POET Technologies Inc.

From http://arstechnica.com/gadgets/2015/02/intel-forges-ahead-to-10nm-will-move-away-from-silicon-at-7nm/:

The most likely replacement for silicon is a III-V semiconductor such as indium gallium arsenide (InGaAs), though Intel hasn't provided any specific details yet.

So Intel is starting to move away from silicon! Will be interesting to see what they'll be presenting at ISSCC!

No details are known yet, but hopefully some POET patents will get into their way and they'll be forced to license IP!
