Igikoresho cya Semiconductor nicyo shingiro ryibikoresho bigezweho byimashini zinganda, bikoreshwa cyane muri mudasobwa, ibikoresho bya elegitoroniki y’abaguzi, itumanaho ry’urusobe, ibikoresho bya elegitoroniki, hamwe n’ibindi bice by’ibanze, inganda zikoresha imashini zigizwe ahanini n’ibice bine by’ibanze: imiyoboro ihuriweho, ibikoresho bya optoelectronic, ibikoresho byihariye, sensor, bingana na 80% by’umuzunguruko uhuriweho, cyane cyane hamwe na semiconductor hamwe.
Umuzunguruko wuzuye, ukurikije icyiciro cyibicuruzwa bigabanijwemo ibyiciro bine: microprocessor, kwibuka, ibikoresho bya logique, ibice byigana. Ariko, hamwe no kwaguka kwaguka kwimyanya ikoreshwa ryibikoresho bya semiconductor, ibihe byinshi bidasanzwe bisaba imiyoboro ya semiconductor kugirango ibashe gukurikiza ikoreshwa ryubushyuhe bwo hejuru, imirasire ikomeye, ingufu nyinshi nibindi bidukikije, ntibishobora kwangiza, igisekuru cya mbere nicyakabiri cyibikoresho bya semiconductor nta mbaraga bifite, nuko igisekuru cya gatatu cyibikoresho bya semiconductor byaje kubaho.
Kugeza ubu, ibikoresho bigari bya semiconductor ibikoresho byerekanwe nasilicon karbide. Igisekuru cya gatatu cyibikoresho bya semiconductor hamwe nubugari bwagutse bwagutse, hejuru yumuriro wumuriro wamashanyarazi, ubushyuhe bwumuriro, umuvuduko wuzuye wa elegitoronike hamwe nubushobozi buhanitse bwo kurwanya imirasire, bikwiranye no gukora ubushyuhe bwinshi, inshuro nyinshi, kurwanya imirasire hamwe nibikoresho bikoresha ingufu nyinshi, ubusanzwe bizwi nkibikoresho bigari bya semiconductor (ubugari bwumubyimba urenze hejuru ya 2.2 eV). Duhereye ku bushakashatsi buriho ku bikoresho bya semiconductor yo mu gisekuru cya gatatu, ibikoresho bya silicon karbide na gallium nitride ibikoresho bya semiconductor birakuze, kandisilicon carbide tekinorojini ikuze cyane, mugihe ubushakashatsi kuri zinc oxyde, diyama, nitride ya aluminium nibindi bikoresho biracyari mubyiciro byambere.
Ibikoresho n'imiterere yabyo ：
Carbideibikoresho bikoreshwa cyane mubitereko byumupira wumubumbyi, indangagaciro, ibikoresho bya semiconductor, giros, ibikoresho byo gupima, ikirere nizindi nzego, byahindutse ibikoresho bidasubirwaho mubikorwa byinshi byinganda.
SiC ni ubwoko bwa superlattice karemano hamwe na polytype isanzwe. Hariho imiryango irenga 200 (kuri ubu izwi) homotypic polytypic imiryango bitewe nuburyo butandukanye bwo gupakira ibintu hagati ya diatomic ya Si na C, biganisha kubintu bitandukanye bya kristu. Kubwibyo, SiC irakwiriye cyane kubisekuru bishya byumucyo usohora diode (LED) ibikoresho byububiko, ibikoresho bya elegitoroniki bikomeye.

umutungo wa shimi | Kurwanya ruswa cyane, irwanya hafi ikintu cyose kizwi cyangirika mubushyuhe bwicyumba |
| Ubuso bwa SiC bworoshye okiside kugirango ikore SiO, igicucu cyoroshye, irashobora gukumira okiside yayo, muri Hejuru ya 1700 ℃, firime ya oxyde irashonga kandi igahinduka vuba | |
| Igipande cya 4H-SIC na 6H-SIC nikubye inshuro 3 icya Si ninshuro 2 za GaAs: Kumeneka amashanyarazi yamashanyarazi ni gahunda yubunini burenze Si, kandi umuvuduko wa electron umuvuduko wuzuye Inshuro ebyiri nigice Si. Igipande cya 4H-SIC ni kinini kuruta icya 6H-SIC |
