The facts are tsmc won't have volume production of 20nm until middle of 2014
and will not have 16nm finFET in volume production until 2016 at the earliest. If you don't believe me, go listen to TSMC's last two earnings conference call. The other fact is tape-out is not the same as volume production. We say announcement of 20nm tape out way back in 2010/2011 and there is no sign of it now, 3 years later. This semiwiki is an obvious short and spreading misinformation.
