PSA cov pa oxygen cog rau semiconductor raug

Cov pa Pa:Kev tsim khoom lag luam semanic feem ntau yuav tsum muaj cov pa roj carinal, feem ntau yuav tsum tau mus txog 99.999% lossis siab dua, kom ntseeg tau tias yog qhov zoo thiab ua haujlwm ntawm cov khoom lag luam semiconductor.
Cov pa oxygen Flune:Raws li cov nplai ntau lawm thiab cov txheej txheem uas yuav tsum tau ua ntawm cov khoom lag luam tawm, PSA oxen cov khoom siv kom tau raws li cov txheej txheem oxygen ruaj khov rau hauv cov txheej txheem ntau lawm.
Dew taw tes kub:Cov dej noo noo hauv oxygen yog qhov yuav tsum tau tsawg, thiab cov dew qhov taw tes kub feem ntau yog yuav tsum tau ua kom tsis txhob muaj kev ya raws kev ua haujlwm ntawm cov txheej txheem kev tsim khoom.
Particle Impurity Cov ntsiab lus:Cov ntsiab lus ntawm particulate impurities hauv oxygen yuav tsum nruj me ntsis tswj, feem ntau yuav tsum tau ua kom tsis txhob muaj kev cuam tshuam rau ntawm qhov chaw ntawm cov ceg ntoo semiconductor.

Oxidation yog qhov yooj yim thiab theem tseem ceeb hauv ntau cov txheej txheem txuas ntawm semiconductor raug. Piv txwv li, hauv cov txheej txheem oxidation ntawm silicon wafers, high-purity oxygen yuav tsum tau ua kom cua silicon dioxide (sitio₂) txheej. Qhov no silicon dioxide txheej tuaj yeem siv los ua txheej txheej insulating lossis ua daim npog ntsej muag rau cov txheej txheem tom ntej. Cov khoom siv siab tshaj plaws muab los ntawm psa oxygen cov khoom siv (yog li ntawd cov khoom lag luam zoo li qub, yog li cov khoom lag luam zoo nkauj muaj cov khoom zoo nkauj zoo thiab tuab tuab, uas yog qhov tseem ceeb heev rau kev tsim cov kev ua haujlwm siab semiconductor cov cuab yeej (xws li cov transistors hauv kev sib xyaw ua ke).
