    摘要: A localized nanostructure growth apparatus that has a partitioned chamber is provided, where a first partition includes a scanning probe microscope (SPM) and a second partition includes an atomic layer deposition (ALD) chamber, where the first partition is hermetically isolated from the second partition, and at least one SPM probe tip of the SPM is disposed proximal to a sample in the ALD chamber. According to the invention, the hermetic isolation between the chambers prevents precursor vapor from damaging critical microscope components and ensuring that contaminants in the ALD chamber can be minimized.

    摘要: In a scanning atom probe (100), a surface topography of a specimen (3) is firstly analyzed by a surface topography analyzing unit (20). In the next place, an extraction electrode (5) is aligned to a desired area to be analyzed of a specimen surface. In case of analyzing electronic state of the area to be analyzed, negative bias voltage is impressed onto the specimen (3) from a direct current high voltage supply (2) and field emitted electrons are detected by a screen (9). In case of analyzing atomic arrangement and composition of the area to be analyzed, positive voltage is impressed onto the specimen (3) from the direct current high voltage supply (2) and a pulse generator (1) and positive ions generated by field evaporation are detected by a position sensitive ion detector (11) or a relfectron type mass analyzer (13).
