12 inchi Dia300x1.0mmt Sapphire Wafer Substrate C-Plane SSP/DSP

12 inch Dia300x1.0mmt Sapphire Wafer Substrate C-Plane SSP/DSP Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ndi chitukuko cha sayansi ndi zamakono, zofunikira zatsopano za kukula ndi khalidwe la zipangizo za safiro za safiro zayikidwa patsogolo. Tsopano, ndikukula mwachangu kwa kuyatsa kwa semiconductor ndi ntchito zina zomwe zikubwera, msika wamtengo wotsika, wapamwamba kwambiri, makhiristo akulu a safiro ukukulirakulira.

12inch Sapphire Substrate Market Situation

Pakalipano, safiro ili ndi ntchito ziwiri zazikulu, imodzi ndi gawo lapansi, lomwe makamaka ndi gawo lapansi la LED, lina ndi loyimba wotchi, ndege, mlengalenga, zida zapadera zopangira zenera.

Ngakhale silicon carbide, silicon ndi gallium nitride ziliponso ngati magawo a ma LED kuphatikiza safiro, kupanga misala sikungatheke chifukwa cha mtengo komanso zovuta zina zaukadaulo zomwe sizinathe. Sapphire gawo lapansi kudzera mu chitukuko chaukadaulo m'zaka zaposachedwa, mafananidwe ake a lattice, madulidwe amagetsi, makina amakina, matenthedwe matenthedwe ndi zinthu zina zasinthidwa kwambiri ndikulimbikitsidwa, zotsika mtengo ndizofunika, kotero safiro yakhala chinthu chokhwima kwambiri komanso chokhazikika cha gawo lapansi pamakampani a LED, chakhala chikugwiritsidwa ntchito kwambiri pamsika, gawo la msika ngati 90%.

Makhalidwe A 12 Inchi Sapphire Wafer Substrate

1. Malo a safiro ali ndi tinthu tating'ono kwambiri, tochepa 50 particles 0.3 microns kapena zazikulu pa mainchesi 2 mu kukula kwa 2 mpaka 8 inchi, ndi zitsulo zazikulu (K, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn) pansi pa 2E10 / cm2. Zida zoyambira 12-inch zikuyembekezekanso kukwaniritsa giredi iyi.
2. Ikhoza kugwiritsidwa ntchito ngati chonyamulira chonyamulira cha 12-inch semiconductor kupanga ndondomeko (pallets zoyendera mu chipangizo) komanso ngati gawo lapansi la mgwirizano.
3. Imatha kuwongolera mawonekedwe a concave ndi pamwamba pa convex.
Zakuthupi: Kuyera kwakukulu kofanana ndi kristalo Al2O3, nsalu ya safiro.
Ubwino wa LED, palibe thovu, ming'alu, mapasa, mzere, palibe mtundu..etc.
