Filed: 2009-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a much larger beam current and form a focused ion beam with smaller aberration than a conventional focused ion beam apparatus over low to high acceleration.  <P>SOLUTION: The focused ion beam apparatus includes: a liquid metal ion source; an extraction electrode for extracting an ion beam from the liquid metal ion source; an acceleration (ground) electrode for accelerating an ion beam; and an electrostatic lens for converging an ion beam; and is structured such that, when the acceleration voltage of the liquid metal ion source is lower than an emission threshold voltage of the liquid metal ion source, the voltage of the extraction electrode is set at a lower potential than that of the acceleration (ground) electrode. In the focused ion beam apparatus, the polarity of a voltage applied to the electrostatic lens is changed in conjunction with the polarity of a voltage applied to the extraction electrode. This invention makes it possible to exercise a deceleration mode focusing method at a high acceleration voltage from the dielectric strength voltage of the electrostatic lens, and exercise an acceleration mode focusing method at a low acceleration voltage with an electrostatic lens having the same focal length as for the deceleration mode focusing method.  <P>COPYRIGHT: (C)2010,JPO&INPIT
