Biinanka Taageerada Dhoobada ee Qalabka Habka Semiconductor-ka
Biinanka taageerada dhoobada ah ee St.Cera (oo sidoo kale loo yaqaan biinanka kor u qaada ama biinanka taageerada) waxaa loo isticmaalaa qolalka habka semiconductor-ka si kor loogu qaado biinanka ama substrate-ka inta lagu jiro maaraynta, kululaynta, ama qaboojinta. Laga soo saaray 99.8% alumina ama nitride silicon, biinankani waxay bixiyaan xoog cadaadis sare leh, xasillooni kuleyl, iyo iska caabin kiimiko. Naqshadaynta cidhifka toosan ama fidsan waxay ka hortagtaa xoqidda wafer-ka.
Tilmaamaha(Alumina 99.8%):
| Hantida | Qiimaha |
| Alaab | 99.8% Al₂O₃ ama Si₃N₄ |
| Dhererka | 10 - 100 mm |
| Dhexroorka | 1 – 10 mm |
| Qaabka Caarada | Fidsan, gees ahaan wareegsan, fiiqan |
| Xoogga Cadaadiska (Al₂O₃) | >2000 MPa |
| Heerkulka ugu Sareeya ee Hawlgalka (Al₂O₃) | 1600°C |
| Dhammaadka Dusha Sare | La daboolay (Ra ≤0.4 μm) |
| Dulqaadka Dhexroorka | ±0.01 mm |
Codsiyada:
Biinanka kor u qaad qolalka CVD/PVD
Biinanka taageerada ee dubista saxanka kulul
Qaab-dhismeedka taageerada kaarka baaritaanka
Taageerada doonyaha foornada Quartz
Wax soo saarka:
Shiidi aan sax ahayn oo aan xarun lahayn oo OD ah → Shiidi dheeman oo ah astaanta caarada → Nadiifinta ultrasonic → Kormeer cabbir 100%.
Xakamaynta Tayada:
CMM dhererka/dhexroorka, isbarbardhigga indhaha ee radius-ka caarada, tijaabada culayska si loo xaqiijiyo xoogga cadaadiska (muunad aan kala sooc lahayn halkii qayb). Ma jiraan wax wasakh ah oo ferromagnetic ah (oo lagu xaqiijiyay magnet).
Faa'iidooyinka Biinanka Birta ama Quartz:
5 jeer cimri dheer marka loo eego birta aan miridhku lahayn
Ma jiro wasakhayn bir ah oo ku jirta qolka geeddi-socodka
Awood heerkul oo ka sarreysa quartz (1600°C vs 1100°C)
Dusha sare ee aan dhegdheg lahayn (dhejinta walxaha oo yaraatay)
Habayn:
Astaamaha caarada badan, saldhig dunaysan, ama usha qaloocan.
Waxaan sidoo kale bixinnaa biinanka SiC ee loogu talagalay deegaannada aadka u daran ee plasma.
