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

Incazelo emfushane:

Ngokuthuthuka kwesayensi nobuchwepheshe, izidingo ezintsha zobukhulu kanye nekhwalithi yezinto zekristalu yesafire zibekwe phambili. Manje, ngokuthuthuka okusheshayo kokukhanyisa kwe-semiconductor nezinye izinhlelo zokusebenza ezivelayo, imakethe yezindleko eziphansi, ikhwalithi ephezulu, amakristalu amakhulu esafire akhula ngendlela emangalisayo.

12inch Sapphire Substrate Market Situation

Njengamanje, isafire inezinhlobo ezimbili eziyinhloko ezisetshenziswayo, enye i-substrate material, okuyizinto ezibonakalayo ze-LED substrate, enye iwashi lokudayela, ukuhamba kwezindiza, i-aerospace, impahla ekhethekile yokukhiqiza iwindi.

Nakuba i-silicon carbide, i-silicon ne-gallium nitride nazo ziyatholakala njengama-substrates ama-led ngaphezu kwesafire, ukukhiqizwa ngobuningi akukakwazi ngenxa yezindleko nezinye izingqinamba zobuchwepheshe ezingaxazululiwe. I-Sapphire substrate ngokuthuthuka kobuchwepheshe eminyakeni yamuva nje, ukufanisa i-lattice yayo, ukuqhutshwa kukagesi, izakhiwo zemishini, ukuqhutshwa kwe-thermal kanye nezinye izakhiwo kuye kwathuthukiswa kakhulu futhi kwakhuthazwa, inzuzo engabizi ibalulekile, ngakho-ke isafire isiphenduke into evuthwe kakhulu futhi ezinzile ye-substrate. embonini ye-LED, isetshenziswe kabanzi emakethe, isabelo semakethe sifinyelela ku-90%.

Isici Se-Substrate ye-Sapphire Wafer engu-12 Intshi

1. Izindawo zeSapphire substrate zinenani eliphansi kakhulu lezinhlayiya, ezinezinhlayiya ezingaphansi kuka-50 ama-microns angu-0.3 noma ngaphezulu ngamayintshi angu-2 kusayizi wamayintshi angu-2 ukuya kwangu-8, nezinsimbi ezinkulu (K, Ti, Cr, Mn, Fe, Co, Ni , Cu, Zn) ngaphansi kuka-2E10/cm2. Izinto eziyisisekelo ezingama-intshi angu-12 nazo kulindeleke ukuthi zifinyelele kuleli banga.
2. Ingasetshenziswa njenge-wafer yenkampani yenqubo yokukhiqiza ye-semiconductor engu-12-intshi (amaphalethi okuthutha angaphakathi kudivayisi) nanjenge-substrate yokubopha.
3. Ingakwazi ukulawula ukuma kwe-concave kanye ne-convex surface.
Indwangu: Ikristalu eyodwa ecwebile i-Al2O3, isicwecwana sesafire.
Ikhwalithi ye-LED, awekho amabhamuza, imifantu, amawele, uhlu lozalo, awukho umbala..etc.
