FIB sampling service for Materials Scientists (Academic and Industrial)

NanoScope Services offers 3 high-end FIB sampling services for sample preparation and Analysis.

NanoScopes’s Focused Ion Beam (FIB) sampling service provides many possibilities for preparing sections not possible using more conventional mechanical polishing or sectioning methods. We work with clients across the UK, Europe and Middle East time zones.

Ion Beam imaging may be done with secondary electrons or ions and offers greater materials contrast than SEM imaging. Unlike electrons, the information comes from the top few nm’s of the sample, and resolutions are comparable at 5nm’s or less.

For a detailed description of the equipment and techniques available, go to the Tools and Techniques page.

FIB prepared Micro Cross-sections with SE/SI imaging.

A FIB microscope can precisely locate and section any feature on a sample and directly take images of it. Multiple slices (even with different orientations) can be taken through the same feature to provide 3D information.

There are 4 clear advantages

  1. It is ECONOMICAL, EASY and FAST. Preparing a conventional mechanical section through a complex material takes time. FIB is efficient, versatile and cost effective, with samples processed quickly and the images emailed directly to you.
  2. EXACT LOCATION and ORIENTATION – a FIB micro section may be prepared at a very precise location on the specimen surface. This can be through a specific feature or failure, interface or particle, even a crack or void. The orientation of the section may also be defined. Multiple sections may be taken through the same feature or in very close proximity, with each one being uniquely positioned and orientated as desired.
  3. MATERIALS INDEPENDENT – The FIB process is largely independent of materials hardness or structure. Softer materials do not smear, harder materials are polished at similar rates to softer ones, and interfaces are preserved.
  4. MINIMAL MECHANICAL PREPARATION is required for FIB processing. If the sample is small enough to be loaded and is clean and vacuum compatible it can be sectioned.

FIB Prepared ‘Ultra thin’ TEM sections.

This tried and tested process has been used routinely for many years and successfully applied by NanoScope to prepare customers samples from over 200 materials systems.

There are 4 clear advantages

  1. EXACT LOCATION and ORIENTATION – Have your ‘ultra thin’ section prepared from exactly where you would like. Specify the orientation of each section as well.
  2. MATERIALS INDEPENDENT – The FIB milling process is largely independent of materials hardness or structure. Complex materials combinations and devices are possible to prepare within a single section.
  3. ‘LARGE’ IMAGING AREA – A FIB prepared section tends to be of uniform imaging thickness and quality, allowing information to be collected across the majority of the section area.
  4. MINIMAL MECHANICAL PREPARATION. Most samples are immediately acceptable for FIB processing without embedding and slicing or cleaving and grinding. If it is clean and small enough, vacuum compatible and has a flat(ish) top surface it can probably be loaded immediately.

TEM Analysis of FIB prepared sections

A variety of TEM instruments may be used for your high end imaging and analysis requirements.

Select the analytical TEM techniques you require from this list of capabilities:-

  1. Bright/Dark field imaging with referenced metrology as required.
  2. Diffraction patterns taken from your specified points.
  3. Elemental Analysis either as points, linescans or maps to identify which materials are present and their locations.
