At the 2022 Technology Symposium, TSMC unveiled five nodes that will begin production in the three years from 2022. The image below is the state-of-the-art technology portfolio presented by TSMC at the symposium. Semiconductors manufactured by the 3nm process have a total of five nodes, 'N3' and its derivatives 'N3E', 'N3P', 'N3S', and 'N3X'. Will start.

Due to the complexity of the manufacturing process, the time required for research and development has increased, making it difficult for semiconductor foundries to announce completely new nodes every two years. However, TSMC will respond to customer needs for improved performance per power consumption and transistor density every year by offering an expanded version of the N3 node.
In addition, since the manufacturing of N2 nodes depends on a new technology called 'gate all-around field effect transistor (GAA FET)' using nanosheets, it is expected that the manufacturing cost will increase and the design method will change. Many customers other than developers seeking cutting-edge chips will continue to adopt N3 for more than a few years after the introduction of N2, so in anticipation of these demands, TSMC has prepared multiple nodes for N3, technology media Anand Tech said.
The N3 node manufactured by the 3nm process consumes 25 to 30% less power than the N5 node, and the performance at the same power is increased by 10 to 15%. It is reported that the N3 node has already entered mass production, and delivery to customers is expected to begin in early 2023.
In addition, this is a comparison of the performance of the N3E node and N2 node, which are expanded versions of the N3 node, with a graph with total power consumption (Total Power) on the vertical axis and Speed (calculation speed) on the horizontal axis. N2 nodes consume 25-30% less power and perform 10-15% better than N3E nodes. However, it is said that the transistor density is improved by only about 10% compared to N3E, and the difference seems to be even smaller when compared with the N3S node optimized for transistor density.

TSMC plans to start mass production of N2-node semiconductors in the second half of 2025, and is expected to hit the market in the second half of 2025 to 2026.
