  • Maybe. Some of the older fabrication is still in heavy production use (e.g. 28nm, 16nm, 7nm):

    These produce a lot of the chips that go into everything electronic, things like bus controllers and timing ICs, which are needed in higher volumes than CPUs and GPUs. But I kind of doubt the older fab technology will be a priority to build in the new facility.

    TSMC isn’t just a single factory production line that gets upgraded to the latest and greatest every year. It’s a collection of many fabrication technologies that has grown and developed organically over time. While it will be helpful to build a new facility with the benefit of lessons learned in Taiwan, it will not be possible to completely replicate what that original facility is.
