200mm 8inch GaN pa gawo la safiro la Epi-layer wafer
Chiyambi cha malonda
Gawo la GaN-on-Sapphire la mainchesi 8 ndi chinthu chapamwamba kwambiri cha semiconductor chomwe chimapangidwa ndi Gallium Nitride (GaN) layer yomwe imamera pa gawo la Sapphire. Chida ichi chili ndi mphamvu zabwino kwambiri zoyendera zamagetsi ndipo ndi choyenera kupanga zida za semiconductor zamphamvu kwambiri komanso zama frequency apamwamba.
Njira Yopangira
Njira yopangira zinthu imaphatikizapo kukula kwa epitaxial kwa gawo la GaN pa gawo la Sapphire pogwiritsa ntchito njira zapamwamba monga metal-organic chemical vapor deposition (MOCVD) kapena molecular beam epitaxy (MBE). Kuyika kumeneku kumachitika pansi pa mikhalidwe yolamulidwa kuti zitsimikizire kuti kristalo ndi filimu ndi yofanana.
Mapulogalamu
Gawo la GaN-on-Sapphire la mainchesi 8 limagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana kuphatikiza kulumikizana kwa ma microwave, ma radar system, ukadaulo wopanda zingwe, ndi ma optoelectronics. Zina mwa ntchito zomwe zimagwiritsidwa ntchito kwambiri ndi izi:
1. Zokulitsa mphamvu za RF
2. Makampani owunikira a LED
3. Zipangizo zolumikizirana ndi netiweki zopanda zingwe
4. Zipangizo zamagetsi zogwiritsira ntchito malo otentha kwambiri
5. Ozipangizo zamagetsi
Zofotokozera Zamalonda
-Muyeso: Kukula kwa gawo lapansi ndi mainchesi 8 (200 mm) m'mimba mwake.
- Ubwino wa pamwamba: Pamwamba pake pamakhala posalala kwambiri ndipo pamakhala mawonekedwe abwino kwambiri ngati galasi.
- Kukhuthala: Kukhuthala kwa gawo la GaN kungasinthidwe malinga ndi zofunikira zinazake.
- Kupaka: Choyikacho chimayikidwa mosamala mu zinthu zotsutsana ndi static kuti zisawonongeke panthawi yoyenda.
- Kulunjika Kosalala: Pansi pake pali malo olunjika enieni kuti athandize kulinganiza ndi kusamalira ma wafer panthawi yopanga chipangizocho.
- Magawo ena: Mafotokozedwe enieni a makulidwe, kukana, ndi kuchuluka kwa dopant akhoza kusinthidwa malinga ndi zosowa za makasitomala.
Ndi mphamvu zake zapamwamba komanso kugwiritsa ntchito zinthu zosiyanasiyana, gawo la GaN-on-Sapphire la mainchesi 8 ndi chisankho chodalirika pakupanga zida zapamwamba kwambiri zama semiconductor m'mafakitale osiyanasiyana.
Kupatula GaN-On-Sapphire, tithanso kupereka ntchito zokhudzana ndi zida zamagetsi, gulu la zinthu limaphatikizapo ma wafer a epitaxial a mainchesi 8 a AlGaN/GaN-on-Si ndi ma wafer a epitaxial a P-cap a mainchesi 8 a AlGaN/GaN-on-Si. Nthawi yomweyo, tidapanga njira yatsopano yogwiritsira ntchito ukadaulo wake wapamwamba wa 8-inch GaN epitaxy m'munda wa microwave, ndikupanga wafer wa epitaxy wa mainchesi 8 wa AlGaN/GAN-on-HR Si epitaxy womwe umaphatikiza magwiridwe antchito apamwamba ndi kukula kwakukulu, mtengo wotsika komanso wogwirizana ndi makina ogwiritsira ntchito a mainchesi 8. Kuphatikiza pa gallium nitride yochokera ku silicon, tilinso ndi mzere wazinthu za AlGaN/GaN-on-SiC epitaxial wafers kuti akwaniritse zosowa za makasitomala pazinthu za gallium nitride epitaxial zochokera ku silicon.
