核心零部件超过10万个，来自全球5000多家供应商。最关键的极紫外光源需要将锡滴加热到30万摄氏度，产生波长仅13.5纳米的极紫外光。反射镜表面粗 糙度要求小于0.1纳米，相当于把整个北京市的面积摊平后，高低差不能超过一根头发丝的直径。 半导体和稀土，这两个看似不相干的领域，正在上演一场惊心动魄的全球科技竞赛。中国突破EUV光刻机技术和美国重建稀土全产业链，哪个目标会先 实现？这场竞赛的结果，可能重塑未来几十年的全球科技格局。 中国EUV光刻机的突围之路有多难？ 光刻机被誉为"半导体工业皇冠上的明珠"，而EUV光刻机更是这颗明珠中最耀眼的部分。荷兰ASML公司垄断全球EUV市场多年，一台机器售价超过1.5亿 美元，比一架波音787客机还贵。中国要造出自己的EUV，难度堪比在芯片上建造一座微型城市。 但中国并非从零开始。上海微电子已量产90nm光刻机，28nm光刻机也取得突破。清华大学团队研发的SSMB-EUV光源方案，可能成为弯道超车的关键。 中国特色的举国体制在集中资源攻关方面具有独特优势，就像当年突破原子弹技术一样。 美国稀土产业链重建的挑战有多大？ 稀土不是土，而是17种金属元素的统称。从智能手机到电动 ...
