All indications point to TSMC's N2 process node being a beautiful one. TSMC recently discussed their 2nm process node at IEDM 2024, calling it the "world’s most advanced logic technology". N2’s headlining feature is of course the Gate-All-Around transistor. Its first major transistor transition in nearly 15 years. But there is another new technology being inserted into the node: The Curvilinear mask, or masks with curved lines. TSMC's first node with curvy masks. Curves. Big whoop, right? It matters because these masks unlock the power of GPUs for semiconductor manufacturing. In this video, TSMC’s curvy masks for its 2nm node.
