ʻO SiC Ceramic Crucible

Hana ʻia ka SiC Ceramic Crucible ma ke ʻano he kīʻaha koʻikoʻi a me ka moku pane i nā kaʻina hana e like me ka ulu ʻana o ka kristal SiC a me GaN, ka epitaxial deposition, diffusion, a me ka annealing kiʻekiʻe-ma kahi e hoʻoholo pololei ai ka maʻemaʻe, kūpaʻa, a me ke kūlike o ka mahana i ka hua wafer a me ka maikaʻi kristal.

Nā Mea Pono Mea Pono

● Mea Hana: Ultra-maʻemaʻe sintered SiC a CVD-SiC (≥99.9%)

● Density & Microstructure: ʻOi aku ka paʻa paʻa, ʻili maikaʻi, a me ka porous ʻole no ka maikaʻi ʻole o ke kinoea.

● Paʻa Thermal: Hana maikaʻi loa a hiki i ka 2000°C i loko o nā ea kinoea inert a reactive.

● ʻO ka hoʻokō wela: 120–200 W/m·K, e hōʻoia ana i ka like ʻana o ka mahana.

● Paʻa ʻino: Paʻa loa i loko o ka hydrogen, chlorine, a me nā kinoea kaʻina hana halogen.

● Hoʻopau i ka ʻili: Hoʻomaʻemaʻe ʻia i ka aniani a hoʻomaʻemaʻe ʻia i ka plasma e hōʻemi i ka hana ʻana o nā ʻāpana

Nā noi nui ma ka hana semiconductor

He kuleana koʻikoʻi ka SiC Ceramic Crucible i kekahi mau hana hana semiconductor, me:

1. Ka ulu ʻana o ka Crystal a me ka Epitaxy

Hoʻohana ʻia ma PVT (Physical Vapor Transport) a me nā ʻōnaehana ulu epitaxial CVD, hāʻawi ʻo SiC crucibles i kahi pahu paʻa, non-reactive no nā kumu kumu a me nā kristal ulu.

ʻO kā lākou maʻemaʻe kiʻekiʻe a me ka hoʻohālikelike ʻana i ka hoʻonui ʻana i ka wela e hōʻemi i ka haumia a me ke koʻikoʻi, e hōʻoia ana i ka hoʻokumu ʻia ʻana o ke aniani kīnā ʻole no nā substrate SiC, GaN, a me Ga₂O₃.

2. Kiʻekiʻe-Menahana Diffusion a Annealing

I ka mālama ʻana i ka wela, ka laha ʻana, a me nā kaʻina hana hoʻokahe, mālama ʻo SiC crucibles i ko lākou ʻano a me ka kūpaʻa kemika ma lalo o ke kaʻa uila wela loa, e pale ana i ka hoʻokuʻu ʻana a me ka hoʻokuʻu ʻana i nā mea hiki ke hoʻololi i ka maikaʻi o ka wafer.

3. Mea Sintering a me ka pauda

He mea maikaʻi nō hoʻi ʻo SiC crucibles no ka semiconductor-grade powder sintering, e hāʻawi ana i ka inertness kemika kiʻekiʻe a me ke kūpaʻa dimensional ma lalo o ka vacuum a i ʻole ke kūlana lewa.

Nā Pono o Semixlab

Ma Semixlab Semiconductor, hāʻawi mākou i ʻoi aku ma mua o nā ʻāpana wale nō - hāʻawi mākou i nā hoʻonā ʻenehana piha e hoʻokō i nā koi koʻikoʻi o ka hana semiconductor.

1. Hoʻolālā Kūpono

● Hoʻonohonoho ʻia ke ʻano geometry, mānoanoa, a me ke kinoea.

● Hoʻohālikelike me ka ulu kristal nui a me nā ʻōnaehana CVD (LPE, PVT, AIXTRON, Veeco, etc.).

2. Kūkākūkā ʻenehana

● ʻO nā mea ʻepekema a me nā ʻenekini kaʻina hana i loko o ka hale me nā makahiki he 20 o ka ʻoihana.

● Kākoʻo no ka hoʻolālā wela, ka hoʻoheheʻe kinoea, a me ke kaʻina hana.

3. Mamua o ka ho'ouna 'ana i ka maika'i hō'oia

● Loaʻa i kēlā me kēia crucible ka nānā pono ʻana, ka hoʻāʻo ʻana o ka helium leak, a me ka nānā ʻana o ka ʻili.

● ʻO ka uhi pale CVD koho a me nā lawelawe hoʻoliʻi aniani no ka hoʻonui ʻana i ke ola a me ka maʻemaʻe.

Hoʻonohonoho ka Semixlab SiC Ceramic Crucible i kahi hōʻailona hou no ka paʻa ʻana o ka wela, ka maʻemaʻe, a me ka lōʻihi o ke kemika i ka hana semiconductor holomua. Me nā koho hoʻolālā maʻamau, kūkākūkā ʻenehana, a me ka nānā ʻana ma mua o ka hoʻouna ʻana, hōʻoia ʻo Semixlab i kēlā me kēia huahana e hoʻokō i nā koi koi o nā noi semiconductor kiʻekiʻe-maʻemaʻe. Ke kali nei mākou i kāu mau nīnau hou.
