TSMC founder Morris Chang said today that the semiconductor giant and Apple supplier will build 3-nanometer chips at its factory in Arizona, though final plans are not ready yet. The factory is currently under construction, with plans to begin production in 2024.
During a press conference in Taipei, Chang said "three-nanometer, TSMC right now has a plan, but it has not been completely finalized," Reuters reports. "It has almost been finalized in the same Arizona site, phase two. Five-nanometer is phase one, 3-nanometer is phase two."
On its website, TSMC says its 3-nanometer tech, called N3, will be a full node stride from its 5-nanometer technology and will offer up to 70% logic density gain, up to 15% speed improvement at the same power, and up to 30% power reduction at the same speed when compared to its predecessor. It is targeting volume technology in the second half of this year.
