In the company's latest annual report, TSMC reveals it's developing 2nm technology. At the same time, TSMC is also progressing in research for nodes beyond 2nm:
Faced with the increasingly difficult challenge to continue extending Moore’s Law, which calls for the doubling of semiconductor computing power every two years, TSMC has focused its R&D efforts on offering customers first-to-market, leading-edge technologies and design solutions that contribute to their product success. In 2019, following the transfer to manufacturing of the 7nm+ technology and the successful risk production of 5nm technology, the Company’s R&D organization continued to fuel the pipeline of technological innovation needed to maintain industry leadership. While TSMC’s 3nm technology, the sixth generation of technology platform to make use of 3D transistors, continues full development, the Company has initiated the development of 2nm technology, a pioneering effort within the semiconductor industry, and at the same time, is progressing in research and exploratory studies for nodes beyond 2nm.
