TSMC is currently delving into the possibility of collaborating on the Terafab project, which is a joint investment venture between SpaceX and Tesla. TSMC views this project as a significant potential customer for its upcoming wafer fabrication plant in Texas. In response to this development, Musk stated that discussions are still ongoing, but there is potential for further progress. It's worth noting that Terafab has already secured a cooperation agreement with Intel in the past.
