SILICON WAFER

SILICON WAFER

kubva ku sitronic

Awaferchimedu chesilicon chinenge mirimita mukobvu icho chine nzvimbo yakati sandarara zvakanyanya nekuda kwemaitiro ari kudiwa zvakanyanya. Iko kushandiswa kunotevera kunotarisisa kuti ndeipi nzira yekukura kwekristaro inofanira kushandiswa. Muchiitiko cheCzochralski, semuenzaniso, iyo polycrystalline silicon inonyungudutswa uye penzura-tete mhodzi kristaro inonyikwa musilicon yakanyungudutswa. Mbeu yekristaro inobva yatenderedzwa uye yokweverwa zvishoma nezvishoma kumusoro. Iyo inorema kwazvo colossus, monocrystal, inoguma. Zvinokwanisika kusarudza maitiro emagetsi e monocrystal nekuwedzera zvidimbu zviduku zvepamusoro-kuchena dopants. Iwo makristasi anodonhedzwa zvinoenderana nezvinodiwa nemutengi uye obva akwenenzverwa uye akachekwa kuita zvimedu. Mushure mematanho akasiyana ekuwedzera ekugadzira, mutengi anogashira zvimedu zvakatemwa mupakeji yakakosha, iyo inobvumira mutengi kushandisawaferpakarepo mumutsara wayo wekugadzira.

Nhasi, chikamu chikuru chesilicon monocrystals inokura maererano neCzochralski process, iyo inosanganisira kunyungudutsa polycrystalline yakakwirira-kuchena silicon mu hyperpure quartz crucible uye kuwedzera dopant (kazhinji B, P, As, Sb). Kristini yembeu yakatetepa, monocrystalline inonyikwa musilicon yakanyungudutswa. Kristini hombe yeCZ inobva yakura kubva pakiristaro iyi nhete. Kunyatso kudzora kweyakanyungudutswa silicon tembiricha uye kuyerera, iyo crystal uye crucible kutenderera, pamwe nekristaro yekudhonza kumhanya inoguma mune yakanyanya kunaka mhando monocrystalline silicon ingot.
