What’s at stake?
Fully depleted silicon-on-insulator solves the problem of leakage for chip makers, but the technology lags behind more-traditional FinFET processes. Now, the EU is banking on a new spin of FD-SOI as its ticket to sophisticated, next-generation ICs.

This is great stuff. Let’s get started.
