High Purity Quartz Nkoj rau Silicon Wafer

Hauv ntiaj teb ntawm kev tsim khoom semiconductor, qhov tseeb thiab kev huv yog qhov tseem ceeb. Lub nkoj quartz yog ib qho khoom siv tseem ceeb uas siv los tuav thiab hloov cov silicon wafers thaum lub sijhawm ua haujlwm kub ntau yam.

Cov nkoj quartz yog qhov tseem ceeb hauv ntau theem tseem ceeb ntawm kev tsim wafer:

● Kev sib kis: Hauv cov txheej txheem no, lub nkoj quartz tuav cov silicon wafers thaum lawv raug cua sov hauv lub cub tawg kom qhia cov dopants zoo li boron, phosphorus, lossis arsenic. Qhov huv si ntawm quartz ua kom ntseeg tau tias cov dopants no tsis muaj kuab paug, uas yog qhov tseem ceeb rau kev ua tiav

cov khoom hluav taws xob xav tau.

● Kev Oxidation: Thaum lub sijhawm oxidation, cov wafers raug cua sov hauv lub cub tawg kub nrog oxygen kom loj hlob ib txheej nyias nyias ntawm silicon dioxide (SiO2) rau ntawm lawv qhov chaw. Cov txheej no ua haujlwm ua ib qho insulator, ib qho kev tiv thaiv, thiab ib qho khoom siv masking.

● Kev Tso Pa Tshuaj Lom (CVD): Cov txheej txheem no tso cov zaj duab xis nyias nyias ntawm cov ntaub ntawv rau ntawm cov wafers los ntawm lub xeev vapor. Cov nkoj quartz yog siv los tuav cov wafers hauv CVD reactor, qhov chaw uas lawv raug rau cov pa roj reactive ntawm qhov kub siab.

● Kev Kub Hnyiab: Kev kho cua sov no yog siv los kho qhov tsis zoo, ua kom cov dopants ua haujlwm, thiab txo kev ntxhov siab hauv cov qauv siv lead ua ntawm cov silicon wafers tom qab ion implantation lossis lwm cov txheej txheem muaj zog siab.

Qhov zoo ntawm lub nkoj quartz ncaj qha cuam tshuam rau qhov tsim tawm thiab kev ua tau zoo ntawm silicon wafers. Peb cov nkoj quartz siab-purity muab cov txiaj ntsig zoo rau koj cov txheej txheem:

● Kev Huv Si Zoo Kawg Nkaus: Peb cov khoom siv quartz muaj cov ntsiab lus tsawg heev ntawm cov hlau tsis huv (<10ppm), xws li K, Na, thiab Li. Qhov no yog qhov tseem ceeb hauv kev tsim khoom semiconductor, qhov twg txawm tias cov khoom tsis huv me me tuaj yeem ua haujlwm ua dopants, ua rau muaj qhov tsis zoo thiab txo qhov kev ua haujlwm hluav taws xob ntawm cov chips tiav lawm.

● Kev Ruaj Ntseg Thermal Zoo Tshaj Plaws: Qhov kev tiv taus cua sov siab ntawm peb cov nkoj quartz tso cai rau lawv kom nyiaj tau sai sai cua sov thiab txias yam tsis tawg lossis deforming. Qhov no ua rau lub neej ntawm cov khoom siv ntev dua thiab txo qis lub sijhawm tsis ua haujlwm. Peb cov nkoj quartz tuaj yeem tiv taus kev siv tas mus li ntawm qhov kub txog li 1200C.

● Kev Tiv Thaiv Kub Siab: Nrog rau qhov kub ua haujlwm txog li 1200C, peb cov nkoj quartz zoo meej rau cov chaw kub heev uas xav tau rau kev sib kis, oxidation, thiab annealing.

● Kev Tiv Thaiv Kev Xeb Zoo heev: Cov khoom siv quartz yog cov tshuaj tiv taus tshuaj lom neeg los ntawm cov kua qaub thiab lwm yam tshuaj corrosive siv rau hauv cov txheej txheem wafer, kom ntseeg tau tias muaj kev ruaj khov thiab kev ntseeg siab ntev.

Kev lag luam semiconductor xav tau qhov tseeb, kev sib xws, thiab kev dawb huv. Nrog Semixlab's High Purity Quartz Boats, koj tau txais kev ntseeg siab ntawm kev ua wafer ruaj khov, txo qis kev ua qias tuaj, thiab ua kom zoo tshaj plaws. Tiv tauj peb hnub no los tham txog cov kev daws teeb meem rau koj cov kev xav tau ua silicon wafer.
