- 美国官员取消了允许企业向华为和中芯国际出售先进芯片的许可。
- 这一决定是在华为使用7纳米芯片之后做出的，引发了对出口管制的担忧。
事件经过：华为新芯片发布后出口管制收紧
美国政府取消了出口许可。这些许可允许英特尔和高通等公司向华为技术有限公司出售先进芯片。此事发生在华为发布Mate 60 Pro手机之后。该手机采用了7纳米芯片。据称该芯片由中芯国际制造。这表明尽管受到美国限制，中国在芯片技术方面仍在取得进展。美国自2019年起已限制对中芯国际的销售。现在它阻止企业向华为和中芯国际两家公司输送技术和零部件。 另见: Ziggo集团任命领导人，备战2027年阿姆斯特丹上市.
美国商务部表示撤销许可是为了保护国家安全。受影响的公司直接收到了通知。部分已启动的销售可能仍会完成。由于担心中芯国际与中国军方有联系，特朗普政府在2020年将其列入限制名单。现在美国正在加强这些限制。目的是阻止中国在制造重要芯片方面取得进步。 另见: Alejandro Estua.

为何重要
这表明美国在与中国进行的科技战中更加强硬。华为的新7纳米芯片让人们担心原有的出口限制不够有效。该芯片采用深紫外光刻（DUV）这种较旧的设备制造，并未使用极紫外光刻（EUV）这一最新设备。这意味着中国仍面临问题，但仍能改进芯片制造。 另见: 亚历杭德罗·曼佐.
新规则可能改变大型芯片公司的业务方式。英特尔和高通可能会失去在中国的销售，中国对他们来说是一个非常重要的市场。因此，中国可能尝试自主制造更多芯片工具和材料。TechInsights的专家检查了华为的麒麟9000S芯片，表示其采用了7纳米技术。这表明即使面临美国制裁，中芯国际仍在进步。美国还在阻止阿斯麦等公司向中国出售芯片工具。这增加了更多压力。这是一项更大计划的一部分，旨在保护关键技术并减缓中国在半导体领域的进步。 另见: 亚历杭德罗·埃尔南德斯.
