12 inch Silicon Wafer for Semiconductor Fabrication oo ay bixiso VET Energy waxaa loo habeeyay si loo buuxiyo heerarka saxda ah ee looga baahan yahay warshadaha semiconductor. Sida mid ka mid ah alaabooyinka hormuudka ka ah safkayaga, VET Energy waxay hubisaa in waferradan lagu soo saaro si qumman, nadiif ah, iyo tayada dusha sare, taasoo ka dhigaysa inay ku habboon yihiin codsiyada semiconductor-ka gees-goynta ah, oo ay ku jiraan microchips, dareemayaasha, iyo aaladaha elektiroonigga ah ee horumarsan.
Waferkan waxa uu la jaan qaadayaa agabyo kala duwan oo ay ka mid yihiin Si Wafer, Substrate SiC, SOI Wafer, SiN Substrate, iyo Epi Wafer, taas oo bixisa kala duwanaansho heersare ah oo loogu talagalay hababka kala duwan ee wax-soo-saarka. Intaa waxaa dheer, waxay si fiican ula mid tahay tignoolajiyada horumarsan sida Gallium Oxide Ga2O3 iyo AlN Wafer, iyadoo hubinaysa in lagu dhex dari karo codsiyada khaaska ah. Si loo fududeeyo hawlgalka, waferka waxaa loo habeeyay in lagu isticmaalo nidaamyada cajaladaha heerka warshadaha, iyadoo la hubinayo in si hufan loogu maareeyo wax soo saarka semiconductor.
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.
Goobaha codsiga:
•Chips macquul ah:Soo saarista chips-ka macquulka ah ee waxqabadka sare leh sida CPU iyo GPU.
•Xirmooyinka xusuusta:Soo-saarista chip-yada xusuusta sida DRAM iyo NAND Flash.
•Analog chips:Soo saarida chips-ka analoogga ah sida ADC iyo DAC.
•Dareemayaasha:Dareemayaasha MEMS, dareemayaasha sawirka, iwm.
Tamarta VET waxay siisaa macaamiisha xalal loo habeeyey, waxayna u habayn kartaa waferrada leh iska caabin kala duwan, oksijiin kala duwan, dhumuc kala duwan iyo tilmaamo kale iyadoo loo eegayo baahiyaha gaarka ah ee macaamiisha. Intaa waxaa dheer, waxaan sidoo kale bixinnaa taageero farsamo oo xirfad leh iyo adeegga iibka ka dib si aan uga caawino macaamiisha inay wanaajiyaan hababka wax soo saarka iyo horumarinta wax soo saarka alaabta.
