EUROPRACTICE adds CORNERSTONE SOI process to its Photonic technology portfolio through Tyndall National Institute and University of Southampton

Cork (Ireland) – July 7, 2020 – Tyndall National Institute announces that a new set of Silicon-on-Insulator (SOI) process services by CORNERSTONE, an open source Multi-Project Wafer (MPW) foundry, is now available to EUROPRACTICE customers.


EUROPRACTICE MPW service, through Tyndall National Institute, will now offer license free, open source Silicon Photonics rapid prototyping processes from CORNERSTONE for three different silicon-on-insulator platforms.


The CORNERSTONE prototyping platform utilises industrially-compatible deep-UV projection lithography to enable seamless scaling-up to production volumes via your favourite commercial foundry, but also retains device level innovation capability and flexibility in its process flows, making it ideal for researchers to try innovative designs, or to evaluate new Photonic circuits.


Callum Littlejohns, PhD., CORNERSTONE coordinator comments:


“We are delighted to be able to offer our flexible, open source SOI platforms to EUROPRACTICE customers who can now benefit from the wealth of experience and expertise within our team, at extremely  affordable prices. We pride ourselves on our friendly and personal service and are pleased that EUROPRACTICE customers can now exploit this.”


“At EUROPRACTICE, we are very glad to see that our Photonic technology portfolio keeps on expanding rapidly. We are particularly happy to include CORNERSTONE in our offer because of its unique SOI technology, and the fact that it is open source means it will attract previously unreached researchers, scientists, engineers and innovators. I can’t wait to see the technology that will come out of this!” adds Dr. Ramsey Selim, Board Member of EUROPRACTICE and Photonic Programme Manager at Tyndall National Institute.



CORNERSTONE is a collaboration between the University of Southampton and the University of Glasgow in the UK, specialising in the fabrication of silicon photonics devices using both DUV and e-beam lithography. Led by Professor Graham Reed, members of the CORNERSTONE team have pioneered silicon photonics since the late 1980s, and have a track record of world leading results, particularly in the field of carrier based modulators.
