Silicon Carbide Manufacturing Kev lag luam
Piv nrogsilicon-raws liCov khoom siv hluav taws xob semiconductor, cov khoom siv hluav taws xob thib peb uas sawv cev los ntawm silicon carbide (SiC) muaj ntau yam zoo xws li hluav taws xob tawg siab, siab saturated electron drift ceev, thiab thermal conductivity.
Silicon carbide fais fab khoom siv tsuas yog siv nyob rau hauv high-power fields, xws li lub zog tshiab tsheb, photovoltaic zog cia, rail transit thiab lwm yam teb, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm tsheb. Hauv ob peb xyoos tom ntej no, cov ntawv thov xws li on-board main inverters thiab charging modules yuav txuas ntxiv mus rau qhov kev kub ceev.
Tam sim no, cov tuam txhab lag luam hauv tsev tau nrawm lawv nkag mus rau hauv silicon carbide kev lag luam saw, thiab kev siv peev nyiaj tau nrawm dua, coj kev loj hlob sai ntawm txhua qhov txuas ntawm kev lag luam saw.
Raws li Yole tsab ntawv ceeb toom, kev lag luam loj ntawm silicon carbide cov khoom siv hluav taws xob yuav ntau dua $ 6 nphom hauv xyoo 2027, nrog rau kev loj hlob txhua xyoo ntawm ntau dua 30%.
Lub zog ntawm silicon carbidentaus ntawv kev lag luam saw feem ntau suav nrog upstream silicon carbide substrate npaj, epitaxial txheej loj hlob, midstream ntaus ntawv raug thiab downstream daim ntawv thov kev lag luam.
Cov txheej txheem kev npaj substrate yog tsuas yog los tsim cov pa roj carbon monoxide high-purity silicon hmoov rau hauv silicon carbide hmoov. Nyob rau hauv qhov tshwj xeeb qhov kub thiab txias, lub cev vapor hloov txoj kev (PVT txoj kev) yog siv los loj hlob silicon carbide siv lead ua ingot ntawm ntau qhov sib txawv, thiab silicon carbide substrate yog tsim tom qab ntau yam txheej txheem.
Qhov sib txuas ntawm epitaxial feem ntau yog nyob rau ntawm silicon carbide substrate, thiab daim ntawv epitaxial yog tsim rau ntawm lub substrate nto los ntawm chemical vapor deposition (CVD) txoj kev.
Ntawm lawv, silicon carbide epitaxial daim ntawv yog npaj los ntawm kev loj hlob silicon carbide epitaxial txheej ntawm conductive silicon carbide substrate, uas tuaj yeem ua ntxiv rau hauv cov khoom siv fais fab thiab siv rau hauv tsheb tshiab, photovoltaic, rail transit, smart grid, aerospace thiab lwm yam kev lag luam. Silicon raws li gallium nitride (GaN-on-SiC) epitaxial daim ntawv yog npaj los ntawm kev loj hlob gallium nitride epitaxial txheej ntawm semi-insulated silicon carbide substrate, uas tuaj yeem npaj ntxiv rau hauv microwave RF thiab siv hauv 5G kev sib txuas lus.
Los ntawm cov nqi tsim khoom ntawm cov khoom siv silicon carbide, tus nqi substrate yog qhov loj tshaj plaws, suav txog 47%; Qhov thib ob yog tus nqi txuas ntxiv, suav txog 23%. Ob txheej txheem no yog cov khoom tseem ceeb ntawm SiC li.
