General Benefits

The imaging, analysis and control of matter at the nanometer scale are key factors in successfully conducting research today. Resolution, accuracy, reproducibility, robustness and flexibility are key characteristics for a leading-edge tool.

Following three generations of success in electron microscopy, GAIA3 is the next generation platform introduced by TESCAN. Combining unsurpassed nanometer resolution SEM performance with excellent COBRA-FIB capabilities, the new TESCAN GAIA3 offers a wide range of analytical compatibilities.

The greatest benefits of the GAIA3 is its low-voltage SEM imaging while maintaining a high resolution. This is essential especially for examining sensitive or non-conductive samples with a small interaction volume therefore giving excellent resolution and unique low voltage contrast.

COBRA-FIB is a top-level technology in terms of resolution for both imaging and milling. It is the sharpest FIB instrument for nano-engineering in its class.

GAIA Software suite and automated operations

TESCAN´s well-known user-friendly software, many automated procedures, remote access and scripting libraries enables all users to achieve exceptional results.  Furthermore GAIA3 is able to offer experienced users access to detailed and expert system settings to maximise the customization of the observation settings. Multi-user localized environment, modular software architecture, network operations and wide range of extensions turn GAIA3 into most versatile instrument available.

Automatic set-up of the microscope and many other automated operations are characteristic features of the equipment. Automatic procedures like In-Flight Beam Tracing™ optimization for both electron and ion beams, gun heating and centering, column centering, vacuum control, compensation for kV focusing, contrast & brightness, spot optimization, auto-diagnostics, setup of FIB-SEM intersection point, GIS nozzles positioning and temperature control, automated FIB as well as SEM emission start etc. reduce the operator´s tune-up time significantly.

Analytical potential of FIB/SEM analysis

The ever-increasing demands for sample throughput and precision of milled objects are met by integrating the most innovative focused ion beam technology. Galium ion sources with a unique design deliver an excellent imaging resolution combined with high-current and high-density ion beams. Thanks to innovated fast cross section milling approach, the milling speed is increased more than 2.5 times. The deposition of conducting or nonconducting materials, as well as enhanced and selective etching, can be performed with either the electron or ion beam when combined with the highly flexible gas injection technology. This enables the milling process to be carefully controlled. Moreover, by automatically combining several images, a complete 3D-model of the sample can be created.

Precision in sample modification

The ability to integrate analytical methods is much easier to achieve with the GAIA3. Combining a SEM and ultra-high-
resolution Cobra FIB column provides superior observation and modification experience. The 5-GIS system enables a
variety of techniques for micro- and nanofabrication that can be used for the deposition or etching of samples. Of course a wide range of precursors are provided that significantly expand the number of ways the method can be used. The instrument can be optimized for specific customer requirements using presets and an intuitive scripting language as well as extended with a wide range of TESCAN´s or 3rd-party detectors

High-performance COBRA-FIB

COBRA-FIB is an ultra-high resolution FIB column. In addition to its unsurpassed resolution guaranteed at 2.5 nm, sub-2 nm images have been performed with gallium at 1pA. High-current modes have also been optimized, providing an extremely well defined beam shape with unique milling performance.
