Khoom Description
Hlau silicon polysilicon yog cov ntaub ntawv tseem ceeb siv hauv kev tsim cov khoom siv hluav taws xob thiab lwm yam khoom siv hluav taws xob. Cov ntaub ntawv no tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho thev naus laus zis thiab txhim kho tib neeg lub neej. Muaj ntau qib ntawm cov hlau silicon polysilicon muaj, txhua tus muaj cov yam ntxwv tshwj xeeb thiab cov yam ntxwv uas ua rau lawv tsim nyog rau cov ntawv thov tshwj xeeb.
Ib qho tseem ceeb ntawm kev siv hlau silicon polysilicon yog nyob rau hauv kev tsim cov hnub ci hlwb. Polysilicon yog cov khoom siv tseem ceeb hauv kev tsim cov hnub ci hlwb, thiab hlau silicon feem ntau yog siv los ua dopant los txhim kho kev ua haujlwm ntawm cov hlwb. Kev siv cov ntaub ntawv no tau ua rau nws muaj peev xwm tsim cov tshuab hluav taws xob zoo hnub ci uas muaj txiaj ntsig zoo thiab txhim khu kev qha.
Lwm daim ntawv thov tseem ceeb ntawm cov hlau silicon polysilicon yog nyob rau hauv kev tsim cov khoom siv computer. Cov ntaub ntawv no muab cov khoom tsim nyog uas yuav tsum tau ua los tsim cov kev sib txuas sib txuas hauv cov khoos phis tawj niaj hnub thiab lwm yam khoom siv hluav taws xob. Lawv siv hauv cov ntawv thov no tau ua rau muaj kev txhim kho tseem ceeb hauv kev suav lub zog thiab kev cia khoom.
Muaj ntau qib ntawm cov hlau silicon polysilicon muaj rau siv nyob rau hauv ntau daim ntawv thov. Piv txwv li, muaj ntau qib sib txawv ntawm polysilicon nyob ntawm seb qhov purity yuav tsum tau ua. Cov qib purity siab dua yog xav tau rau kev tsim hluav taws xob hnub ci, thaum qis purity qib tuaj yeem siv rau hauv lwm yam kev siv.
Ib yam li ntawd, muaj cov qib sib txawv ntawm cov hlau silicon uas sib txawv hauv lawv cov dopant concentration. Qhov no tso cai rau kev tswj xyuas meej ntawm cov khoom ntawm cov khoom tsim tawm, ua rau lawv tsim nyog siv rau hauv cov ntawv thov tshwj xeeb.
Tsis tas li ntawd, kev nce qib hauv thev naus laus zis tau ua rau kev txhim kho cov qib tshiab ntawm cov hlau silicon polysilicon nrog cov khoom zoo dua qub. Piv txwv li, muaj cov qib tshiab ntawm polysilicon uas xav tau lub zog tsawg dua los tsim thiab muaj cov pa roj carbon tsawg dua cov qib qub.
Kev siv ntau ntawm cov hlau silicon polysilicon tau ua rau muaj txiaj ntsig zoo rau tib neeg. Cov ntaub ntawv no tau ua rau kev tsim cov khoom siv hluav taws xob muaj txiaj ntsig zoo thiab txhim khu kev qha thiab tau pab txhawb kev loj hlob ntawm lub zog tauj dua tshiab. Lawv kuj tau pab tsim cov hauj lwm thiab txhawb kev loj hlob ntawm kev lag luam hauv ntau lub teb chaws.
Tsis tas li ntawd, kev nce qib hauv kev siv thev naus laus zis ntsig txog hlau silicon polysilicon ntau lawm tau coj mus rau kev tsim cov txheej txheem tsim tshiab uas muaj kev nyab xeeb dua qub. Kev siv lub zog tauj dua tshiab xws li cua thiab hnub ci zog hauv kev tsim cov khoom siv no tau txo lawv cov kev cuam tshuam ib puag ncig thiab ua rau lawv muaj kev xaiv zoo dua.
Hauv kev xaus, hlau silicon polysilicon yog cov ntaub ntawv tseem ceeb siv hauv kev tsim cov khoom siv hluav taws xob, lub hnub ci hlwb, thiab lwm yam khoom siv hluav taws xob. Qhov muaj ntau qib ntawm cov ntaub ntawv no nrog cov khoom sib txawv tau tso cai rau kev tswj xyuas meej ntawm cov khoom siv thiab lawv qhov tsim nyog rau cov ntawv thov tshwj xeeb. Kev siv cov hlau silicon polysilicon tau ua rau muaj txiaj ntsig zoo rau tib neeg, suav nrog kev nce qib ntawm kev siv thev naus laus zis, kev loj hlob ntawm lub zog txuas ntxiv mus, thiab kev tsim cov haujlwm thiab kev loj hlob ntawm kev lag luam. Tsis tas li ntawd, kev nce qib hauv kev siv thev naus laus zis cuam tshuam nrog kev tsim cov khoom siv no tau ua rau ntau qhov kev tsim khoom zoo ib puag ncig, ua rau lawv muaj kev xaiv zoo dua rau yav tom ntej.
