Taiwan Semiconductor Manufacturing Company (TSMC) has announced that its chips manufactured on 3nm manufacturing process will appear in 2023, and those made with 2nm process will debut in 2025. At the TSMC 2022 Technology Symposium, the chipmaker also announced a new technology, FinFlex, that it will use to make the N3 and N3E chipsets. The technology would give manufacturers the versatility to provide high performance, lower power consumption and maximum transistor density based on three-blade configuration options.

According to the announcement at the symposium, the chipsets made by N3 technology, or the 3nm manufacturing process, will enter volume production later in 2022. The 3nm node will debut in five levels: N3, N3E (Enhanced), N3P (Performance Enhanced), N3S (Density Enhanced), and N3X (Ultra High Performance). The N3 chips use FinFlex architecture technology and are offered in three configuration options: 3-2 fin, 2-2 fin and 2-1 fin.

“Before TSMC N3 and FinFlex, chip designers often had to make difficult choices between speed, power consumption and chip density,” the company said. The new methodology is said to “enable full optimization of the N3 design library”, resulting in high performance, efficient computing and maximum transistor density.

The 3-2 fin configuration is for those who want the highest performance, the 2-2 fin configuration offers a balance of performance, energy efficiency and density. Finally, the 2-1 fin configuration is for those who want high power consumption and highest density.

Coming to N2 technology; the chipsets manufactured by the 2nm manufacturing process are expected to go into production in 2025. These SoCs will be even more powerful and efficient than the 3nm chipsets. According to the TSMC, 2nm chips offer a 10-15 percent speed improvement at the same power, or a 25-30 percent power reduction at the same speed. The technology will include a nanosheet transistor architecture “to deliver a complete improvement in performance and energy efficiency.” Production of N2 is planned for 2025.
