SiO2 Thin Film Thermal Oxide Silicon wafer 4inch 6inch 8inch 12inch
Kuwonetsa bokosi la wafer
Njira yayikulu yopangira ma wafer a silicon oxidized nthawi zambiri imakhala ndi magawo otsatirawa: kukula kwa silicon monocrystalline, kudula ma wafer, kupukuta, kuyeretsa ndi kusungunuka.
Kukula kwa silicon imodzi yokha: Choyamba, silicon imodzi yokha imakula kutentha kwambiri pogwiritsa ntchito njira monga njira ya Czochralski kapena njira ya Float-zone. Njirayi imalola kukonzekera makristalo amodzi a silicon okhala ndi chiyero chapamwamba komanso umphumphu wa lattice.
Kudula: Silikoni ya monocrystalline yomwe yakula nthawi zambiri imakhala yozungulira ndipo imafunika kudulidwa kukhala ma wafers opyapyala kuti igwiritsidwe ntchito ngati wafer substrate. Kudula nthawi zambiri kumachitika ndi chodulira cha diamondi.
Kupukuta: Pamwamba pa wafer wodulidwayo pakhoza kukhala kosiyana ndipo pamafunika kupukuta ndi mankhwala kuti pakhale malo osalala.
Kuyeretsa: Wafer wopukutidwa umatsukidwa kuti uchotse zinyalala ndi fumbi.
Kusakaniza: Pomaliza, ma wafer a silicon amaikidwa mu uvuni wotentha kwambiri kuti agwiritsidwe ntchito ngati okosijeni kuti apange gawo loteteza la silicon dioxide kuti liwongolere mphamvu zake zamagetsi ndi mphamvu zake zamakanika, komanso kuti likhale ngati gawo loteteza kutentha m'mabwalo ophatikizika.
Ntchito zazikulu za ma wafer a silicon oxidized ndi monga kupanga ma circuits ophatikizidwa, kupanga ma solar cell, ndi kupanga zida zina zamagetsi. Ma wafer a silicon oxide amagwiritsidwa ntchito kwambiri pakupanga zinthu za semiconductor chifukwa cha makhalidwe awo abwino a makina, kukhazikika kwa mawonekedwe ndi mankhwala, kuthekera kogwira ntchito kutentha kwambiri komanso kupsinjika kwakukulu, komanso mphamvu zabwino zotetezera kutentha ndi kuwala.
Ubwino wake ndi monga kapangidwe kake ka kristalo, kapangidwe kake ka mankhwala, kukula kwake kolondola, mphamvu zake zabwino zamakaniko, ndi zina zotero. Zinthu zimenezi zimapangitsa kuti ma wafer a silicon oxide akhale oyenera kwambiri popanga ma circuits ophatikizidwa bwino komanso zida zina zamagetsi.
