If you're referring to the 'Samsung Austin Semiconductor' in Tech Ridge, I wonder how well the fab is aging. The last building I remember was built primarily for NAND flash production back around 2007 ( https://phys.org/news/2007-06-samsung-largest-wafer-austin-t... ).

Though chipdesign and not fab, also worth remembering Apple acquired Austin-based Intrinsity in 2010 (https://en.wikipedia.org/wiki/Intrinsity)
