当前,几乎所有从中国进口到美国的产品都已面临高额关税。根据富国银行经济部门和纽约联邦储备 银行分析师的数据,虽然进口商品的具体关税水平各不相同,从钢铁和铝的 50% 到消费品的 7.5% 不等,但目前从中国进口商品的所谓实际关税税率为 40%。 加征为"报复"性举措, 特朗普声称"拭目以待" 这一宣布,是在特朗普威胁要 "大幅提高" 从中国进口商品的关税以回击中国对稀土矿物实施新的出 口管制措施数小时后作出的。 整理 | 华卫 刚刚,美国总统唐纳德・特朗普(Donald Trump)宣布,美国将从 11 月 1 日起对从中国进口的商 品征收 100% 的新关税,"这一关税高于目前已征收的任何关税"。特朗普还称,美国将在同一天对 "所有关键软件" 实施出口管制。 全球约 70% 的稀土矿物供应来自中国。稀土矿物对于制造微芯片和半导体至关重要,这些芯片和半 导体被用于人工智能技术和电子产品。中国商务部于 10 月 9 日表示,自 12 月 1 日起,外国实体若 要出口以下两类产品,必须获得许可证:一是产品中源自中国的稀土含量超过 0.1%;二是采用中国 的稀土开采、冶炼分离、磁体制造或回收技术生产的产品。 这些新 ...

如果您希望可以时常见面,欢迎标星收藏哦~ 来 源 :内容来自 semiconductor-digest 。 约翰霍普金斯大学的研究人员发现了一种新材料和一种新工艺,这可能会推动在制造更小、更快、 更经济的微芯片方面的持续竞争。这些微芯片被用于现代电子产品中的方方面面——从手机到汽 车,从家电到飞机。 该科学家团队发现了一种既精确又经济的制造工艺,可以创造出肉眼不可见的微小电路。 这项发现今天发表在《自然化学工程》(Nature Chemical Engineering)杂志上。 然而,需要更高功率的辐射光束才能在芯片上刻出更小的细节,但这些光束与传统光刻胶的相互作 用不够强烈。 此 前 , 察 帕 特 西 斯 实 验 室 和 约 翰 霍 普 金 斯 大 学 费 尔 布 拉 瑟 研 究 小 组 ( Fairbrother Research Group)的研究人员发现,由一类新型金属有机物制成的光刻胶可以适应这种更高功率的辐射工 艺,即"超越极紫外辐射"(B-EUV)。该技术有潜力制造出比目前标准尺寸10纳米更小的细节。 锌等金属能吸收B-EUV光,并产生电子,从而引发必要的化学转化,将电路图案印刻在一种名为 咪 ...
