Silicon karbide substrate igabanijwemo ubwoko bwa-insuline nubwoko butwara. Kugeza ubu, ibyingenzi byerekana ibicuruzwa bya silicon karbide substrate yibicuruzwa ni santimetero 4. Mumasoko ya silicon karbide yisoko, ibyingenzi byingenzi byibanze byibicuruzwa ni santimetero 6.
Bitewe no kumurongo wo hasi murwego rwa RF, insimburangingo ya SiC yubatswe hamwe nibikoresho bya epitaxial bigomba kugenzurwa na minisiteri yubucuruzi yo muri Amerika. Semi-insulasiyo ya SiC nka substrate nibikoresho byatoranijwe kuri GaN heteroepitaxy kandi ifite ibyifuzo byingenzi byo gukoresha mumashanyarazi ya microwave. Ugereranije na kristu idahuye ya safiro 14% na Si 16.9%, kudahuza kristu kubikoresho bya SiC na GaN ni 3.4% gusa. Hamwe na ultra-high yumuriro wa SiC, ingufu nyinshi LED na GaN inshuro nyinshi hamwe nibikoresho bya microwave nini byateguwe na byo bifite ibyiza byinshi muri radar, ibikoresho bya microwave nini na sisitemu yo gutumanaho 5G.
Ubushakashatsi niterambere byigice cya insuline ya SiC yamye yibandwaho mubushakashatsi niterambere rya SiC imwe ya kristu. Hariho ingorane zibiri nyamukuru mukuzamura ibikoresho bya SiC byiganjemo:

Kugeza ubu, abayikora bafite ubushobozi bwo gukora SiC igice cya kabiri ni SICC Co ， Semisic Crystal Co ， Tanke Blue Co, Hebei Synlight Crystal Co., Ltd.
Kirisiti ya SiC itwara abantu igerwaho no gutera azote mu kirere gikura. Amashanyarazi ya silicon karbide substrate akoreshwa cyane cyane mugukora ibikoresho byamashanyarazi, ibikoresho bya silikoni ya karbide ifite ingufu nyinshi, umuyaga mwinshi, ubushyuhe bwinshi, inshuro nyinshi, igihombo gito nibindi byiza bidasanzwe, bizamura cyane imikoreshereze ihari yingufu zikoresha ingufu za silicon guhindura imikorere, bifite ingaruka zikomeye kandi zigera kure murwego rwo guhindura ingufu neza. Ahantu ho gukoreshwa ni ibinyabiziga byamashanyarazi / ibirundo byo kwishyuza, ingufu za Photovoltaque nshya, inzira ya gari ya moshi, gride yubwenge nibindi. Kuberako epfo yibicuruzwa bitwara cyane cyane ibikoresho byamashanyarazi mumodoka yamashanyarazi, Photovoltaque nizindi nzego, ibyifuzo byo gusaba ni binini, kandi nababikora ni benshi.
Ubwoko bwa kiriside ya silicon: Imiterere isanzwe ya karibide nziza ya 4H ya kristaline ya silicon irashobora kugabanywamo ibyiciro bibiri, kimwe ni cubic silicon carbide kristal ubwoko bwa sphalerite, izwi nka 3C-SiC cyangwa β-SiC, naho ubundi ni mpande esheshatu cyangwa diyama imiterere yigihe kinini cyimiterere, isanzwe ya 6H-SiC, 4H-sic, 15R-SiC, nibindi, hamwe bizwi nka α-SiC. 3C-SiC ifite ibyiza byo guhangana cyane mubikoresho byo gukora. Ariko, kudahuza cyane hagati ya lattice ya Si na SiC hamwe na coefficient zo kwagura ubushyuhe birashobora gutuma habaho inenge nyinshi mubice 3C-SiC epitaxial. 4H-SiC ifite imbaraga nyinshi mugukora MOSFETs, kubera ko imikurire yacyo ya kirisiti hamwe niterambere ryikwirakwizwa rya epitaxial nibyiza cyane, kandi kubijyanye na moteri ya electron, 4H-SiC irenze 3C-SiC na 6H-SiC, itanga ibiranga microwave nziza kuri 4H -SOS MOSFETS.
Niba hari ihohoterwa, hamagara gusiba
