Usha Goobta Dhoobada Alumina ee Saxda ah ee loogu talagalay Qalabka Semiconductor-ka
Usha goobta dhoobada ah ee St.Cera waa mid si sax ah loo shiiday laga bilaabo 99.8% alumina saafi ah oo sareysa (Al₂O₃). Waxay bixisaa adkeysi sare (16 GPa), iska caabin heer sare ah oo xirasho, iyo xasillooni cabbir. Dulqaad dhexroorku waa mid adag sida ±0.005 mm, dhererkiisuna waa ilaa 150 mm. Dusha sare ee usha waxaa lagu dhejiyaa Ra ≤0.2 μm si loogu dhejiyo loona saaro si siman. Waxaa loo isticmaalaa sida biinanka isku-xidhka, biinanka dowel, ama joojinta meelaynta qalabka habka semiconductor-ka, cajaladaha wafer-ka, iyo qalabka kormeerka.
