因此，这些公司拿到 CCATS 之后推进台积电 7nm 生产，并不意味着美国"解禁"，只是表明它们 成功证明自己不属于被严格禁运的 3A090.a。美国的规则一条都没改，台积电也不是"被放行"， 只是严格按照规定办事：你给我官方分类认定，我就能在法律允许的范围内生产；你没有这个文 件，我一个字也不敢碰。 昨 天不少群都在刷一条劲爆消息，说美国突然"解禁"台积电 7nm，让几家中国 AI 芯片公司 重新拿到台积电的代工资格，还列出了几家公司的名字，看上去好像有重磅政策松动。但如 果你去把原始文件和流程细看一遍，就会发现这其实完全是个误读，美国没有松绑任何规 则，台积电也没有得到任何"特批"，真正发生的事情既不神秘，也不意外，只是几家公司拿 到了一个叫 CCATS 的东西。 要理解这件事，首先得知道 CCATS 到底是什么。很多人听到这个词，会以为它是出口许可，或 者某种豁免，其实完全不是。CCATS 的全名是 Commodity Classification，是美国商务部工业与安 全局（BIS）给企业的一种官方分类认定文件，作用非常简单：告诉你，"你的芯片到底属于哪个 ECCN 类别"。ECCN 是美国出口管制 ...

近日，荷兰《NRC》报道称，在上周的议会辩论中，议员们对政府经济事务部长文森特·卡雷曼斯（Vincent Karremans）处理安世半导体（Nexperia）事件的方式提出了相当多的批评。 虽然卡雷曼斯试图将自己塑造成捍卫国家安全的英雄，但国际舆论与荷兰政界对他粗糙的外交手腕并不买账。德国 《法兰克福汇报》极具讽刺意味地评论道，卡雷曼斯看起来像是"想用一把大锤来砸开一颗坚果"。 在荷兰议会内部，批评声同样尖锐。来自JA21党派的议员安娜贝尔·南宁加（Annabel Nanninga）直言不讳地斥责卡雷 曼斯的态度极其"粗鲁"。她指出，在没有任何双边外交铺垫的情况下就贸然对抗中国，这种做法是"彻头彻尾的不明 智/愚蠢"。 卡雷曼斯此次行动最荒谬之处，在于法律工具的选择与其后果的截然对立。报道指出，他引用了一部1952年的冷门战 争法，该法原本的设计初衷是为了"保护物资供应"。 然而，极具讽刺意味的是，正是因为他动用了这部"保护供应"的法律，直接导致中国切断了安世半导体中国工厂的出 口。 这一鲁莽举动不仅没有保护供应，反而让依赖这些芯片的德国汽车工业陷入停摆风险，甚至连冰箱等家电生产都受到 威胁。最终，在巨大的 ...
