The 2nm Semiconductor Node: A New Battleground in 2026

The semiconductor industry is entering a pivotal phase with the rollout of 2nm-class process technologies in 2026, which has started in mid 2025. This node, featuring gate-all-around (GAA) nanosheet transistors, promises significant gains in performance (up to 15% higher) and power efficiency (up to 30% lower) compared to 3nm predecessors. Leading foundries: TSMC, Samsung, and Intel are competing fiercely, while Japan's Rapidus aims to join by 2027. TSMC dominates with fully booked capacity, while rivals focus initially on internal needs or seek external customers through competitive pricing and yields.
