※ 引述《NaMgAl (那美女)》之銘言:
: 台積電5奈米完勝三星 高通指「供應吃緊」有內情
: https://ec.ltn.com.tw/article/breakingnews/3431887
: 2021/02/04
: 高通獲利不如市場預估,高通指出是因為產能吃緊緣故,
: 若是代工廠能生產更多晶片,高通可以賣更多,
: 但市場認為最主要的原因仍是三星良率的問題,
: 因此估計高通下一代 S895手機晶片會委由台積電五奈米生產。
今天曲博科技教室的直播節目有提到目前推測到的三星五奈米翻車原因
https://www.youtube.com/watch?v=P5fJ2hAnu4c
推測主要是opc技術不夠完美導致後段製程金屬導線電阻過高
這個部份的完善推測 "至少" 要半年才有 "機會" 趕上
另外還有提到目前接受到的訊息是S895會轉給台積電來做
詳情可以參考上面附的連結
個人認為比較有趣的是
三星5nm是7nm的架構,最小金屬導線間距是36nm
台積電公布的5nm最小金屬導線間距是40nm的70%,可以理解為28nm嗎?
也就是微縮走向下一個節點的時候
opc的技術差異放大造成良率問題
如果是這樣,那很難想像只是半年就可以改善
因為這個改善包含光罩、euv的應用、蝕刻......etc.
幾乎等於要三星邁進3nm的技術節點了
從這個角度來看,似乎可以大膽樂觀預估三星的5nm對決台積電會輸掉一整個世代
直到三星3nm出來才有改善的可能
不知道大家怎麼看這個消息?
目前網路新聞英文的部分也沒有找到有人提到opc這一塊
