Analysing a NAND Flash memory device using low kV EDS
应用领域
电子/电气检测样品
其他检测项目
分析NAND闪存Introduction
Historically energy dispersive X-ray spectroscopy has been focused towards high energies where X-ray lines are well separated
and the X-ray background is low. Recently the demand for higher spatial resolution, whether that is when analysing
semiconductor devices or measuring precipitates in metals, has increased dramatically. To ensure maximum sensitivity when
working under these demanding conditions the Ultim® range of EDS detectors combine the largest area SDD with optimised
geometries to consistently deliver a higher count rate.

元素构成分析Introduction
Application Note
As semiconductor devices continue to decrease in size to improve performance and take advantage of
advances in fabrication techniques, there is a need to analyse both their structure and chemistry at ever
increasing resolution. Typically this requires the use of TEM for metrology and failure analysis. Using ultrahigh
resolution FEG-SEM, low kV imaging and the new X-Max® Extreme EDS detector we demonstrate
the ability to retain some of this high resolution analysis in the SEM. This allows for better targeting of
resources and increased throughput of analysis.

理化分析Introduction
The groundbreaking Symmetry CMOS-based EBSD detector, together with the powerful AZtec® software, is capable
of acquiring EBSD and EDS data at speeds in excess of 3000 indexed patterns per second (pps). These speeds, twice
as fast as those achievable with conventional CCD-based detectors, are further enhanced by the fact that extreme
pixel-binning of the diffraction patterns is not necessary. This means that the quality of the data collected using
Symmetry is significantly better than with CCD-based detectors, both in terms of hit rate and also angular accuracy.
In this application note we give examples of how Symmetry can be used to characterise the microstructures in two
example metals at high speeds, providing reliable statistics in affordable timescales.

Simultaneous EDS and EELS Analysis in the TEM
应用领域

完全表征Introduction
In Transmission Electron Microscopy (TEM) there are two ‘go to’ techniques for elemental analysis: Energy
Dispersive X-ray Spectroscopy, (EDS), and Electron Energy Loss Spectroscopy, (EELS).
EDS is a mature technique that can be used for most specimens. The intensity of generated X-rays
is proportional to the mass thickness of the sample. However, this can become a limitation for very
thin specimens or those comprising light elements. On the other hand, EELS is more suitable for thin
samples where the thickness is less than the inelastic mean free path of electrons in the material. EELS
does, however, give high signal to noise for light elements. Simultaneous acquisition of both signals is a
powerful tool for materials analysis.

锡球测试空间能谱分辨率Testing EDS spatial resolution using a tin sphere on carbon
imaging standard
Using 2 kV at 5 mm WD, a spectrum image (6,500 cps, 15 minutes) was collected from an area of the standard where the
smallest spheres were concentrated. The X-ray data were reconstructed into a ‘layered map’ combining the Sn M (400 eV) and
O K signals from the Sn spheres (Fig. 1). Inspection of the image shows that spheres down to 10 nm in diameter are clearly
differentiated. Smaller spheres, which were measured at 7.5 nm, can also be distinguished in the image.

应用领域
钢铁/金属检测样品
其他检测项目
理化分析Transmission Kikuchi diffraction (TKD) is a relatively recent development in EBSD that allows high resolution analysis of electron
transparent samples. Most applications in the literature have used TKD for targeted measurements of relatively small areas, on
samples where conventional EBSD struggles to deliver the required resolution [1]. These samples are typically nanocrystalline
metals and alloys, although increasingly the technique is also being used to characterise highly
