Feature size and its potential to deviate from expectation, materials composition, and the relationship between small scale and large scale — these are common questions that can be resolved by SEM microanalysis.

Samples may vary in type, size, and shape, as well as in their individual preparation methods, therefore, an SEM workflow is the best choice for obtaining characterization data. The most common SEM workflow consists of three steps: navigation, sample contrast exploration (SE/BSE), and elemental inspection (EDS). The degree to which this workflow can be effortlessly and efficiently applied to the wide range of samples coming to the laboratory—while also maintaining the highest possible resolution and image quality—is one of the many key factors which define the productivity and success of materials research and development projects.

At their market introduction, TESCAN´s VEGA and MIRA SEMs were designed to allow users performing this common workflow to do so intuitively and efficiently. In this webinar, we will show how new features on TESCAN’s 4th Generation VEGA and the FEG-SEM MIRA make a conventional analytical workflow more intuitive to perform as well as more efficient, so all users, even those new to SEM, can obtain comprehensive data.

The evolution of additive manufacturing (AM) over the last decade has been impressive and looks to be revolutionary as a disruptive technique in the overall manufacturing arena. However, there are still a number of obstacles to overcome concerning the quality of the final part. Micro Computed tomography (micro-CT) is a non-destructive technique used to create highly detailed 3D volumes of intact samples and is widely used throughout an AM part’s lifecycle, including process development, process monitoring, and final part quality. TESCAN micro-CT products meet this challenge head-on; providing maximum flexibility and versatility, as well as opening up the possibility to perform 4D studies on samples.

In this seminar we will provide the basics of micro-CT, examples of imaging 3D printed samples, and discuss the future of micro-CT, and dynamic CT – where samples are continuously scanned at high rates while undergoing change, either naturally or induced. If you’d like to learn more about this exciting topic, please join us to see the possibilities that micro-CT brings to the additive manufacturing space!

Improvements in performance and decreases in power consumption have long been the basic requirements in the design of electronic devices. These properties have been achieved through miniaturization of device building blocks (transistors, memory cells, etc.), reduction of the signal path (advanced integration of multiple components in one package), and optimization of other components, including displays, RF, MEMS, or batteries.

Developing new technology products is very challenging. Fast failure analysis (FA) significantly helps in determining defect root-cause and providing feedback to maintain feasible time-to-market and device reliability. FA in packaging, advanced packaging, displays, RF, MEMS, and batteries usually involves searching for a defect buried a few hundred micrometers or even millimeters under the surface. Due to the sensitivity of the structures, site-specific analysis of the defect is usually done in cross section and large amounts of material must be sputtered to get to the region of interest. Industry-proven plasma FIB technology has served these purposes for nearly 10 years. Recently, however, significant increases to both the complexity of the devices and the depth of buried defects, together with pressure on time-to-result have challenged even plasma FIB capabilities. Adding the thousands-times faster laser ablation technique to the plasma FIB sample analysis workflow speeds the time to premium results while also opening new synergies among other instrumentation in the FA laboratory. 

This webinar will provide you with an introduction to the TESCAN Large Volume Workflow. The flexibility of the workflow will be demonstrated using demanding samples of different sizes, including complex devices and non-conductive hard materials. We will show how to achieve fast, artifact-free sample preparation results that are compatible with UHR SEM imaging for revealing the finest details.

In November 2020, TESCAN announced the release of the new generation of TESCAN TIMA, a dedicated solution for automated mineralogical analysis in Earth Science studies as well as for industrial mineral processing. TIMA contributes to a wide array of applications ranging from petrography, metallurgy, liberation analysis, and provenance studies, even outside of geoscience.

TIMA is a user-friendly solution for executing petrographic workflows such as mineral identification and quantification, as well as localization of petrogenetically significant phases or their pairs based on their textural relationships, morphology, or association. TIMA can be the first step in complex analytical workflows followed by EPMA or LA ICPMS studies. TIMA is can be configured with an integrated Raman spectrometer, allowing direct identification of polymorphic modifications without the need to transfer the samples to other instruments. In addition to these features, TIMA also can provide a quantitative composition of both the individual mineral grains in relation to their morphology, as well as bulk composition of the entire sample.

In this webinar, we will focus on applications in geosciences and show how TIMA’s features and workflows support accurate, automated mineralogical analysis.

We are excited to present you our TESCAN brand-new solution in our Life Sciences product family, Serial Block-Face Imaging (SBFI).

Serial Block-Face Imaging (also known as Serial Block-Face SEM) is a traditional technique for high-resolution structural analysis of the sample using an integrated microtome to the SEM chamber. The method uses a diamond knife of the microtome to cut a slice from the sample surface (20-100 nm thin) which is immediately imaged by SEM. This process is repeated to create an image stack allowing a reconstruction of the sample volume.

In-chamber microtome device, compact size, simple and fast installation/de-installation, SEM / FIB-SEM GM chamber compatibility, effective LE-BSE imaging, and/or TESCAN volume analysis software – these are the key features that give us the opportunity to extend the capabilities of standard SEM to the volume scale of structural analysis. Key technical features of this exciting solution together with multiple application examples will be presented at the seminar.

