Nubwoko bushya bwibikoresho bya semiconductor, SiC ibaye ibikoresho byingenzi bya semiconductor mugukora ibikoresho bigufi bya optoelectronic ibikoresho, ubushyuhe bwo hejuru, ibikoresho birwanya imirasire hamwe nimbaraga zikomeye / ibikoresho bya elegitoroniki byimbaraga kubera imiterere myiza yumubiri na chimique kandi ibikoresho by'amashanyarazi. Cyane cyane iyo ushyizwe mubihe bikabije kandi bikaze, ibiranga ibikoresho bya SiC birenze kure ibyo bikoresho bya Si nibikoresho bya GaAs. Kubwibyo, ibikoresho bya SiC nubwoko butandukanye bwa sensor byabaye buhoro buhoro kimwe mubikoresho byingenzi, bigira uruhare runini kandi rwingenzi.
Ibikoresho bya SiC hamwe n’umuzunguruko byateye imbere byihuse kuva mu myaka ya za 1980, cyane cyane guhera mu 1989 igihe wafer ya mbere ya SiC substrate yinjira ku isoko. Mu bice bimwe na bimwe, nka diode itanga urumuri, imirongo myinshi yumuriro mwinshi hamwe n’ibikoresho bikoresha ingufu nyinshi, ibikoresho bya SiC byakoreshejwe cyane mu bucuruzi. Iterambere ryihuta. Nyuma yimyaka hafi 10 yiterambere, inzira yibikoresho bya SiC yashoboye gukora ibikoresho byubucuruzi. Ibigo byinshi bihagarariwe na Cree byatangiye gutanga ibicuruzwa byubucuruzi bwibikoresho bya SiC. Ibigo byubushakashatsi bwimbere mu gihugu na kaminuza nabyo byageze ku ntera ishimishije mu kuzamura ibikoresho bya SiC hamwe n’ikoranabuhanga rikora ibikoresho. Nubwo ibikoresho bya SiC bifite imiterere isumba iyindi yumubiri nubumashini, kandi tekinoroji ya ibikoresho bya SiC nayo irakuze, ariko imikorere yibikoresho bya SiC hamwe nizunguruka ntabwo biri hejuru. Usibye ibikoresho bya SiC nibikoresho bigomba guhora bitezimbere. Hagomba gushyirwaho ingufu nyinshi muburyo bwo gukoresha ibikoresho bya SiC mugutezimbere ibikoresho bya S5C cyangwa gusaba ibikoresho bishya.
Kugeza ubu. Ubushakashatsi bwibikoresho bya SiC byibanda cyane kubikoresho byihariye. Kuri buri bwoko bwibikoresho byubushakashatsi, ubushakashatsi bwambere nuguhindura gusa imiterere yibikoresho bya Si cyangwa GaAs bihuye na SiC utabanje guhindura imiterere yibikoresho. Kubera ko imbere ya oxyde ya SiC isa na Si, ari yo SiO2, bivuze ko ibikoresho byinshi bya Si, cyane cyane ibikoresho bya m-pa, bishobora gukorerwa kuri SiC. Nubwo ari transplant yoroheje gusa, bimwe mubikoresho byabonetse byageze ku bisubizo bishimishije, kandi bimwe mubikoresho byinjiye ku isoko ryuruganda.
Ibikoresho bya SiC optoelectronic, cyane cyane urumuri rwubururu rutanga diode (BLU-ray leds), byinjiye ku isoko mu ntangiriro ya za 90 kandi ni byo bikoresho bya mbere byakozwe na SiC. Umuvuduko mwinshi wa SiC Schottky diode, SiC RF transistors, SiC MOSFETs na mesFETs nazo ziraboneka mubucuruzi. Birumvikana ko imikorere yibi bicuruzwa byose bya SiC iri kure yo gukina ibintu biranga ibikoresho bya SiC, kandi imikorere ikomeye nigikorwa cyibikoresho bya SiC biracyakenewe ubushakashatsi no gutezwa imbere. Ihindurwa ryoroshye akenshi ntirishobora gukoresha neza ibyiza byibikoresho bya SiC. Ndetse no mubice bimwe byiza byibikoresho bya SiC. Bimwe mubikoresho bya SiC byabanje gukorwa ntibishobora guhuza imikorere yibikoresho bihuye na Si cyangwa CaAs.
Kugirango duhindure neza ibyiza biranga ibikoresho bya SiC mubyiza byibikoresho bya SiC, kuri ubu turimo kwiga uburyo bwo kunoza uburyo bwo gukora ibikoresho nuburyo bwimikorere cyangwa guteza imbere imiterere mishya nuburyo bushya bwo kunoza imikorere nimikorere yibikoresho bya SiC.
