A new technique from Pacific Northwest National Laboratory and FEI Company lets scientists efficiently resolve elements' locations in three dimensions. The team's technique combines scanning transmission electron microscopy and X-ray energy dispersive spectrometry with a new detector arrangement and a brighter electron beam. The result is a three-dimensional map of the elements' placement on a sample smaller than a single blood cell.

Continuing technological advances require the element analysis of increasingly smaller structures in many fields of materials science, including semiconductors and nanotechnology in general. The element composition of thin electron transparent samples can be analyzed in the nm-range using transmission electron microscopes (TEM) or, specific sample holders provided, in the field emission scanning electron microscope (FE-SEM). Nevertheless both methods often require complex sample preparation. An alternative method is to analyze bulk samples with a FE-SEM.

The development of modern technology affects the science of small objects in two ways. On one hand better means for handling, imaging and analysis of miniature objects are provided, which means we can try and understand our world on a much smaller scale. On the other hand further miniaturization in manufacturing necessitates the control of technological processes at a minimum of one order of magnitude below the aspired device size. The need for rapid and efficient nanoanalysis is growing very quickly. The next generation 22 nm node in microelectronics architecture is approaching.
