Hitachi High-Technologies Introduces the Ultimate Field Emission Scanning Electron Microscope: The SU8200 Series

-Innovative Cold Field Emission Gun with Unmatched Resolution and Beam Stability-

Hitachi High-Technologies Corporation (TOKYO: 8036, Hitachi High-Tech) announces the development and worldwide release of the new SU8200 series Field Emission-Scanning Electron Microscopes (FE-SEMs) employing a novel cold field emission (CFE) gun for improved imaging and analytical performance. The newly designed Hitachi CFE gun complements the inherent high resolution and brightness of conventional CFE with increased probe current and beam stability. The best SEM source gets even better.

SEMs are utilized in a broad range of scientific fields and applications including nanotechnology, semiconductors/electronics, materials science, biotechnology, and pharmaceuticals. The latest trends in advanced materials research are migrating towards carbon and polymer materials used in lithium-ion batteries, fuel cells, and catalysts in support of efficient technologies for future generations. Characterizing these modern materials requires extended SEM capabilities beyond pure resolution. Quality imaging at low acceleration voltage (Vacc) is critical to mitigate beam damage, and highly sensitive elemental analysis is required.

The heart of the new SU8200 series is the innovative CFE source. This novel CFE gun employs a Hitachi patented "Mild flashing" technique and a new vacuum system which greatly minimizes gas molecule deposition on the emitter tip. The emitter always operates in a "clean" state, and emission current and beam stability are significantly improved. The result is the ultimate SEM electron source offering high S/N, stability, and uncompromising resolution performance at low acceleration voltages. Further, these enhanced performance capabilities open a new gateway for low voltage elemental microanalysis. The SU8200 series supports a variety of large-diameter silicon drift detectors (SDDs) for high spatial resolution, high sensitivity, and high speed X-ray detection.


Ultra high resolution FE-SEM SU8240

SU8200 system features include a new top detector filtering system for enhanced electron detection specificity. Fine contrast differentiation is now achieved by selectively filtering inelastic scattering electrons and directly detecting specific energy back scattered electrons. This selective filtering is particularly powerful for enhancing material contrast at low acceleration voltages. Vibration control measures for the stage and chamber, and optimization of the optical system contribute to the high resolution system performance of 0.8 nm at 15 kV and 1.1nm at 1kV. The SU8200 series includes three models (SU8220, SU8230, and SU8240) offering various stage, chamber, and detector configurations for a wide range of applications.

Hitachi High-Tech will conduct a poster panel exhibit of the SU8200 series at the 69th Annual Meeting of the Japanese Society of Microscopy to be held in Suita City, Osaka May 20-22, 2013.
