TSMC, Samsung and Intel will start mass production of 2nm process

TSMC, Samsung and Intel, the world's three largest wafer foundries, all plan to start mass production of 2nm process this year. According to market research firm TrendForce, TSMC is expected to take the lead in 2nm process. Although Samsung has introduced the gate-all-around (GAA) architecture on the 3nm process, the trial production yield of its 2nm Exynos 2600 processor is only about 30%. In contrast, although TSMC's 2nm process also uses the GAA architecture for the first time, its yield is twice that of Samsung. For Intel, its 18A process is ready for third-party customers and is expected to complete design trial production in the first half of 2025.
