Qalabka Semiconductor-ka waa xudunta qalabka casriga ah ee warshadaha, oo si weyn loogu isticmaalo kombiyuutarrada, qalabka elektaroonigga macaamiisha, isgaarsiinta shabakadda, qalabka elektaroonigga baabuurta, iyo meelaha kale ee xudunta, warshadaha semiconductor-ka waxay inta badan ka kooban yihiin afar qaybood oo aasaasi ah: wareegyada isku dhafan, aaladaha optoelectronic, qalabka kala go'a, dareemaha, kaas oo ka badan 80% wareegyada isku dhafan, badanaa iyo wareegyada semiconductor-ka iyo wareegyada isku dhafan.
Wareegga isku dhafan, sida ku cad qaybta wax soo saarka, waxaa inta badan loo qaybiyaa afar qaybood: microprocessor, xusuusta, aaladaha macquulka ah, qaybaha simulator-ka. Si kastaba ha ahaatee, iyadoo la ballaarinayo si joogto ah goobta codsiga ee aaladaha semiconductor-ka, munaasabado badan oo gaar ah waxay u baahan yihiin semiconductor-yada inay awoodaan inay u hoggaansamaan isticmaalka heerkulka sare, shucaaca xooggan, awoodda sare iyo deegaanno kale, ma dhaawacmaan, jiilka koowaad iyo kan labaad ee walxaha semiconductor-ka waa kuwo aan awood lahayn, sidaa darteed jiilka saddexaad ee walxaha semiconductor-ka ayaa soo galay.
Waqtigan xaadirka ah, walxaha semiconductor-ka ee farqiga ballaaran waxaa matalayasilikoon carbide(SiC), gallium nitride (GaN), zinc oxide (ZnO), dheeman, aluminium nitride (AlN) ayaa suuqa ugu badan ku leh faa'iidooyin badan, oo si wadajir ah loogu yeero walxaha semiconductor-ka jiilka saddexaad. Jiilka saddexaad ee walxaha semiconductor-ka oo leh ballaca farqiga band ballaaran, ayaa sare u kaca goobta korantada ee burburka, gudbinta kulaylka, heerka buuxa ee elektaroonigga ah iyo awoodda sare ee iska caabbinta shucaaca, oo ku habboon sameynta heerkul sare, soo noqnoqoshada sare, iska caabbinta shucaaca iyo aaladaha awoodda sare leh, oo badanaa loo yaqaan walxaha semiconductor-ka bandgap ballaaran (ballaca band ee la mamnuucay waa ka weyn yahay 2.2 eV), oo sidoo kale loo yaqaan heerkulka sare ee walxaha semiconductor-ka. Laga soo bilaabo cilmi-baarista hadda socota ee ku saabsan agabka semiconductor-ka jiilka saddexaad iyo aaladaha, agabka semiconductor-ka silicon carbide iyo gallium nitride gallium nitride waa kuwo aad u bisil, iyotiknoolajiyada carbide-ka siliconwaa kan ugu bisil, halka cilmi-baarista ku saabsan zinc oxide, dheeman, aluminium nitride iyo agabyo kale ay weli ku jirto marxaladdii ugu horreysay.
Agabka iyo Hantidooda:
Kaarboohaydraytka silikoonka ahagabka waxaa si weyn loogu isticmaalaa meelaha lagu ciyaaro kubbadda dhoobada, waalka, qalabka semiconductor-ka, gyros-ka, qalabka cabbirka, hawada sare iyo meelaha kale, wuxuu noqday walxo aan la beddeli karin oo ku yaal goobo badan oo warshadeed.
SiC waa nooc ka mid ah superlattice dabiici ah iyo polytype caadi ah oo isku mid ah. Waxaa jira in ka badan 200 oo qoys oo polytypic ah (hadda la yaqaan) oo isku mid ah sababtoo ah farqiga u dhexeeya taxanaha baakadaha ee u dhexeeya lakabka diatomic-ka Si iyo C, taasoo horseedaysa qaab-dhismeedyo kala duwan oo kiristaal ah. Sidaa darteed, SiC aad ayuu ugu habboon yahay jiilka cusub ee walxaha substrate-ka ee diode-ka iftiinka soo saaraya (LED), agabyada elektaroonigga ah ee awoodda sare leh.

| hantida jireed | Adkaanta sare (3000kg/mm), waxay jari kartaa ruby |
| Iska caabin sare oo xirasho, oo ka dambeysa dheemanka oo keliya | |
| Qaboojinta kulaylka ayaa 3 jeer ka sarreysa tan Si iyo 8 ~ 10 jeer ka sarreysa tan GaAs. | |
| Xasilloonida kulaylka ee SiC waa mid sareysa mana suurtowdo in lagu dhalaalo cadaadiska jawiga | |
| Waxqabadka wanaagsan ee kala-baxa kulaylka ayaa aad muhiim ugu ah aaladaha awoodda sare leh | |

hantida kiimikada | Iska caabin aad u xooggan oo daxalka ah, oo u adkaysta ku dhawaad walax kasta oo la yaqaan oo ku jirta heerkulka qolka |
| Dusha sare ee SiC si fudud ayay u oksaydhaysaa si ay u samayso SiO2, lakab khafiif ah, waxay ka hortagi kartaa oksaydheyn dheeraad ah, Ka sarreeya 1700 ℃, filimka oksaydhka ayaa dhalaala oo si dhakhso ah ayuu u oksaydhaa | |
| Farqiga u dhexeeya 4H-SIC iyo 6H-SIC waa qiyaastii 3 jeer ka badan kan Si iyo 2 jeer ka badan kan GaAs: Xoogga goobta korantada ee burburka waa amar baaxad leh oo ka sarreeya Si, xawaaraha qulqulka elektaroonigana waa mid buuxa Laba iyo badh jeer ayay Si. Ballaca bandgap ee 4H-SIC wuu ka ballaaran yahay kan 6H-SIC. |
