Raws li peb txhua tus paub, cov khoom siv uas txwv tsis pub muaj kev nce qib ntawm kev tsim khoom tsim hluav taws xob hauv lub teb chaws yog lub tshuab lithography, vim tias lub tshuab lithography siab tshaj plaws nyob hauv lub ntiaj teb yog ASML' s EUV lithography tshuab, uas yog siv rau kev tsim cov chips ntawm 7nm thiab hauv qabthiab xwbtsim los ntawmASML. Tab sis nws tsis tuaj yeem muag rau Tuam Tshoj Teb Chaws.
Lub zog muaj zog nyeg lithium tshuab tsim los ntawm Shanghai Microelectronics tseem nyob ntawm 90nm. Raws li kev lag luam sab hauv, qhov kis ntawm peb thiab ASML yuav tsum muaj ntau dua 10 xyoo.
Vim tias peb tsis tuaj yeem yuav EUV lithography tshuab, tam sim no peb lub tshuab tsim chip tam sim no tseem nyob ntawm 14nm, yog li kev txhim kho ntawm peb tus kheej lub tshuab lithography tau dhau los ua qhov tseem ceeb tshaj plaws ntawm kev ua lag luam chip tam sim no.
Tsis ntev los no, ib tsab xov xwm tau tawm tias Huawei kuj tseem pib xa cov tshuab lithography. Hubble Investment, uas tshwj xeeb hauv kev nqis peev hauv kev lag luam semiconductor raws li Huawei, tau tso peev kev lag luam hauv Beijing Keyi Hongyuan Optoelectronics Technology Co., Ltd.
Kev koom ua ke yog kwv yees li 4.7619%, thiab cov peev txheej yog kwv yees li 10 lab yuan. Tam sim no, cov peev sau npe ntawm Keyi Hongyuan tau dhau los ua 20.16 lab yuan.
Lub hauv paus pib ntawm Keyi Hongyuan yog dab tsi? Nws yog tib lub tuam txhab nyob hauv Suav teb thiab lub tuam txhab thib peb hauv ntiaj teb nrog 193nm ArF excimer laser tshuab tshawb fawb thiab kev ua lag luam.
Xyoo 2018, thawj kev tsim tawm hauv tsev high-energy excimer laser ywj siab thiab tsim los ntawm Keyi Hongyuan tau ua tiav kev xa khoom. Nws tam sim no lub teeb ci zog cov chaw muag khoom ntawm domestic lithography tshuab chaw tsim tshuaj paus Shanghai Microelectronics.
Ib qho ntxiv, Keyi Hongyuan kuj tau ua tiav cov phiaj xwm tshwj xeeb hauv teb chaws xws li" 02 Lub Tuam Txhab Tshwj Xeeb Tshwj Xeeb Kev Siv Hluav Taws Xob Chaw Teeb Tshawb Nrhiav thiab Kev Tsim Kho" ;," 02 Qhov Tseem Ceeb Tshwj Xeeb Project Tub Ntxhais Kev Tsim Kev Muaj Peev Xwm Tsim Kev Muaj Peev Xwm Tsev" ;," Tshwj Xeeb Txuas Circuit Court Wafer Txheeb Xyuas Qhov Teeb Pom Zoo" thiab lwm qhov haujlwm tshwj xeeb hauv tebchaws. Nws tau hais tias tam sim no nws yog qhov muaj zog tshaj plaws hauv kev lag luam hauv cov tub ntxhais thev naus laus zis ntawm tshuab lithography.
Tau kawg, muaj ntau cov ntsiab lus tseem ceeb hauv lub tshuab lithography. Piv txwv li, ASML' s EUV lithography tshuab muaj ntau tshaj 100,000 qhov chaw. Lub teeb ci tsuas yog ib feem ntawm nws. Tab sis yog tias koj xav kom kov yeej lub tshuab lithography, qhov chaw teeb pom kev no yog qhov tseem ceeb. Qhov ntu uas yuav tsum kov yeej yog qhov tseem ceeb ntawm tub ntxhais.
Yog li no, Huawei Hubble' s peev hauv Keyi Hongyuan yog qhov pom tseeb los txhim kho cov txheej txheem ntawm kev tshawb fawb thiab kev txhim kho hauv kev ua haujlwm ntawm cov tshuab lithography. Tom qab tag nrho, Huawei tam sim no xav tau domestic chip tsim thev naus laus zis kom nce.
