150mm 200mm 6 iniha 8 iniha GaN ma Silicon Epi-layer wafer Gallium nitride epitaxial wafer
Hana hana
ʻO ke kaʻina hana e pili ana i ka ulu ʻana i nā papa GaN ma kahi substrate sapphire me ka hoʻohana ʻana i nā ʻenehana holomua e like me ka metal-organic chemical vapor deposition (MOCVD) a i ʻole molecular beam epitaxy (MBE). Hana ʻia ke kaʻina hana deposition ma lalo o nā kūlana i hoʻopaʻa ʻia e hōʻoia i ka maikaʻi kristal kiʻekiʻe a me ke kiʻi like ʻole.
6inihi GaN-On-Sapphire noi: 6-inihi sapphire substrate chips i hoʻohana nui ʻia i ka microwave communications, radar system, wireless technology and optoelectronics.
Aia kekahi mau noi maʻamau
1. Rf mana hoonui
2. ʻOihana kukui LED
3. Nā lako kamaʻilio pūnaewele ʻole
4. ʻO nā mea uila ma ke ʻano wela kiʻekiʻe
5. Nā mea hana optoelectronic
Nā kikoʻī huahana
- Nui: ʻO ke anawaena substrate he 6 iniha (ma kahi o 150 mm).
- Ka maikaʻi o ka ʻili: Ua hoʻomaʻamaʻa maikaʻi ʻia ka ʻili e hāʻawi i ke ʻano aniani maikaʻi loa.
- Mānoanoa: Hiki ke hoʻololi ʻia ka mānoanoa o ka papa GaN e like me nā koi kikoʻī.
- Packaging: Hoʻopili maikaʻi ʻia ka substrate me nā mea anti-static e pale ai i ka pōʻino i ka wā o ka lawe ʻana.
- Nā ʻaoʻao hoʻonohonoho: Loaʻa i ka substrate nā kihi hoʻonohonoho kikoʻī e hoʻomaʻamaʻa i ka alignment a me ka hana i ka wā o ka hoʻomākaukau ʻana.
- Nā ʻāpana ʻē aʻe: Hiki ke hoʻoponopono ʻia nā ʻāpana kikoʻī e like me ka thinness, resistivity a me ka doping concentration e like me nā koi o ka mea kūʻai aku.
Me kā lākou mau waiwai waiwai a me nā noi like ʻole, ʻo 6-inch sapphire substrate wafers kahi koho hilinaʻi no ka hoʻomohala ʻana i nā mea hana semiconductor kiʻekiʻe i nā ʻoihana like ʻole.
