Kwiminyaka yakutshanje, ngokungena ngokuqhubekayo kwezicelo ezisezantsi ezifana nezithuthi zamandla amatsha, ukuveliswa kwamandla e-photovoltaic, kunye nokugcinwa kwamandla, i-SiC, njengento entsha ye-semiconductor, idlala indima ebalulekileyo kule mimandla.Ngokutsho kweNgxelo yeMarike ye-Yole Intelligence's Power SiC ekhutshwe ngo-2023, kuqikelelwa ukuba ngo-2028, ubungakanani bemarike yehlabathi jikelele yamandla e-SiC izixhobo ziya kufikelela malunga ne-9 yeebhiliyoni zeedola, ezimele ukukhula okumalunga ne-31% xa kuthelekiswa no-2022. i-semiconductors ibonisa ulwando oluqhubekayo.
Phakathi kwezicelo ezininzi zentengiso, iimoto zamandla amatsha zilawula ngesabelo semarike esingama-70%.Okwangoku, i-China iye yaba ngumvelisi omkhulu wehlabathi, umthengi, kunye nomthengisi wezithuthi ezintsha zamandla.Ngokuka- "Nikkei Asian Review," ngo-2023, eqhutywa zizithuthi zamandla amatsha, ukuthunyelwa kweemoto zase-China kwadlula iJapan okokuqala, nto leyo eyenza i-China ibe lelona lizwe lithumela iimoto kumazwe angaphandle.
Ijongene nemfuno ekhulayo yemarike, ishishini laseTshayina leSiC lingenisa ithuba elibalulekileyo lophuhliso.
Ukususela ekukhululweni kwe "Isicwangciso seminyaka yeshumi elinesithathu" kwiSayensi yeSizwe kunye neTekhnoloji yokuQala ngokutsha yiBhunga likaRhulumente ngoJulayi 2016, ukuphuhliswa kwee-chips ze-semiconductor zesizukulwana sesithathu kuye kwafumana ingqalelo ephezulu kurhulumente kwaye ifumene iimpendulo ezintle kunye nenkxaso ebanzi imimandla eyahlukeneyo.Ngo-Agasti ka-2021, uMphathiswa wezoShishino kunye nobuChwepheshe boLwazi (i-MIIT) iphinde yaquka ii-semiconductors zesizukulwana sesithathu "kwiSicwangciso seMinyaka yeshumi elineSine" yophuhliso lwesayensi yemizi-mveliso kunye nophuhliso lobugcisa, nto leyo efaka umfutho ongakumbi kuhlumo lwemalike yeSiC yasekhaya.
Iqhutywa zizo zombini ezi mfuno zentengiso kunye nemigaqo-nkqubo, iiprojekthi zeshishini le-SiC zasekhaya zivela ngokukhawuleza njengamakhowa emva kwemvula, zibonakalisa imeko yophuhliso olunabileyo.Ngokweenkcukacha-manani zethu ezingagqitywanga, ukuza kuthi ga ngoku, iiprojekthi zokwakha ezinxulumene ne-SiC ziye zabekwa ubuncinane kwizixeko ezili-17.Phakathi kwazo, iJiangsu, iShanghai, iShandong, iZhejiang, iGuangdong, iHunan, iFujian, kunye neminye imimandla iye yaba ziindawo ezibalulekileyo zophuhliso loshishino lweSiC.Ngokukodwa, ngeprojekthi entsha ye-ReTopTech efakwe kwimveliso, iya komeleza ngakumbi ikhonkco lemveliso ye-semiconductor yesizukulwana sesithathu, ngakumbi eGuangdong.
Uyilo olulandelayo lwe-ReTopTech yi-8-intshi ye-SiC substrate.Nangona ii-intshi ezi-6 ze-SiC substrates zilawula ngoku kwimarike, indlela yophuhliso loshishino ngokuthe ngcembe itshintshela kwii-intshi ezisi-8 ngenxa yokuqwalaselwa kweendleko.Ngokwengqikelelo ye-GTAT, ixabiso le-8-intshi ye-substrates kulindeleke ukuba licuthwe nge-20% ukuya kwi-35% xa kuthelekiswa ne-6-intshi engaphantsi.Okwangoku, abavelisi be-SiC abaziwayo abafana neWolfspeed, i-ST, i-Coherent, i-Soitec, i-Sanan, i-Taike Tianrun, kunye ne-Xilinx Integration, yasekhaya nakwamanye amazwe, sele iqalile ukutshintshela ngokuthe ngcembe kwii-substrates ze-8-intshi.
Kulo mongo, i-ReTopTech iceba ukuseka i-Large-Size Crystal Growth kunye ne-Epitaxy Technology Research and Development Centre kwixesha elizayo.Inkampani iya kusebenzisana kunye neebhubhoratri eziphambili zendawo ukubandakanya intsebenziswano kwisixhobo kunye nokwabelana ngezixhobo kunye nophando lwezinto eziphathekayo.Ukongeza, i-ReTopTech iceba ukuqinisa intsebenziswano entsha kwitekhnoloji yokucubungula ikristale kunye nabavelisi abakhulu bezixhobo kunye nokubandakanyeka kwinguqulelo edibeneyo kunye namashishini ahamba phambili asezantsi kuphando kunye nophuhliso lwezixhobo zeemoto kunye neemodyuli.La manyathelo ajolise ekonyuseni umgangatho wophando nophuhliso kunye noshishino lwase-China lokwenziwa kwethekhnoloji kummandla wamaqonga ee-intshi ezisi-8.
I-semiconductor yesizukulwana sesithathu, kunye ne-SiC njengommeli wayo ophambili, yamkelwa jikelele njengenye yezona ndawo zithembisayo ngaphakathi kwishishini le-semiconductor lilonke.I-China inelungelo elipheleleyo lomxokelelwane wemizi-mveliso kwisizukulwana sesithathu semiconductors, izixhobo ezigqumayo, imathiriyeli, imveliso, kunye nokusetyenziswa, okunamandla okuseka ukhuphiswano lwehlabathi.
