The frontier前沿概述

Modern civilization sits on a stack: AI on chips on photolithography on quantum mechanics. Every order of magnitude humans gain in computing comes from learning to herd electrons across smaller and smaller silicon landscapes. Today the leading edge writes structures three nanometres across with extreme ultraviolet light bouncing off the surface of a vaporized tin droplet. Each generation gets harder, and each is more important than the last because everything else — AI, biology, finance, governance — feeds on it.现代文明立于一座叠层之上：AI 之上是芯片，芯片之上是光刻，光刻之上是量子力学。人类在算力上每提升一个数量级，靠的都是把电子驱赶到更小的硅地形上。今天前沿的工艺，是用极紫外光——经由蒸发的锡液滴反射而来——在三纳米的尺度上书写结构。每一代都更难，但也更重要，因为其他所有领域——AI、生物、金融、治理——都以它为食。

Historical evolution历史演化

1947
Transistor晶体管
Bardeen, Brattain, Shockley invent the switch that makes everything else possible.巴丁、布拉顿、肖克利发明了让其他一切成为可能的开关。
1958–59
Integrated circuit集成电路
Kilby and Noyce independently put multiple transistors on a single substrate.基尔比与诺伊斯各自把多枚晶体管放上单一衬底。
1965
Moore's Law摩尔定律
Gordon Moore predicts transistor density will double every ~2 years. It does, for 60.戈登·摩尔预测晶体管密度每约两年翻一倍——这一规律持续了 60 年。
2017–
EUV in productionEUV 进入量产
ASML's extreme ultraviolet tools enable 7nm and below.ASML 的极紫外设备让 7nm 及以下成为现实。
2024
2nm + GAA2nm 与 GAA
TSMC and Samsung move to gate-all-around transistors at 2nm.台积电与三星迈向 2nm 全环绕栅极晶体管。

State of the art今日状态

Three players are at the leading edge — TSMC, Samsung, Intel. Five tools companies — ASML, Lam, Applied, Tokyo Electron, KLA — gate the entire industry. The geopolitical surface has become as important as the technical one: chips are now a strategic resource on the order of oil. AI demand has tipped the industry into a structural shortage of leading-edge capacity.前沿玩家三家——台积电、三星、英特尔；五家设备商——ASML、Lam、Applied、东京电子、KLA——把守住整个行业。地缘政治面与技术面同样重要：芯片，已成为可与石油相比的战略资源。AI 的需求把行业推入前沿产能的结构性短缺。
