【台积电的护城河在哪里?制程里用到的EUV技术,极紫外光是什么?】 1. 极紫外光概念 大家可以理解为一种波长较短的紫外光,lithography最早是石版印刷的意思,现在也被用来称呼为光刻技术,所以把他们两者合起来就是“利用极紫外光来进行雕刻”的意思,那要雕什么呢?要雕晶圆。 2. 股价攀升原因? 虽然三星、Intel英特尔也有EUV光刻机/曝光机,但是最终能够驾驭这个技术并成功量产的还是台积电。EUV的成果是台积电股价可以攀升的原因之一。为什么呢?因为台积电在这个制程领先才能在7奈米、5奈米上领先对手三星、Intel,让订单持续涌入。 3. 防尘技术突破 台积电在防尘技术上的突破,就算是一颗奈米级的灰尘也会因此影响半导体厂的生产良率,而EUV光刻机对于防尘的要求又比过去采用DUV光刻机时更高,因此在三星及Intel都还卡在防尘处理这关时,台积电成功改良了光罩防尘技术,就因此让TSMC成为全球首间导入EUV技术并且达成量产的厂商,在7奈米的订单上大幅超越死敌三星。 #中国首届财经视频大赛# #投资# #科普#
