港媒:中國芯片領域研究又有新突破!
港媒稱,內地的科學家說,他們已經研發出一種晶體管,這種晶體管將大大增強芯片
的性能,並大幅降低它們的能耗。
據香港《南華早報》網站5月27日報導,現如今,市場上最先進的計算機芯片使用7納
米晶體管。中國科學院微電子研究所微電子設備與集成技術領域的專家殷華湘說,他的團
隊已經研發出3納米晶體管——相當於一條人類DNA鏈的寬度,在一個指甲蓋大小的芯片上
能安裝數百億個這種晶體管。
殷華湘說,晶體管變得越小,芯片上就能安裝越多的晶體管,這會讓處理器的性能顯
著提升。晶體管是處理器的基本部件。殷華湘說,用3納米晶體管製造的處理器將會增加
計算速度,並降低能耗。比如一位智能手機用戶可以整天玩需要大量計算能力的遊戲,卻
不需要為電池重新充電。
殷華湘說,他的團隊還必須克服一些重大障礙。他們的研究成果本月部分發表在同行
評議雜誌《電氣與電子工程師協會電子器件通訊》上。其中一個障礙是“波爾茲曼暴政”
。路德維希·波爾茲曼是19世紀的奧地利物理學家。“波爾茲曼暴政”描述的是有關電子
在一個空間中的分佈問題。對芯片研發者來說,這意味著隨著更多較小的晶體管安裝到芯
片上,晶體管所需電流產生的熱量將燒燬芯片。
報導稱,物理學家已經為這個問題提供瞭解決辦法。殷華湘說,他的團隊使用一種稱
為“負電容”的方法,這樣他們能用理論上所需最小電量的一半電量來為晶體管提供電力
。這種晶體管實現商業應用可能要花幾年時間。該團隊正在進行材料和質量控制方面的工
作。
殷華湘說:“這是我們工作中最激動人心的部分。這不僅是實驗室中的又一項新發現
。它有著實際應用的巨大潛力。而我們擁有專利。”
報導稱,殷華湘說,這項突破將讓中國“在芯片研發的前沿同世界頭號角色進行正面
競爭”。他說:“在過去,我們看著其他人競爭。現在,我們在同其他人競爭。”
據報導,中國還在研發一種原子大小(0.5納米)的晶體管,而其他國家已經加入將3
納米晶體管投入市場的競賽。
韓國三星公司說,它計畫到明年上半年完成3納米晶體管的研發。三星說,同7納米技
術相比,用它的3納米晶體管製造的處理器只需用一半的電力,性能卻會提高35%。三星沒
有說它預計這些芯片將於何時投產。
3.心得/評論:
中國又彎道超車了
這次是3nm技術
在華為被封鎖的情況下
中國科技迎來新的突破~!!!
