Khoom Description
Poly-crystalline silicon, tseem hu ua poly-silicon lossis poly-Si, yog lub siab purity, poly-crystalline daim ntawv ntawm silicon, siv los ua raw khoom los ntawm hnub ci photovoltaic thiab electronics kev lag luam. Poly-silicon yog tsim los ntawm metallurgical qib silicon los ntawm cov txheej txheem tshuaj purification, hu ua Siemens txheej txheem. Cov txheej txheem no suav nrog distillation ntawm cov tshuaj silicon tsis muaj zog, thiab lawv decomposition rau hauv silicon ntawm qhov kub thiab txias. Ib qho kev tawm tshiab, lwm txoj hauv kev ntawm kev ua kom zoo dua siv lub txaj fluidized reactor.
Kev lag luam photovoltaic kuj tseem tsim kho qib metallurgical-qib silicon (UMG-Si), siv metallurgical es tsis txhob siv tshuaj purification txheej txheem. Thaum tsim tawm rau kev lag luam hluav taws xob, poly-silicon muaj cov impurity tsawg dua ib feem ntawm ib billion (ppb), thaum poly-crystalline hnub ci qib silicon (SoG-Si) feem ntau tsis tshua muaj ntshiab.
Poly-silicon pub-Tshuag - cov pas nrig loj, feem ntau tawg mus rau hauv chunks ntawm qhov ntau thiab tsawg thiab ntim rau hauv cov chav huv si ua ntej xa khoom - yog ncaj qha nrum rau hauv cov khoom siv crystalline ntau lossis xa mus rau cov txheej txheem recrystallization kom loj hlob ib leeg siv lead ua boules. Cov khoom yog ces hlais rau hauv nyias silicon wafers thiab siv rau zus tau tej cov hnub ci hlwb, integrated circuits thiab lwm yam semiconductor li.
Silicon sputtering lub hom phiaj, raws li cov ntaub ntawv tseem ceeb heev, nws tsuas yog siv rau kev tso nyiaj SiO2, Si3N4 thiab lwm cov txheej txheem dielectric los ntawm cov txheej txheem sib nqus. Cov yeeb yaj kiab nyias nyias muaj cov yam ntxwv zoo heev, qhov muag pom, dielectric zog, hnav thiab corrosion kuj, uas yog dav siv rau thaj tsam ntawm LCD pob tshab iav iav, LOW-E lub tsev iav thiab micro-electronics.
