Monocrystalline 8 inch Silicon Wafer ka VET Energy waa xalka warshadaha hogaaminaya ee soo saarista qalabka elektiroonigga ah. Bixinta nadiifinta sare iyo qaab-dhismeedka crystalline, waferradani waxay ku habboon yihiin codsiyada waxqabadka sare leh ee labadaba warshadaha sawir-qaadista iyo semiconductor. Tamarta VET waxay hubisaa in wafer kasta si taxadar leh loo habeeyey si loo buuxiyo heerarka ugu sarreeya, iyadoo bixisa labis heer sare ah iyo dhammayn siman oo dusha sare ah, kuwaas oo lama huraan u ah soo saarista aaladaha elektiroonigga ah ee horumarsan.
Monocrystalline 8 Inch Silicon Wafers waxay la jaan qaadayaan agabyo kala duwan, oo ay ku jiraan Si Wafer, SiC Substrate, SOI Wafer, SiN Substrate, waxayna si gaar ah ugu habboon yihiin koritaanka Epi Wafer. Kuleylkooda sare ee kuleylka iyo guryaha korantada ayaa ka dhigaya doorasho lagu kalsoonaan karo oo wax soo saar sare leh. Intaa waxaa dheer, waferradan waxaa loogu talagalay inay si aan kala go 'lahayn ugu shaqeeyaan agabka ay ka midka yihiin Gallium Oxide Ga2O3 iyo AlN Wafer, iyagoo bixiya codsiyo kala duwan oo laga soo bilaabo korantada korantada ilaa aaladaha RF. Wafers-yadu waxay sidoo kale si fiican ugu habboon yihiin nidaamyada cajaladaha ee cabbirka sare, jawiga wax soo saarka otomaatiga ah.
Khadka wax soo saarka VET Energy kuma koobna waferrada silikoon. Waxa kale oo aanu bixinaa agabka substrate-ka ee kala duwan, oo ay ku jiraan SiC Substrate, SOI Wafer, SiN Substrate, Epi Wafer, iwm., iyo sidoo kale agabka cusub ee bandgap semiconductor sida Gallium Oxide Ga2O3 iyo AlN Wafer. Alaabooyinkani waxay dabooli karaan baahida codsiga macaamiisha kala duwan ee korontada, inta jeer ee raadiyaha, dareemayaasha iyo goobaha kale.
Tamarta VET waxay siisaa macaamiisha xalalka wafer ee la habeeyey. Waxaan astaysto karin sharoobada leh iska caabin kala duwan, content oxygen, dhumucdiisuna, iwm sida waafaqsan baahida gaarka ah ee macaamiisha. 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 kulmaan inta lagu guda jiro habka wax soo saarka.
