Zeziphi izinto ekrwada zokuvelisa i-polysilicon?

Izixhobo zokuvelisa i-polysilicon ikakhulu ziquka i-silicon ore, i-hydrochloric acid, i-silicon ye-metallurgical grade industrial, i-hydrogen, i-hydrogen chloride, i-silicon powder ye-industrial, i-carbon kunye ne-quartz ore....

...I-silicon ore...: ubukhulu becala i-silicon dioxide (SiO2), enokuthi ikhutshwe kwi-silicon ores efana ne-quartz, isanti ye-quartz, kunye ne-wollastonite....Hydrochloric acid...(okanye i-chlorine kunye ne-hydrogen): isetyenziselwa ukusabela nge-silicon ye-metallurgical grade industrial ukuvelisa i-trichlorosilane....I-silicon yemveliso ye-Metallurgical...: njengenye yezinto eziluhlaza, isabela nge-hydrochloric acid kwiqondo lokushisa eliphezulu ukuvelisa i-trichlorosilane....Ihydrogen...: isetyenziselwa ukunciphisa i-trichlorosilane ukuvelisa iintonga ze-polysilicon ezicocekileyo....I-Hydrogen chloride...: iphendula kunye nomgubo wesilicon yeshishini kwisithando sokudibanisa ukuvelisa i-trichlorosilane....Imveliso ye-silicon powder...: i-quartz ore kunye nekhabhoni iyancitshiswa ukuvelisa iibhloko ze-silicon zoshishino phantsi kwamandla, ezityunyuzwa zibe yi-powder silicon powder....Ezi zixhobo zingena kuluhlu lweekhemikhali kunye neenkqubo zokucoca ukuze ekugqibeleni zifumane izinto ezicocekileyo zepolysilicon. I-Polysilicon yimathiriyeli ekrwada esisiseko yokwenza ii-crystal silicon wafers kwaye isetyenziswa kakhulu kumzi mveliso we-semiconductor, iiseli zelanga kunye nezinye iindawo.

i-polysilicon yimathiriyeli ekrwada ngokuthe ngqo yokuvelisa i-silicon enye yekristale. Yeyona nto isisiseko yolwazi lwe-elektroniki yezixhobo ze-semiconductor ezifana nobukrelekrele bokwenziwa kwangoku, ulawulo oluzenzekelayo, ukusetyenzwa kolwazi, kunye noguqulelo lombane. Ibizwa ngokuba "lilitye lembombo lesakhiwo se-microelectronics."

Abavelisi abakhulu be-polysilicon yi-Hemlock Semiconductor, i-Wacker Chemie, i-REC, i-TOKUYAMA, i-MEMC, i-Mitsubishi, i-Sumitomo-Titanium, kunye nabavelisi abancinci e-China. Iinkampani ezisixhenxe eziphezulu zivelise ngaphezulu kwe-75% yemveliso ye-polysilicon yehlabathi ngo-2006.
