Eminyakeni yamuva, ngokungena okuqhubekayo kwezinhlelo zokusebenza ezingezansi ezifana nezimoto zamandla amasha, ukukhiqizwa kwamandla e-photovoltaic, nokugcinwa kwamandla, i-SiC, njengento entsha ye-semiconductor, idlala indima ebalulekile kule mikhakha.Ngokombiko weMakethe ye-Yole Intelligence's Power SiC okhishwe ngo-2023, kubikezelwa ukuthi ngo-2028, usayizi wemakethe yomhlaba wonke wamadivayisi we-SiC uzofinyelela cishe ku-$9 billion, okumelela ukukhula okucishe kube ngama-31% uma kuqhathaniswa no-2022. Usayizi wemakethe jikelele we-SiC ama-semiconductors akhombisa inkambiso eqhubekayo yokukhula.

Phakathi kwezicelo eziningi zemakethe, izimoto zamandla amasha zibusa ngesabelo semakethe esingu-70%.Njengamanje, i-China isibe ngumkhiqizi, umthengi, kanye nomthumeli wezimoto ezintsha ezihamba phambili emhlabeni.Ngokusho kwe-"Nikkei Asian Review," ngo-2023, eqhutshwa izimoto ezintsha zamandla, ukuthunyelwa kwezimoto zaseChina kwedlula iJapan okokuqala ngqa, okwenza i-China ibe ngumhwebi omkhulu wezimoto emhlabeni.

Ibhekene nesidingo esikhulayo semakethe, imboni ye-SiC yaseChina ingenisa ithuba elibalulekile lentuthuko.

Kusukela kwakhululwa "Uhlelo Lweminyaka Eyishumi Nantathu" Lokusungula Kazwelonke KwezeSayensi Nobuchwepheshe nguMkhandlu Wombuso ngoJulayi 2016, ukuthuthukiswa kwama-semiconductor chips esizukulwane sesithathu kuthole ukunakwa okuphezulu kuhulumeni futhi sekuthole izimpendulo ezinhle nokusekelwa okubanzi izifunda ezihlukahlukene.Ngo-Agasti 2021, uMnyango Wezimboni Nobuchwepheshe Bolwazi (MIIT) uphinde wafaka ama-semiconductors esizukulwane sesithathu "Ohlelweni Lweminyaka Eyishumi Nane" lokuthuthukiswa kokusungulwa kwesayensi yezimboni nobuchwepheshe, okufakela umfutho ekukhuleni kwemakethe yasekhaya ye-SiC.

Iqhutshwa yikho kokubili isidingo semakethe nezinqubomgomo, amaphrojekthi emboni ye-SiC yasekhaya avela ngokushesha njengamakhowe ngemva kwemvula, ethula isimo sentuthuko esabalele.Ngokwezibalo zethu ezingaphelele, kusukela manje, amaphrojekthi wokwakha ahlobene ne-SiC atshalwe okungenani emadolobheni angu-17.Phakathi kwazo, iJiangsu, Shanghai, Shandong, Zhejiang, Guangdong, Hunan, Fujian, nezinye izifunda seziphenduke izikhungo ezibalulekile zokuthuthukisa imboni yeSiC.Ikakhulukazi, ngephrojekthi entsha ye-ReTopTech efakwe ekukhiqizweni, izophinde iqinise lonke uchungechunge lwemboni ye-semiconductor yesizukulwane sesithathu, ikakhulukazi e-Guangdong.

Isakhiwo esilandelayo se-ReTopTech yi-8-inch SiC substrate.Nakuba ama-substrates angu-6-intshi e-SiC ebusa emakethe njengamanje, ukuthambekela kokuthuthukiswa komkhakha kancane kancane kushintshela kuma-substrates angu-8-intshi ngenxa yokucatshangelwa kokunciphisa izindleko.Ngokwezibikezelo ze-GTAT, izindleko zama-substrates angu-8-intshi kulindeleke ukuthi zehliswe ngo-20% ziye ku-35% uma kuqhathaniswa nama-substrates angu-6-intshi.Njengamanje, abakhiqizi be-SiC abaziwayo abafana ne-Wolfspeed, i-ST, i-Coherent, i-Soitec, i-Sanan, i-Taike Tianrun, ne-Xilinx Integration, kokubili ekhaya nakwamanye amazwe, sebeqalile ukushintshela kancane kancane kuma-substrates angu-8-intshi.

Kulo mongo, i-ReTopTech ihlela ukusungula i-Large-Size Crystal Growth kanye ne-Epitaxy Technology Research and Development Centre esikhathini esizayo.Inkampani izosebenzisana namalabhorethri abalulekile endawo ukuze ihlanganyele ekwabelaneni ngezinsimbi nezisetshenziswa kanye nocwaningo lwezinto ezibonakalayo.Ukwengeza, i-ReTopTech ihlela ukuqinisa ukusebenzisana okusha kubuchwepheshe bokucubungula ikristalu nabakhiqizi abakhulu bemishini futhi ihlanganyele emisha ehlanganyelwe namabhizinisi ahamba phambili ahamba phambili ocwaningweni nasekuthuthukisweni kwemishini yezimoto namamojula.Lezi zinyathelo zihlose ukuthuthukisa izinga locwaningo nentuthuko yaseShayina kanye nezinga lokukhiqiza izimboni emkhakheni wamapulatifomu angama-intshi angu-8.

I-semiconductor yesizukulwane sesithathu, ene-SiC njengommeleli wayo oyinhloko, yaziwa emhlabeni wonke njengenye yezindawo ezincane ezithembisa kakhulu kuyo yonke imboni ye-semiconductor.I-China inenzuzo ephelele yochungechunge lwezimboni kuma-semiconductors esizukulwane sesithathu, ahlanganisa amathuluzi, izinto zokwakha, ukukhiqiza, kanye nezicelo, okunamandla okusungula ukuncintisana komhlaba.
