TSMC discloses key indicators for the first time in 2nm process

TSMC held its 2021 technical seminar online today and announced the progress of the new process in the future. There is new news about 6nm, 5nm, 4nm, 3nm, and 2nm.

The 2nm process is currently the commanding height of the major semiconductor giants. IBM has even gotten it in the laboratory and first announced the 2nm chip. In addition to the two major foundry giants, TSMC and Samsung, Europe and Japan are also ambitiously planning.

Unlike previous generations that continue to evolve on the same infrastructure, TSMC’s 2nm process will be a truly brand new design. It is known as the biggest leap in history. The biggest feature is that it will introduce nanosheet transistors for the first time to replace the current FinFET structure.

TSMC stated that nanosheet transistors can better control the threshold voltage (Vt). In the semiconductor field, Vt is the minimum voltage required for circuit operation. Any slight fluctuations will significantly affect the chip design. TSMC claims that, based on experiments, nanosheet transistors can reduce Vt fluctuations by at least 15%.

At present, TSMC 2nm process has just entered the formal R&D stage. The previous news is that it will be trial production in 2023 and mass production in 2024.
