This tool is next-generation compared to our present three about 10 years old Supra-40/60 SEM’s (also from Carl Zeiss). We are looking forward to offer our users access to all the new features provided by this tool, a.o.:
- SE2: Chamber mounted secondary electron (SE) detector
- In-lens SE: In-column high resolution SE detector
- In-lens EsB: In-column highly sensitive backscatter electron (BSE) detector for obtaining good material contrast
- aBSD: Retractable column mounted solid state BSE detector with six sectors for detection of energy and angle selective backscattered electrons, i.e. for obtaining both material and topographical contrast
- VPSE: Variable pressure (VP) light detector for SE signal detecting
- aSTEM: Retractable solid state STEM detector with five sectors enabling bright field and both annular and oriented dark-field transmission electron imaging
Furthermore, this tool will provide dramatically improved performance on insulating samples achieved via two pathways:
- Latest generation column design that takes low kV imaging to the next level
- Sophisticated low vacuum modes for charge compensation:
- Standard variable pressure (VP)
- NanoVP: A retractable differential pumping aperture mounted on the column makes it possible to use the In-lens SE and ESB detectors in VP mode
Other features:
- Installed on an actively damped anti-vibration platform and with magnetic field cancellation system to protect it from external sources of noise
- Sample bias option and dedicated samples holder
- Plasma cleaner for in-situ sample and chamber cleaning
- Sample loading trough a load lock or the chamber door
- Load lock mounted camera for easy sample navigation
- Several new automated features
We will spend the coming weeks on the installation and acceptance tests of the tool and prepare the training protocol. We hope, that you will be as excited as we are when we release it in September (expected release).
