Intel, TSMC, and Samsung are all major players in the microprocessor chip industry. According to their official data, TSMC’s 3nm (FinFET) process technology is planned for commercial mass production in the second half of 2022 1. Samsung’s first 3-nanometer has been successfully developed and was in production in the second quarter of 2022 1. Intel’s 3nm-class node (Intel 3) is on track for high-volume manufacturing (HVM) in the second half of 2023 2.

As for a comparison between US, South Korean, and Japanese microchip industries, I couldn’t find any specific information on that topic. Would you like me to look up something else?
