Cov yam ntxwv tseem ceeb ntawm Silicon Carbide
Dav Bandgap Semiconductor Cov Khoom Muaj
Siab thermal conductivity (3 × silicon)
Kev kub hnyav thiab kev tiv thaiv kev pheej hmoo
Tshaj Plaws Hloov Khoom
Kev siv hluav taws xob zoo heev
Kev Lag Luam Txheej Txheem & Kev Loj Hlob Tsav
Lub ntiaj teb silicon silicon carbide (sic) kev ua lag luam tau nthuav tawm sai sai, uas tau tsav los ntawm kev nce ntxiv rau lub zog hluav taws xob thoob plaws ntau yam kev lag luam. Raws li cov ntaub ntawv kev lag luam (piv txwv li, yole dévelpement, mckinsey), kev ua lag luam sic tau npaj siab nyob rau ntawm ib lub lim tiam 30-35% los ntawm 2025, muaj ntau tshaj $ 10 nphom los ntawm 2030.
Qhov Muaj Peev Xwm Kev Loj Hlob Ntawm Silicon Carbide
Kev Siv Hluav Taws Xob ntawm Automotive:
SIC-based fais fab cuab yeej (inverers, obcs) txhim kho ev kev ua haujlwm los ntawm 5-10%, txuas ntxiv ntau thiab txo lub sijhawm them rov qab.
Txais los ntawm cov lag luam loj (Tesla, byd, lucid) thiab tier {{{} Tus neeg muag khoom (Bosch, infone) accelerates ua lag luam nkag mus.
Txuas ntxiv zog nthuav dav:
Hnub ci Inverers thiab cua tshuab hloov hloov los ntawm Sic lub General High-voltage tuav thiab qis poob, txhawb kev ua haujlwm.
5G & RF daim ntaub ntawv:
Sic substtrates pab kom high-zog, high-zaus cov cuab yeej siv rau 5G puag ncig thiab satellite sib txuas lus.
Muaj & Aerospace xav tau:
Harsh-Ib puag ncig cov ntawv thov (chaw muaj suab lag luam, kev lag luam, tiv thaiv) leverage sic thermal thiab tshuaj lom neeg ruaj khov.
Kev Sib Tw Toj roob hauv pes & muab khoom
Cov Ntaus:
Substrate Chaw Muag Khoom: Wolfspeed (Asmeskas), II-VI (US), SK Siltoos (Kauslim)
Cov Khoom Siv Ntaus: Stmicoeltronics (Europe), Lub Tebchaws Yelemees), rau ntawm Semiconductor (US), ROHM (JOHM)
Suav Ecosystem:
Cov neeg ua si hauv tsev (SCC, TANKELULE) yog ntsuas 6- nti wafer ntau lawm, txo kev cia siab rau kev sib raug zoo ntawm kev sib raug zoo ntawm kev siv khoom.
Muab cov saw muab cov nyom:
Wafer tsis xws luag & Cov Teeb Meem Teeb Meem:
Micropipes thiab dislocations hauv SIC muaju nce ntau lawm nqi (~ 3-5 × siab dua li Silicon Wafers).
Txwv 8- nti wafer saws saws:
Feem ntau cov ntaub tseem siv 6- nti wafers ,, txawm tias hma thiab II-vi {le} nti ntau lawm rau tus nqi qis.
