CORDE

@cordecavendish.bsky.social

Part of Cambridge's Cavendish Laboratory, CORDE enables university and industry researchers to access facilities and expertise unique to Cambridge.

What happens when you use general-purpose AI to help recommission a new microscope? Ke Wang & colleagues built and sandbox-tested a new control system for a CORDE Scanning Helium Microscope, then demonstrated it on real imaging and diffraction experiments. Read the paper: doi.org/10.1039/d6dd...

When materials are only atoms thick, even tiny contamination matters. New AFM paper from Cambridge researchers, with work carried out in part at CORDE, uses scanning helium microscopy to map sub-monolayer contamination on wafer-scale 2D MoS₂. 🔗 buff.ly/whrxZyX

Schematics of helium atom diffraction from crystalline surfaces under different levels of contamination. The scattering is a mixture of ordered Bragg scattering and disordered diffuse scattering.

High pressure helium gas is expanded into a vacuum and repeatedly collimated to produce a microscopic probe. The helium atoms scatter from the sample either in ordered manner (specular/diffraction) or disordered manner (diffuse). The atoms scattered in a specific direction are collected and detected. The sample is manipulated in x y to image and y z to perform diffraction scans. A specialized, heater compatible, SEM sample stub is used to control the sample temperature.

🎄Device fabrication doesn’t always have to be serious ✨ This festive season, we patterned silicon wafers with a Christmas design as a gift for our cleanroom team. Wishing you all a very Happy Christmas - filled with warmth, laughter, and unforgettable moments 🎄🎅🏻

CORDE  Nanofab Christmas

We will be taking a social media break over the festive period and will return in January. In the meantime, on behalf of everyone at CORDE, have a safe and peaceful festive season and a Happy New Year!

🔬 After coating the wafer with resist, it’s time to transfer the design into the photosensitive film. Here we see a resist-coated wafer being mounted and loaded into the VB6 Electron Beam Lithography tool ahead of the process.

From chip-scale experiments to wafer-level innovation💫 Our new Nanofabrication Cleanrooms at the Ray Dolby Centre are equipped to support it all. Here, a researcher runs a 200 mm wafer through the Oxford Instruments ICPCVD tool - used to deposit uniform, dielectric films onto wafers and chips.

New paper out: Surface visualisation of bacterial biofilms using neutral helium microscopy. Led by Royal Society Wolfson Visiting Fellow Prof. Paul Dastoor with the CORDE Characterisation team, this international collaboration used the UK’s only SHeM to image biofilms — no coating, no damage.
