- Cov ntsiab lus hlau:Hlau, raws li lub ntsiab impurity, yuav tsum tau nruj me ntsis tswj. Cov ntsiab lus ntawm cov hlau hauv hlau silicon 1101 feem ntau yuav tsum tsis pub ntau tshaj 0.1%.
- Aluminium cov ntsiab lus:Cov ntsiab lus txhuas muaj kev cuam tshuam zoo rau cov khoom siv hluav taws xob thiab kev tiv thaiv corrosion ntawm silicon, thiab cov ntsiab lus txhuas ntawm cov hlau silicon 1101 yuav tsum tsawg dua 0.01%.
- Cov ntsiab lus calcium:Raws li lub ntsiab lus impurity, muaj cov calcium uas yuav cuam tshuam rau lub zog thiab ua haujlwm ntawm silicon, thiab cov ntsiab lus yuav tsum tsis pub ntau tshaj 0.01%.
- Cov ntsiab lus phosphorus:Phosphorus yog ib qho teeb meem impurities hauv silicon, uas yuav cuam tshuam rau cov hluav taws xob conductivity ntawm silicon, thiab feem ntau yuav tsum muaj cov ntsiab lus phosphorus tsawg dua 0.001%.
- Cov ntsiab lus sulfur:Cov ntsiab lus sulfur yuav tsum tau tswj nruj me ntsis, vim hais tias nws yuav ua rau kom lub brittleness ntawm silicon, thiab cov ntsiab lus sulfur nyob rau hauv hlau silicon 1101 yuav tsum tsis pub tshaj 0.001%.
- Cov ntsiab lus carbon:Cov pa roj carbon impurities tuaj yeem cuam tshuam cov khoom siv hluav taws xob ntawm silicon, yog li yuav tsum muaj cov ntsiab lus carbon tsawg dua 0.005%.
- Cov ntsiab lus chlorine:Cov ntsiab lus chlorine yuav tsum nruj me ntsis tswj nyob rau hauv kev tsim cov high-purity silicon, feem ntau yuav tsum tau tsawg tshaj li 0.001%.
3. Kev kuaj xyuas lub cev(Dab tsi yog qhov kev soj ntsuam zoo ntawm silicon hlau 1101?)
- Particle loj faib:Silicon hlau 1101 feem ntau yog ua tiav rau hauv cov khoom los yog hmoov, thiab nws cov khoom loj me me yuav tsum tau ua kom tau raws li cov neeg siv khoom xav tau. Qhov loj particle loj nyob ntawm 1-10mm, thiab cov ntawv thov tshwj xeeb yuav xav tau kev faib tawm ntau dua.
- Ceev thiab purity uniformity:Qhov ceev yuav tsum nyob rau hauv tus qauv ntau yam kom ntseeg tau tias tsis muaj qhov tsis zoo hauv cov khoom siv thiab nws muaj lub cev tsis sib xws.
- Inductively coupled Plasma Emission Spectroscopy (ICP-OES):Siv los txheeb xyuas cov kab hauv silicon, nrog rau cov impurities xws li hlau, txhuas, thiab calcium.
- Inductively coupled Plasma Mass Spectrometry (ICP-MS):Kev txiav txim siab meej ntawm qib qis ntawm impurity xws li phosphorus thiab sulfur.
- Tshuaj ntsuam xyuas:Kev tshuaj xyuas cov tshuaj ntub dej ib txwm siv los txheeb xyuas qhov purity ntawm silicon, uas tuaj yeem txiav txim siab cov ntsiab lus ntawm cov ntsiab lus tseem ceeb thiab impurities.
- X-ray fluorescence Spectroscopy (XRF):Rau kev tshawb nrhiav sai ntawm cov ntsiab lus tseem ceeb thiab cov impurities hauv silicon, tshwj xeeb tshaj yog rau kev tswj kom zoo hauv cov txheej txheem ntau lawm.
- Particle loj tsom xam:Lub particle loj tis yog txiav txim los ntawm ib tug laser particle loj analyzer los xyuas kom meej tias nws ua tau raws li cov neeg siv yuav tsum tau.
