摘要: In an aperture for use in an ion beam optical system having its surface coated with a liquid metal, instability of an ion source attributable to sputtering and re-deposition of an aperture base material is prevented. A focused ion beam apparatus using a liquid metal ion source has an aperture for limiting an ion beam diameter. The aperture has a vessel formed with a recess having, at its surface lowermost point, an aperture hole through which the ion beam passes and a liquid metal mounted on the recess, the liquid metal being used for the liquid metal ion source. Preferably, the aperture may be minimized in area of aperture entrance hole inner surface which exposes the base material by tapering an aperture hole portion, by which the ion beam passes, on the downstream side.

摘要: An emitter of a Ga liquid metal ion source is constituted to include W12 of a base material and Ga9 of an ion source element covering a surface as construction materials. By making back-sputtered particles become elements (W and Ga) of the Ga liquid metal ion sour source, if back-sputtered particles attach to the Ga liquid metal ion source, contamination which may change physical characteristics of Ga9 does not occur. A W aperture is used as a beam limiting (GUN) aperture to place Ga of approx. 25 mg (of melting point of 30° C.) on a surface of a portion included in a beam emission region (Ga store). When emitting ions to the beam limiting (GUN) aperture, Ga in the emission region melts and diffuses on a surface of the beam emission region of the W aperture.

摘要: In addition to the conventional test pattern writing in a center of each track and inspection of burst patterns (A and B patterns) through a writing test in a SAT, there is also performed a test pattern data writing test, which is done at each boundary between tracks. With this additional test, it is possible to accurately inspect both C and D burst patterns that are sensitive to a PES signal at each boundary between tracks.
