Awaferbụ iberibe silicon gbara ọkpụrụkpụ 1 millimita nke nwere elu dị larịị nke ukwuu n'ihi usoro na-achọsi ike nke ọma. Ojiji na-esote na-ekpebi usoro nke itolite kristal kwesịrị itinye n'ọrụ. N'ime usoro Czochralski, dịka ọmụmaatụ, a na-agbaze silicon polycrystalline na kristal mkpụrụ pensụl dị mkpa na-etinye n'ime silicon a wụrụ awụ. A na-atụgharị mkpụrụ kristal ma jiri nwayọọ nwayọọ na-ebuli elu. Colossus dị arọ nke ukwuu, monocrystal, na-arụpụta. Ọ ga-ekwe omume ịhọrọ njirimara eletriki monocrystal site na ịgbakwunye obere nkeji nke dopants dị ọcha. A na-edobe kristal dị ka nkọwa ndị ahịa si dị, wee na-egbuke egbuke ma bee n'ime mpekere. Mgbe usoro mmepụta ihe dị iche iche gasịrị, onye ahịa na-enweta wafers ya kpọmkwem na nkwakọ ngwaahịa pụrụ iche, nke na-enye ndị ahịa ohere ijiwaferozugbo na ya mmepụta akara.

Taa, a na-etolite akụkụ buru ibu nke silicon monocrystals dị ka usoro Czochralski si dị, nke gụnyere ịgbaze silicon polycrystalline dị ọcha na hyperpure quartz crucible na-agbakwụnye dopant (na-emekarị B, P, As, Sb). A na-etinye mkpụrụ kristal dị gịrịgịrị, nke monocrystalline n'ime silicon a wụrụ awụ. Otu nnukwu kristal CZ wee malite site na kristal dị gịrịgịrị. Usoro ziri ezi nke okpomọkụ na mmiri silik a wụrụ awụ, kristal na ntughari ntughari, yana kristal na-adọkpụ ọsọ na-arụpụta silicon monocrystalline ingot dị oke elu.
