Kev hloov pauv ntawm cov nqi silicon wafer cuam tshuam cov nqi tsim khoom
Txij li thaum silicon wafers tau siv dav hauv kev lag luam xws li kev tsim khoom siv hluav taws xob thiab kev lag luam hnub ci, qhov nce thiab nqis ntawm lub voj voog kev lag luam yuav muaj kev cuam tshuam rau tus nqi, thiab kev hloov pauv ntawm cov khoom siv silicon tus nqi yuav cuam tshuam ncaj qha rau cov nqi tsim khoom ntawm silicon wafers. Raws li PVInfoLink cov ntaub ntawv, nyob rau hauv lub ntiaj teb no silicon wafer tus nqi sib txawv, tus nqi ntawm monocrystalline silicon wafers 210 hli, monocrystalline silicon wafers 182 hli, thiab monocrystalline silicon wafers 166 hli yog cuam tshuam los ntawm kev lag luam xav tau thiab fluctuate nyob rau hauv ib tug tej yam ntau yam. Pib txij lub Rau Hli 2021, cov nqi silicon wafer tau nkag mus rau qhov nce siab thiab mus txog qhov siab tshaj plaws nyob rau lub Yim Hli 2022, nrog kev loj hlob muaj zog. Nrog rau kev nce qib ntawm cov thev naus laus zis tas li, cov txheej txheem tsim khoom ntawm silicon wafers tau ua kom zoo dua thiab cov nqi tau txuas ntxiv mus. Tsis tas li ntawd, txij li ib nrab xyoo 2022, qhov kev cuam tshuam los ntawm kev tsis sib haum xeeb ntawm cov khoom siv thiab kev xav tau hauv kev lag luam semiconductor thoob ntiaj teb tau ua rau ntiaj teb cov nqi silicon wafer hloov pauv thiab poob rau xyoo dhau los.
Ntiaj teb no silicon wafer kev lag luam lag luam loj
Silicon wafer xa khoom nyob ruaj khov, kev lag luam loj hlob sai
Silicon-based semiconductor cov ntaub ntawv tam sim no yog cov khoom siv semiconductor nrog cov zis ntau tshaj plaws thiab siv dav tshaj plaws. Daim ntawv thov teb ntawm semiconductors txuas ntxiv nthuav dav nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis. Kev lag luam tawm tshiab xws li Is Taws Nem ntawm Yam, kev txawj ntse, thiab kev suav huab tau nthuav dav, coj txoj hauv kev loj hlob tshiab rau kev lag luam semiconductor silicon wafer. Txij li xyoo 2018, lub ntiaj teb semiconductor silicon wafer xa khoom tau qhia txog kev nce siab thaum muaj kev hloov pauv.

Tau txais txiaj ntsig los ntawm cov ntawv thov tshiab thiab cov npe nrov ntawm 12-inch silicon wafers, kev xa khoom thoob ntiaj teb silicon wafer yuav tsum tshaj 15 billion square inches yav tom ntej. . Raws li SEMI cov ntaub ntawv, lub ntiaj teb no semiconductor silicon wafer kev lag luam loj tseem nyob ntawm US $ 11 billion los ntawm 2018 txog 2020. Pib xyoo 2021, nrog rau kev sib txawv ntawm kev tsim cov khoom siv davhlau ya nyob twg, kev lag luam kuj tau nkag mus rau lub sijhawm ntawm kev loj hlob sai. Nws cia siab tias thaum kawg ntawm 2023, lub ntiaj teb semiconductor silicon wafer kev lag luam loj yuav tsum tshaj US $ 14 billion.
Tuam Tshoj silicon wafer kev lag luam lag luam loj
Silicon wafer ntau lawm txuas ntxiv mus, thiab kev lag luam hauv qab yog loj heev
Txij li thaum xyoo 2018, kuv lub teb chaws cov khoom siv silicon wafer feem ntau qhia txog kev loj hlob txhua xyoo. Raws li CPIA cov ntaub ntawv, kuv lub teb chaws cov khoom siv silicon wafer tau nkag mus rau lub sijhawm siab tshaj plaws txij li xyoo 2021, nrog rau kev loj hlob sai. Nrog rau kev nthuav dav ntawm cov tuam txhab ua lag luam, kev siv thev naus laus zis tsis tu ncua thiab kev loj hlob ntawm cov kev xav tau qis qis, cov khoom siv silicon wafer yuav tsum tshaj 400GW yav tom ntej. Nyob rau hauv xyoo tas los no, kuv lub teb chaws txoj kev lag luam silicon wafer tau tsim sai heev, thiab kev loj hlob ntawm cov lag luam hauv tsev loj tau tshaj qhov nruab nrab ntawm kev loj hlob thoob ntiaj teb. Raws li SEMI cov ntaub ntawv, kuv lub teb chaws lub semiconductor silicon wafer kev lag luam loj tshaj 10 billion yuan hauv kev lag luam loj los ntawm 2021 txog 2022, thiab qhov kev loj hlob tau txuas ntxiv mus. Nws xav tias yuav dhau 15 billion yuan hauv kev lag luam loj nyob rau yav tom ntej, thiab muaj chaw dav rau kev lag luam loj hlob.
