VET ENERGY, Uyobora manuafacturer wa CVD SIC ikozwe mubushinwa

Ibikoresho bihindura ejo hazaza

Carbide ya Silicon (SiC) nigikoresho gishya cya semiconductor. Carbide ya silicon ifite icyuho kinini (hafi inshuro 3 silikoni), imbaraga zikomeye zumurima (hafi inshuro 10 silicon), ubushyuhe bwinshi bwumuriro (hafi inshuro 3 silikoni). Nibintu byingenzi bizakurikiraho-igice cya semiconductor ibikoresho. Ibikoresho bya SiC bikoreshwa cyane mu nganda ziciriritse hamwe n’ifoto yizuba. By'umwihariko, suseptors ikoreshwa mugukura kwa epitaxial ya LED na Si imwe ya kirisiti ya kirisiti isaba gukoresha igifuniko cya SiC. Bitewe no kuzamuka kwinshi kwa LED mu kumurika no kwerekana inganda, hamwe niterambere rikomeye ryinganda ziciriritse,Igicuruzwa cya SiCibyiringiro nibyiza cyane.

GUSHYIRA MU BIKORWA

Isuku, Imiterere ya SEM, isesengura ryubunini bwaSiC

Ubuziranenge bwibikoresho bya SiC kuri grafite ukoresheje CVD bingana na 99,9995%. Imiterere yacyo ni fcc. Filime za SiC zishushanyije kuri grafite ni (111) yerekanwe nkuko bigaragara mu makuru ya XRD (Igishusho.1) yerekana ubwiza bwayo bwa kristu. Ubunini bwa firime ya SiC burasa cyane nkuko bigaragara ku gishushanyo cya 2.

SEM amakuru ya CVD SiC yoroheje, ubunini bwa kristu ni 2 ~ 1 Opm

Igishushanyo 2: imyenda yuburebure bwa firime ya SiC

Imiterere ya kristu ya firime ya CVD SiC ni isura ya cubic yubatswe, kandi icyerekezo cyo gukura kwa firime kiri hafi 100%

URUBUGA RWA CRYSTAL SILICON EPITAXIAL

Imikorere yibicuruzwa hamwe nibisabwa.

Carbide ya Silicon (SiC) yatwikiriweshingiro niryo shingiro ryiza rya kirisiti imwe ya kirisiti na GaN epitaxy, nicyo kintu cyibanze kigize itanura rya epitaxy. Shingiro nigikoresho cyingenzi cyibikoresho bya silicon ya monocrystalline kumirongo minini ihuriweho. Ifite isuku nyinshi, irwanya ubushyuhe bwinshi, irwanya ruswa, ubukana bwiza bwikirere nibindi bintu byiza biranga ibintu.

Gusaba ibicuruzwa no gukoresha

Igishushanyo mbonera cya graphite yo gukura kwa kristu imwe ya silicon epitaxial Ikwiranye nimashini za Aixtron, nibindi .Gutwika uburebure: 90 ~ 150umUmurambararo wa wafer ni 55mm.

Ibisobanuro birambuye

Ningbo VET Energy Technology Co., Ltd ni uruganda rukora ibice bya grafite, cyane cyane mugutezimbere ibikoresho bishya bya semiconductor no kwibanda kubushakashatsi niterambere ryububiko bwa SiC. Ibicuruzwa nyamukuru byuru ruganda ni siyose ikozwe na SiC yinganda za LED ninganda za silicon monocrystalline. Filime ya SiC ikoreshwa mu nganda za LED n'inganda za silikoni ya monocrystalline ni cubic phase, ifite imiterere ya lattice imwe na diyama, kandi ubukana bwayo ni bwiza nka diyama. Carbide ya silicon nikintu kinini cyakuze cyagutse cya semiconductor, kandi gifite ibyifuzo byinshi mubikorwa byinganda. Byongeye kandi, karbide ya silicon ifite ubushyuhe bwinshi, coefficente ntoya yo kwagura ubushyuhe, ubushyuhe bwo hejuru (hafi dogere selisiyusi 2700), hamwe no kurwanya ruswa. Ibicuruzwa bitwikiriye silicon karbide bikoreshwa cyane mu kirere, mu nganda zifotora, ingufu za kirimbuzi, gari ya moshi yihuta, amamodoka n’izindi nganda.
