Patent number: 9099283Abstract: A signal processing unit (21) of a charged particle microscope calculates a degradation function (H (s)) of an image, on the basis of detection signals (11) obtained by scanning a charged particle beam (2) at two types of scanning speeds, a scanning speed within the bandwidths of a detector (12) and an amplifying circuit at a subsequent stage of the detector, and another scanning speed exceeding the upper limit of the bandwidths. Then, the signal processing unit creates a one-dimensional correction filter for recovering image quality, from an inverse function (H?1 (s)) of the degradation function, and applies the one-dimensional correction filter to the detection signal recorded at the scanning speed exceeding the upper limit of the bandwidths of the detector and the amplifying circuit at a subsequent stage of the detector, or to a two-dimensional image based on the detection signal.Type: GrantFiled: November 8, 2010Date of Patent: August 4, 2015Assignee: Hitachi High-Technologies CorporationInventors: Yoshinobu Hoshino, Shigeru Kawamata, Eisaku Oho

Patent number: 9012842Abstract: A control device (50) for a charged particle beam device (100) tilts the irradiation axis of a primary electron beam (4) to the left, straight, or to the right via tilting coils (11, 12) each time the primary electron beam (4) scans the surface of a sample (15) over a single scanning line. When the irradiation axis is changed, the focal point of the primary electron beam (4) is adjusted by a focal point-adjusting coil (14) based on the tilt of the irradiation axis in order to take a left-tilted observation image, a non-tilted observation image or a right-tilted observation image of the surface of a sample (15) for each scanning line. The left-tilted observation images, non-tilted observation images and right-tilted observation images for the scanning lines obtained up to this point are simultaneously displayed on the same display device (31). In this way, focused non-tilted observation images and focused tilted observation images can be taken and displayed nearly simultaneously.Type: GrantFiled: December 20, 2012Date of Patent: April 21, 2015Assignee: Hitachi High-Technologies CorporationInventors: Wataru Kotake, Shigeru Kawamata, Sukehiro Ito
