ThermoFisher Helios G4 UX Plasma Focused Ion Beam/Field Emission Scanning Electron Microscope

Instrument types

The Helios Plasma Focused Ion Beam (PFIB) Workstation is a fully digital, Extreme High Resolution (XHR) Field Emission Scanning Electron Microscope (FE SEM) equipped with inductively coupled plasma (ICP) focused ion beam (PFIB). It allows in-situ large area sample preparation and high resolution imaging and analysis of
hundreds of microns areas. Site specific, high volume material removal for top down deprocessing, x-sectioning, Chunking and TEM preparation on individual die and/or packaged parts in a laboratory environment. The key enabling technologies are all integrated onto a single platform such as:

  • XHR electron optics (magnetic immersion lens type) with electrostatic scanning,and advanced SE detection
  • An ultra-high brightness NG electron source
  • Electron Beam Deceleration for improved low energy performance, access to ultra-low landing energies (down to 20 eV) and balanced topographic and material contrasts.
  • An optional high-sensitivity, retractable solid-state backscattered detector (DBS)
  • Complete suite of standard high-sensitivity detectors for superior detection of SE and BSE signals even at low landing energies, with the ability to acquire simultaneous SE and BSE images.
  • ConstantPower™ design of electromagnetic lenses for ultimate stability, high controllability and reproducibility of the electron beam
  • PFIB Ion Column for outstanding performance in high volume material removal and precision milling
  • Integrated control of the MultiChem Gas Delivery System to deliver precise, repeatable doses to the sample as well as mix gas precursors prior to injection. At least one metal deposition precursor must be selected with up to an additional five selectable precursors optionally available, including up to two external gases.
  • A high-precision, 5-axes eucentric specimen stage with 150 mm travel along the x and y axes.
  • An integrated beam current measurement
  • A high-resolution, 16-bit digital patterning engine capable of Simultaneous Pattern and Imaging (SPI™)
  • An integrated Real Time Monitor (iRTM)
  • Selective Etch Software to enable contrast selective milling
  • A system architecture which is optimized for automation to support consistent EFI sample preparation or Slice and View applications
  • Optional iFast™ Academic Science automation package enables engineers to quickly and easily create new recipes or modify existing recipes for use with the iFast Runner
  • Designed for SEMI S2 and CE compliance
  • Windows User Interface optimized for three 24” widescreen LCD monitors, allowing for up to four independent live images and a large image window
  • Manual user interface and joystick for fast and intuitive microscope control
The instrument is also equipped with the TEAM EDS system:

The TEAM™ Software Suite, coupled with the Octane Elect and Octane Elite Energy Dispersive Spectroscopy (EDS) Systems is the most intuitive and easy to use analytical tool available for the SEM.  The workflow functions are automated by integrating years of EDAX knowledge and expertise to work for you. Startup, Analysis, and Reporting are easy because the TEAM™ software automates each task. It is the only EDS technology that combines smart decision making and guidance for the novice with advanced features for the experienced user. Now you have the intelligence of an EDS expert every step of the way.

Smart features, exceptional results

The TEAM™ Software Suite for the SEM was designed to save time and ensure accurate, reproducible results for a wide range of applications. Whether simply collecting a spectrum or performing complex phase analysis, the system and its touch screen capability make it easy to quickly get the results you want. The software is built with a modern interface optimized for running in multicore and multiprocessor environments. Our TEAM™ Software Suite offers Smart Features for startup, analysis, and reporting not found in any other system. The core components that make up this functionality include:


Smart Track’s environmental panel monitors system status; reports operating conditions for the detector, stage, column, and more; plus allows access to advanced controls. Smart Acquisition automates routine tasks for ease of use and times savings.


Smart Phase Mapping provides a higher level of analysis by automatically collecting spectra and generating phase maps with elemental distribution and associated spectra. Point analysis and line scan with next-generation EXpert ID enable fast and easy measurement of individual and multiple points from selected areas.
