Taiwan Semiconductor Manufacturing Co. plans to begin production with its A14 fabrication process in 2028, aiming to remain at the cutting edge of the chip industry. The technology will advance the world’s biggest chipmaker beyond its current state-of-the-art 3-nanometer fabrication and the upcoming 2-nm later this year.

During its quarterly earnings, TSMC announced plans to make 30% of its best chips in Arizona. Here's when this might happen.