The success of transmission electron microscopy (TEM) analysis depends heavily on the quality of the sample preparation. And sample preparation requirements become more stringent when the atomic resolution is needed or when material features are smaller or more complex. Using FIB to prepare samples for TEM provides the best method for achieving the required thin lamella and ensuring uniform quality. Today’s novel materials, in particular, require more advanced TEM sample preparation methods to truly observe the samples with the desired detail.

For these novel materials, sample thickness is not the only parameter that must be considered. FIB-SEM instruments allow site-specific sample preparation by combining several techniques that help to locate the feature of interest on the sample or determine the orientation of a structure. In some cases, the samples will require that the lamella is prepared from a specific geometry, which necessitates the use of a lift-out technique.

In this webinar, you will learn how the unique position of nano manipulator in the FIB/SEM chamber supports innovative lift-out methods and unique geometries that are opening new possibilities for TEM lamella preparation as well as new opportunities for more advanced studies.

With the similarities in today’s UHR-SEM resolution performance specifications, the criteria for evaluating UHR-SEM capabilities, slowly but surely, are placing more emphasis on the ability to use multiple diverse contrast methods to reveal information that is not visible with resolution alone.

In general, when energy is transferred to the specimen by the primary beam, the sample generates a range of useful signals that are exploited to characterize the material. One of the principal signals generated by the sample, the backscattered electron (BSE) signal, originates at a range of angles and emitted energies from different depths below the sample’s surface. Thus, the angular and energy-selectivity characteristics of the BSE signal are considered secondary backscattered electron contrast methods. It is evident that having the ability to acquire the BSE signal selectively brings with it the potential to enhance the information that a backscattered electron image reveals.

In this webinar, we will show how TESCAN CLARA UHR-SEM is tackling the requirement for differentiated contrast methods by implementing a comprehensive choice of backscattered electron detectors, including chamber-mounted segmented solid-state or scintillator backscattered electron detectors, an on-axis in-column detector, and the proprietary in-column Multidetector™.

Current trends in electron microscopy include increased focus on the analysis of beam-sensitive biological materials such as tissue or cell cultures. Modern SEM column designs are able to acquire images at very low accelerating energies which are key for efficient visualization of these sensitive biological samples at scales approaching the nanometer range.

Combining scanning electron microscopy with the site-specific milling capability of the focused ion beam (FIB) opens a broader range of possibilities for studying biological samples. FIB-SEM systems are widely used not only for routine preparation of ultra-thin specimens for analysis in the transmission electron microscope (TEM) but also for precise cross-sectioning and 3D volume imaging in both ambient temperatures and cryogenic conditions. FIB milling is used extensively to reveal sub-surface information from bulk material or to create samples for other analytical modalities. Using FIB-SEM for 3D tomography is a powerful technique in structural biology for enabling visualization of diverse organelles and tiny structures which helps researchers answer questions about the principles of biological processes.

In the seminar, we will discuss the capabilities of FIB-SEM solutions for detailed structural analysis of biological samples, including recent trends for using plasma-based FIB-SEM solutions to revealing the highest details in large volume sample analyses.

Presented by Lukas Hladik, Product Manager for FIB-SEM systems in the Semiconductor market segment

The global integrated circuit (IC) industry is facing not only continuous growth in demand for electronic devices but also improvements to device performance and energy consumption—all while decreasing device footprint. In order to achieve this, TEM lamella preparation has become an inevitable part of the failure analysis process.

The 3D structure of today’s devices requires the localization of defects in different projections. The shrinking device size dictates the need to use inverted TEM lamella geometry to achieve sub-10 nm lamella thickness.  With defect size now at the nm-scale, there is an additional need for plan-view TEM lamella geometry for STEM observation. Thus, TEM lamella lift-out procedures might require multiple manipulation steps or even breaking the vacuum to reach inverted or plan-view lamella geometries. TESCAN SOLARIS addresses these challenges with a patented setup that enables lamella transfer from a bulk sample onto a TEM grid with a single, simple manipulation step, and no need to break the vacuum or unload the sample. Most importantly, this approach does not require any additional hardware to be installed.

This webinar will provide you with insight into how TESCAN SOLARIS and its ecosystem can be utilized for semi-automated, high-quality, low beam damage sample preparation in the semiconductor FA lab environment.

Low-temperature electron microscopy (cryo-EM) has become an established technique for capturing and observing beam-sensitive samples in their close-to-natural state. 

Cryo-sectioning is a standard method used for thinning and slicing such samples. However, the integrity of the specimens can be degraded easily by common artifacts such as knife marks, compression, or crevasses.  Focused ion beam (FIB), on the other hand, is used extensively to reveal sub-surface information from bulk material, create samples for other analytical modalities, or prepare ultra-thin specimens for analysis in transmission electron microscopy (TEM), without knife-sectioning artifacts. 

Moreover, combining the site-specific milling capabilities of FIB with scanning electron microscopy (SEM) opens a broad range of possibilities for preparing biological samples. FIB-SEM systems are widely used not only for routine preparation of ultra-thin TEM specimens but also for precision cross-sectioning and 3D volume imaging, which are possible in ambient temperatures as well as in cryogenic conditions. 

The seminar aims to demonstrate the feasibility and discuss the potential of TESCAN cryo-FIB-SEM as a reliable tool for cryo-TEM sample preparation, with its exceptional range of additional capabilities—all within a single versatile workstation.
