SILICON WAFER

SILICON WAFER

Kuva

Awaferni agace ka silicon hafi ya milimetero 1 z'ubugari ifite ubuso buringaniye cyane bitewe nuburyo bukenewe mubuhanga. Imikoreshereze ikurikira igena uburyo bwo gukura bwa kristu bugomba gukoreshwa. Mubikorwa bya Czochralski, kurugero, silicon polycrystalline irashonga hanyuma ikaramu yoroheje yimbuto ikaramu ikarishye muri silikoni yashongeshejwe. Imbuto ya kirisiti noneho irazunguruka kandi ikururwa buhoro buhoro hejuru. Colosus iremereye cyane, monocrystal, ibisubizo. Birashoboka guhitamo monocrystal ibiranga amashanyarazi wongeyeho uduce duto twa dopants-yera cyane. Crystal ikoporowe ikurikije ibisobanuro byabakiriya hanyuma igasukurwa hanyuma igabanywamo ibice. Nyuma yinyongera zinyuranye zibyara umusaruro, umukiriya yakira wafer yihariye mugupakira bidasanzwe, byemerera umukiriya gukoreshawaferako kanya mumurongo wacyo.

Muri iki gihe, igice kinini cya monocrystal ya silicon gihingwa ukurikije inzira ya Czochralski, ikubiyemo gushonga silikoni polycrystalline ifite isuku nyinshi muri hyperpure quartz ikomeye kandi ikongeramo dopant (mubisanzwe B, P, As, Sb). Imbuto yoroheje, monocrystalline imbuto ya kirisiti yinjizwa muri silikoni yashonze. Kinini nini ya CZ noneho ikura kuva muri kristu yoroheje. Kugena neza ubushyuhe bwa silicon yashongeshejwe no gutemba, kristu no kuzunguruka cyane, kimwe no gukurura umuvuduko wa kirisiti bivamo ingirakamaro ya monocrystalline silicon ingot.
