DNWL: I believe a separate testing device has to be created for wafer testing and presumably this is done in the UCONN lab facility.

Agreed, David.

Remember that we wondered why the ring oscillator isn't done in the superior 40 nm structure size but in 100 nm instead? Now we know the answer: 100 nm can be done in the POET/UConn lab without any "3rd party foundry", and obviously it can be done with the old sputter tool. Yes, they already had a sputter tool since the new one is "additional", according to the news release as of 2015-01-08.
