SiO2 Sirin Fim Mai Zafi Mai Zafi Wafer Silikon 4 inci 6 inci 8 inci 12

Babban tsarin ƙera wafers ɗin silicon da aka yi wa oxidized yawanci ya haɗa da waɗannan matakai: haɓakar silicon monocrystalline, yanke wafers, gogewa, tsaftacewa da kuma oxidation.

Girman silicon mai siffar monocrystalline: Da farko, ana shuka silicon mai siffar monocrystalline a yanayin zafi mai yawa ta hanyoyi kamar hanyar Czochralski ko hanyar Float-zone. Wannan hanyar tana ba da damar shirya lu'ulu'u guda ɗaya na silicon tare da tsarki mai yawa da kuma ingancin lattice.

Yanka: Silikon monocrystalline da aka girma yawanci yana da siffar silinda kuma yana buƙatar a yanka shi zuwa siririn wafers don amfani da shi azaman substrate na wafer. Yawanci ana yanke shi da mai yanke lu'u-lu'u.

Gogewa: Fuskar wafer ɗin da aka yanke na iya zama mara daidaito kuma yana buƙatar gogewa ta hanyar sinadarai da injiniya don samun santsi.

Tsaftacewa: Ana tsaftace wafer ɗin da aka goge don cire ƙazanta da ƙura.

Oxidizing: A ƙarshe, ana saka wafers ɗin silicon a cikin tanda mai zafi don maganin oxidizing don samar da Layer na kariya na silicon dioxide don inganta halayen wutar lantarki da ƙarfin injina, da kuma yin aiki a matsayin Layer mai rufewa a cikin da'irori masu haɗawa.

Babban amfani da wafers ɗin silicon da aka yi wa oxidized sun haɗa da ƙera da'irori masu haɗawa, ƙera ƙwayoyin hasken rana, da kuma ƙera wasu na'urorin lantarki. Ana amfani da wafers ɗin silicon oxide sosai a fannin kayan semiconductor saboda kyawawan halayen injiniya, daidaiton girma da sinadarai, ikon aiki a yanayin zafi mai yawa da matsin lamba mai yawa, da kuma kyawawan kaddarorin rufewa da gani.

Fa'idodinsa sun haɗa da cikakken tsarin lu'ulu'u, tsantsar sinadaran sinadarai, daidaiton girma, kyawawan halayen injiniya, da sauransu. Waɗannan fasalulluka suna sa wafers ɗin silicon oxide su dace musamman don ƙera da'irori masu aiki da sauran na'urorin lantarki masu ƙarfi.
