Consumer demand is driving the electronics market to produce faster, smaller, cheaper, more power efficient portable devices. Device manufacturers must place a high premium on both time-to-market and device performance . On an operational level, this means working with shrinking geometries, new materials and novel architectures. At this level of innovation, critical dimensions are simply too small to see or characterize with existing tools. New, high productivity, increasingly TEM-centric workflows are required to perform this work.
Semiconductor device manufacturers and designers are pushing the boundaries of physics. Devices are being engineered at the atomic level. The number of technology options under investigation is increasing as the probability of technical and commercial success of any of them is becoming less and less certain. Thermo Fisher Scientific provides the most advanced toolsets that enable this advanced R&D to continue on the 10, 7 and even the sub 7nm technology nodes.
Time to market is becoming crucial for the commercial success of mobile electronic devices. Time to yield is critical to generate the required return on investment and commercial success of each product. Yield analysis at many of the steps in the manufacture of a semiconductor device used to be monitored by visual or SEM based tool sets, but these are now increasingly dependent on feedback and metrology from TEM images. Thermo Fisher Scientific is enabling this transition from SEM to TEM with new high productivity tool workflows which provide the lowest possible cost per TEM sample.
Producers of components for the consumer microelectronics industry face increasingly challenging processes which require very precise and repeatable yield control. Thermo Fisher Scientific produces dedicated workflow solutions which enable high performance yield characterization for the data storage and semiconductor markets.
Shrinking technologies, new materials, and more complex structures are driving defectivity, especially where the circuit design is particularly sensitive to process variation. These non-visual defects reveal themselves as electrical faults that downgrade device performance, threaten reliability, and destroy yield. The problem becomes even more complex when failures occur at the device packaging stage. High-density interconnects, wafer-level stacking, flexible electronics, and integral substrates mean that failure-inducing defects have more places to hide-making characterization more difficult, and more critical, than ever.

Mineralogy and ore texture are increasingly critical attributes that affect the ability of mining companies to extract base and precious elements from ores both economically and sustainably. A thorough understanding of ore mineralogy and texture will continue to play an increasingly important role, from upstream ore characterization, metallurgical testing and flow sheet design, to mineral processing. Textural properties of ores typically feature microscopic, sometimes nanoscopic, attributes; hence ore characterization, metallurgical testing and mineral processing are prime use cases for Thermo Fisher Scientific's mining imaging solutions.
Geoscientists have been examining and describing rocks for over 150 years, ever since the advent of light microscopes and petrographic thin-sections in the 1850's. The goal today remains much the same. By making detailed observations of a rock's mineralogy and microstructure, it is possible to unravel its history. However, with the advent of advanced geochemical methodologies becoming more mainstream in petrological studies (such as isotopic and trace element analysis ), the power of petrography to reveal features of interest is often overlooked. Furthermore, learning to identify minerals optically takes time and considerable practice. However, with our automated mineralogy solutions, geoscientsists can now efficiently, objectively, and quantitatively map materials.
