Abstract:
A system and method for imaging a sample having a complex structure (such as an integrated circuit). The sample is placed on a motion system that moves the sample with respect to an electron beam generator that is used in imaging the sample. The motion system affords thirteen degrees-of-freedom for movement of the sample, by providing a rotation stage, a fine 6-axis piezoelectric-driven stage, and a coarse 6-axis hexapod stage. Various detectors gather information to image the sample. Interferometric and/or capacitive sensors are used to measure the position of the sample and motion system.

Claim (Index 8):
A system for imaging a sample, the system comprising:\n a sample holder configured to secure the sample within a vacuum chamber; an electron beam generator configured to produce an electron beam within the vacuum chamber; a coarse motion stage positioned within the vacuum chamber, the coarse motion stage providing movement along a first axis that provides a first degree-of-freedom, movement along a second axis perpendicular to the first axis that provides a second degree-of-freedom, movement along a third axis perpendicular to the first and second axes that provides a third degree-of-freedom, rotation around the first axis that provides a fourth degree-of-freedom, rotation around the second axis that provides a fifth degree-of-freedom, and rotation around the third axis that provides a sixth degree-of-freedom; a fine motion stage positioned within the vacuum chamber laterally above the coarse motion stage, the fine motion stage providing movement along a fourth axis that provides a seventh degree-of-freedom, movement along a fifth axis perpendicular to the fourth axis that provides an eighth degree-of-freedom, movement along a sixth axis perpendicular to the fourth and fifth axes that provides a ninth degree-of-freedom, rotation around the fourth axis that provides a tenth degree-of-freedom, rotation around the fifth axis that provides an eleventh degree-of-freedom, and rotation around the sixth axis that provides a twelfth degree-of-freedom; and a rotation stage positioned within the vacuum chamber laterally above the fine motion stage, the rotation stage providing rotation around a seventh axis that provides a thirteenth degree-of-freedom.
