VET Energy wafers silikoon oo 8-inch ah ayaa si weyn loogu isticmaalaa korantada elektiroonigga ah, dareemayaasha, wareegyada isku dhafan iyo meelaha kale. Hogaamiye ahaan warshadaha semiconductor, waxaa naga go'an inaan bixino alaab tayo sare leh Si Wafer si aan u daboolno baahiyaha sii kordhaya ee macaamiisheena.
Marka lagu daro Si Wafer, VET Energy waxa kale oo ay bixisaa noocyo badan oo ah qalabka substrate-ka, oo ay ku jiraan SiC Substrate, SOI Wafer, SiN Substrate, Epi Wafer, iwm Wafer, siinta taageero xooggan horumarinta qalabka korontada ee jiilka soo socda.
VET Energy waxay leedahay qalab wax soo saar horumarsan iyo nidaam maarayn tayo oo dhamaystiran si loo hubiyo in wafer kastaa la kulmo heerarka adag ee warshadaha. Alaabtayadu maaha oo kaliya inay leeyihiin sifooyin koronto oo aad u fiican, laakiin sidoo kale waxay leeyihiin awood farsamo oo wanaagsan iyo xasilloonida kulaylka.
Tamarta VET waxa ay siisaa macaamiisha xalalka wafer-ga la habeeyey, oo ay ku jiraan maraqyada cabbirrada kala duwan, noocyada iyo uruurinta doping-ka. Intaa waxaa dheer, waxaan sidoo kale ku siin taageero farsamo xirfadeed iyo adeegga iibka ka dib si ay u caawiyaan macaamiisha xaliyaan dhibaatooyin kala duwan oo la kulmay inta lagu guda jiro habka wax soo saarka.
