimen is irradiated with irradiation light from a light source uses a vacuum chamber in which the specimen is placed and an objective lens which collects the irradiation light on a specimen surface. The objective lens is accommodated in the vacuum chamber. The light source may be placed outside the vacuum chamber. A condenser lens which makes the irradiation light from the light source generally parallel may be placed between the light source and the vacuum chamber. A transmission window which transmits the irradiation light while the vacuum chamber is sealed may be placed between the condenser lens and the objective lens.Type: GrantFiled: September 10, 2004Date of Patent: April 25, 2006Assignees: ULVAC-PHI, Inc., Takanori KoshikawaInventors: Takanori Koshikawa, Takashi Ikuta, Tsuneo Yasue, Masami Taguchi, Ibuki Tanaka

Patent number: 4713687Abstract: A scan line type dynamic observation apparatus suitable for obtaining a static image of specific phase by successively sampling signals of specific phases from image signals of an object of observation which varies at a period particularly several Hz to several KHz. Sampling of signal is performed not in terms of a signal corresponding to a single point on a display image plane but every scanning line forming an image, thereby reducing image forming time. Also, sampling is performed at plural phase positions which repeatedly vary to display a scanning line corresponding thereto at a specific position on the image plane, whereby static images of plural specific phases can be simultaneously displayed on one and the same image plane.Type: GrantFiled: January 13, 1986Date of Patent: December 15, 1987Assignee: Research Development Corporation of JapanInventors: Ryuichi Shimizu, Takashi Ikuta
