Title:
ABERRATION CORRECTION DEVICE AND CHARGED PARTICLE BEAM DEVICE EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2012/014870
Kind Code:
A1
Abstract:
To provide an aberration correction device and a charged particle beam device employing same that are jointly usable with a tunneling electron microscope (TEM) and a scanning tunneling electron microscope (STEM), an aberration correction device (1) comprises, between a TEM objective lens (6a) and an STEM objective lens (6b): a transfer lens group (4, 5), for transferring a coma-free surface (11) of the TEM objective lens (6a) to a multipolar lens (3); a transfer lens group (7, 8) for transferring the coma-free surface of the TEM object lens to a multipolar lens (2); and a transfer lens (13) for correcting fifth-order spherical aberration of the STEM objective lens (6b).
