The ~$380M next step: bigger optics, finer features, halved field size.
您正在查看一条技术记录：AI 硬件的一个基础构件——它的功能、谁来制造，以及哪些芯片和系统使用它。
High-numerical-aperture EUV (0.55 NA) resolves ~8 nm features in one exposure. Intel took the first production tools for its 14A roadmap; TSMC adopts more cautiously. Each system ships in multiple aircraft and costs around $380M — the most complex machine ever sold.
