FZ CZ Si wafer a cikin hannun jari 12inch Silicon wafer Prime ko Gwaji

Takaitaccen Bayani:

A 12 inch silicon wafer abu ne na bakin ciki semiconductor abu da ake amfani dashi a aikace-aikacen lantarki da haɗaɗɗun da'irori. Silicon wafers abubuwa ne masu mahimmanci a cikin samfuran lantarki gama gari kamar kwamfutoci, TV da wayoyin hannu. Akwai nau'ikan wafers kuma kowanne yana da takamaiman kaddarorin sa. Don fahimtar mafi dacewa da wafer silicon don wani aiki na musamman, ya kamata mu fahimci nau'ikan wafers iri-iri da dacewarsu.
