AchifukidziroChidimbu chesilicon chine ukobvu hwe 1 millimeter uye chine nzvimbo yakati sandara zvakanyanya nekuda kwemaitiro anoda simba rakawanda. Kushandiswa kunotevera kunosarudza kuti ndeipi nzira yekurima kristalo inofanira kushandiswa. Semuenzaniso, muCzochralski process, polycrystalline silicon inonyungudutswa uye kristalo yembeu yakatetepa inonyikwa musilicon yakanyungudutswa. Kristaro yembeu inozotenderedzwa uye inodhonzwa zvishoma nezvishoma kumusoro. Colossus inorema kwazvo, monocrystal, inobuda. Zvinokwanisika kusarudza hunhu hwemagetsi hwemonocrystal nekuwedzera mayuniti madiki edopants dzakachena zvakanyanya. Makristaro anoiswa dope zvichienderana nezvinodiwa nemutengi uye obva akweshwa uye ochekwa kuita zvidimbu. Mushure mematanho akasiyana-siyana ekugadzira, mutengi anogamuchira wafers dzake dzakatarwa mupakeji yakakosha, iyo inobvumira mutengi kushandisachifukidziropakarepo mumutsara wayo wekugadzira.
Nhasi, chikamu chikuru chesilicon monocrystals chinorimwa zvichienderana nemaitiro eCzochralski, ayo anosanganisira kunyungudutsa polycrystalline high-purity silicon mu hyperpure quartz crucible uye kuwedzera dopant (kazhinji B, P, As, Sb). Kristaro yembeu ye monocrystalline yakatetepa inonyikwa musilicon yakanyungudutswa. Kristaro hombe yeCZ inobva yabuda kubva mukristaro iyi yakatetepa. Kudzora kwakanyatsonaka kwekushisa nekuyerera kwesilicon yakanyungudutswa, kutenderera kwekristaro necrucible, pamwe nekumhanya kwekudhonza kristaro zvinoguma ne monocrystalline silicon ingot yepamusoro-soro.
