Abstract:
A system and method for imaging a sample having a complex structure (such as an integrated circuit) implements two modes of operation utilizing a common electron beam generator that produces an electron beam within a chamber. In the first mode, the electron beam interacts directly with the sample, and backscattered electrons, secondary electrons, and backward propagating fluorescent X-rays are measured. In the second mode, the electron beam interrogates the sample via X-rays generated by the electron beam within a target that is positioned between the electron beam generator and the sample. Transmitted X-rays are measured by a detector within the vacuum chamber. The sample is placed on a movable platform to precisely position the sample with respect to the electron beam. Interferometric and/or capacitive sensors are used to measure the position of the sample and movable platform to provide high accuracy metadata for performing high resolution three-dimensional sample reconstruction.

Claim (Index 25):
The method of  claim 20 , further comprising :\n defining an optimal data acquisition strategy by assessing output from the inversion and identifying regions of the sample where convergence has not been met; acquiring third data in the second mode of operation using a multiresolution sampling strategy at the spectral X-ray detector, wherein the third data comprises X-ray transmission spectra corresponding to pixels of the spectral X-ray detector; and performing multiscale inversions on the X-ray transmission spectra.
