如果您希望可以时常见面，欢迎标星收藏哦~ 人工智能的蓬勃发展对日本小型芯片制造材料供应商 Nitto Boseki 来说是一件好事。 日东纺（Nittobo）公司控制着全球高端玻璃纤维布市场约 90% 的份额，这种近乎垄断的地位帮助 公司提高了利润，并使其股价在今年上涨了 55% 以上。 现在，客户和股东们都强烈要求这家总部位于东京的公司扩大产能，以满足不断增长的需求。 但日东纺CEO多田博之表示，公司将继续坚持当初使其取得今天成就的战略：质量重于数量。 "以与市场相同的速度扩张产能是有风险的，"多田告诉《日经亚洲》。"我们不会成为一家拥有庞 大产能、大量生产大宗商品的公司。" 高端玻璃纤维织物是制造芯片基板的关键材料，而芯片基板正是构建中央处理器和图形处理器等先 进芯片的材料。 日东纺几乎生产了世界上所有最优质的这种组件，即低热膨胀系数玻璃。低热膨胀系数玻璃对于英 伟达、AMD、高通、博通和台积电等顶级芯片制造商至关重要。 多田承认，他的公司一直难以满足激增的需求。他表示，人工智能的出现和数据中心建设的热潮， 引发了一场规模超过以往任何周期的繁荣，包括1995年前后的个人电脑热潮和2010年前后的智能 手机 ...
