Xudunta Dhoobada Alumina ee Nadiifka Sare leh ee Qalabka Semiconductor-ka
Xudunta dhoobada alumina ee St.Cera waxaa laga sameeyay 99.8% saafinimo sare leh oo Al₂O₃ ah, taasoo bixisa xoog dielectric oo heer sare ah (15×10⁶ V/m), xasillooni kuleyl ilaa 1600°C, iyo iska caabin gurguurta oo culays saaran. Xuduntan waxaa loo isticmaalaa qaybo qaab-dhismeed ahaan qalabka heerkulka sare, saldhigyada kuleyliyaha, dahaarka qolka plasma, iyo dahaarka korontada. Adkeysiga sare ee walxaha (16 GPa) iyo nuugista biyaha oo hooseeya (0%) waxay hubiyaan isku halaynta muddada dheer ee jawiyada adag.

Codsiyada:
- · Xudunta kuleyliyaha ee fal-galayaasha epitaxial
- · Dahaarka qolka balaasmaha iyo saxannada daboolka
- · Dareeraha korontada ee danab sare leh
- · Saldhigga qalabka ee robotyada maaraynta wafer-ka
Wax soo saarka:
Riixitaanka Isostatic → mashiinka cagaaran → sintering heerkul ah 1600°C → CNC shiidi ilaa cabbirrada ugu dambeeya (dulqaad ±0.01 mm). Xuddun kasta waxaa lagu baadhaa CMM iyo ogaanshaha cilladaha ultrasonic.
Hubinta Tayada:
Shahaadada ISO 9001: 2015. Tijaabada gelinta rinjiga ee dildilaaca dusha sare; tijaabada xoogga dielectric sida waafaqsan ASTM D149.
Afaa'iidooyinka ka badan dhoobada kale:
- · Awood dielectric oo ka sareysa zirconia (15 vs <10×10⁶ V/m)
- · Kharash ka hooseeya SiC ee codsiyada aan ahayn plasma
- · Iska caabin kiimiko oo aad u fiican oo loogu talagalay halogens (marka laga reebo HF)
Qaababka Gaarka ah:
Dhululubo, baararka laba jibbaaran, saxanno, ama joomatari isku dhafan. Cabbirka ugu yar ee astaamaha 0.5 mm.
