Sharaxaad Gaaban:

Silicon carbide (SiC) waa isku-dhis laba-geesood ah oo ka tirsan Kooxda IV-IV, waa isku-dhis adag oo kaliya oo deggan Kooxda IV ee Shaxda Curiyeyaasha ee Xilliyeedka, Waa semiconductor muhiim ah. SiC waxay leedahay sifooyin kuleyl, farsamo, kiimiko iyo koronto oo aad u fiican, taas oo ka dhigaysa mid ka mid ah agabka ugu wanaagsan ee lagu sameeyo aaladaha elektaroonigga ah ee heerkulka sare, soo noqnoqoshada sare, iyo kuwa awoodda sare leh.

Isticmaalka substrate silicon carbide

Substrate-ka carbide-ka ee silikoon waxaa loo qaybin karaa nooca gudbiyaha iyo nooca nus-daboolida iyadoo loo eegayo iska caabinta. Qalabka carbide-ka ee silikoon-ka ee gudbiya waxaa inta badan loo isticmaalaa gawaarida korontada, korontada dhaliya, gaadiidka tareenka, xarumaha xogta, dallacaadda iyo kaabayaasha kale. Warshadaha baabuurta korontada ku shaqeeya waxay leeyihiin baahi weyn oo loo qabo substrate-ka carbide-ka ee gudbiya, haddana, Tesla, BYD, NIO, Xiaopeng iyo shirkadaha kale ee cusub ee baabuurta tamarta ayaa qorsheeyay inay isticmaalaan aaladaha ama modules-ka kala duwan ee carbide-ka silikoon.

Aaladaha carbide-ka silicon ee nus-insulated waxaa inta badan loo isticmaalaa isgaarsiinta 5G, isgaarsiinta gawaarida, codsiyada difaaca qaranka, gudbinta xogta, hawada sare iyo meelo kale. Iyadoo la kordhinayo lakabka epitaxial-ka gallium nitride ee ku yaal substrate-ka carbide-ka silicon ee nus-insulated, wafer-ka epitaxial-ka gallium nitride ee ku salaysan silicon waxaa loo sii samayn karaa aaladaha microwave RF, kuwaas oo inta badan loo isticmaalo goobta RF, sida qalabka kor u qaada korontada ee isgaarsiinta 5G iyo qalabka raadiyaha ee difaaca qaranka.

Soo saarista wax soo saarka walxaha silicon carbide waxaa ka mid ah horumarinta qalabka, isku-darka walxaha ceeriin ah, koritaanka kiristaalka, jarista kiristaalka, farsamaynta wafer, nadiifinta iyo tijaabinta, iyo xiriiro kale oo badan. Marka la eego walxaha ceeriin ah, warshadaha Songshan Boron waxay siiyaan suuqa agabka ceeriin ee silicon carbide, waxayna gaareen iib yar. Agabka semiconductor-ka jiilka saddexaad ee uu matalo silicon carbide ayaa door muhiim ah ka ciyaara warshadaha casriga ah, iyadoo la dardar gelinayo gelitaanka gawaarida tamarta cusub iyo codsiyada sawir-qaadista, baahida loo qabo substrate-ka silicon carbide ayaa ku dhow inay keento bar isbeddel.
