Please provide link then. I'm pretty sure they never said that.
I won't bother to find a link, but do you realize that the burden of proof is yours; TSMC replaced their planar with a FinFET transistor but kept the same BEOL, but then they realized they could do some optimizations to improve density by 15%, so they developed this slightly superior version of their 1st FinFET node. I clearly remember reading the quote from TSMC about it.
