M'zaka zaposachedwa, ndi kulowa kosalekeza kwa ntchito zotsika pansi monga magalimoto amagetsi atsopano, magetsi a photovoltaic, ndi kusungirako mphamvu, SiC, monga chinthu chatsopano cha semiconductor, imagwira ntchito yofunika kwambiri m'madera awa.Malinga ndi Yole Intelligence's Power SiC Market Report yomwe idatulutsidwa mu 2023, zikunenedweratu kuti pofika 2028, kukula kwa msika wamagetsi padziko lonse lapansi wa zida za SiC kudzafika pafupifupi $9 biliyoni, zomwe zikuyimira kukula kwa pafupifupi 31% poyerekeza ndi 2022. Kukula kwa msika wonse wa SiC ma semiconductors akuwonetsa kufalikira kokhazikika.
Pakati pa ntchito zambiri zamsika, magalimoto amagetsi atsopano amalamulira ndi gawo la msika la 70%.Pakadali pano, China yakhala dziko lalikulu kwambiri padziko lonse lapansi kupanga, ogula, ndi kutumiza kunja kwa magalimoto amagetsi atsopano.Malinga ndi "Nikkei Asian Review," mu 2023, motsogozedwa ndi magalimoto amagetsi atsopano, magalimoto aku China adadutsa Japan koyamba, zomwe zidapangitsa China kukhala wogulitsa magalimoto ambiri padziko lonse lapansi.
Poyang'anizana ndi kufunikira kwa msika komwe kukukulirakulira, makampani aku China a SiC akubweretsa mwayi wofunikira wachitukuko.
Chiyambireni kutulutsidwa kwa "Mapulani a Zaka khumi ndi Zisanu" za National Science and Technology Innovation ndi State Council mu July 2016, chitukuko cha tchipisi ta m'badwo wachitatu chalandira chidwi chachikulu kuchokera ku boma ndipo chalandira mayankho abwino ndi thandizo lalikulu mu madera osiyanasiyana.Pofika mu Ogasiti 2021, Unduna wa Zamakampani ndi Ukadaulo Wachidziwitso (MIIT) udaphatikizanso ma semiconductors am'badwo wachitatu mu "Mapulani a Zaka khumi ndi zinayi" pakukula kwaukadaulo wamafakitale ndiukadaulo, zomwe zikukulitsa kukula kwa msika wapakhomo wa SiC.
Motsogozedwa ndi kufunikira kwa msika ndi ndondomeko, mapulojekiti akunyumba a SiC akutuluka mwachangu ngati bowa pambuyo pa mvula, zomwe zikuwonetsa chitukuko chofala.Malinga ndi ziwerengero zathu zosakwanira, kuyambira pano, ntchito zomanga zokhudzana ndi SiC zatumizidwa m'mizinda osachepera 17.Pakati pawo, Jiangsu, Shanghai, Shandong, Zhejiang, Guangdong, Hunan, Fujian, ndi zigawo zina zakhala malo ofunikira pakukula kwamakampani a SiC.Makamaka, ndi pulojekiti yatsopano ya ReTopTech yomwe yakhazikitsidwa, ilimbikitsanso makampani onse apakhomo a m'badwo wachitatu, makamaka ku Guangdong.
Kapangidwe kotsatira ka ReTopTech ndi gawo la 8-inch SiC.Ngakhale magawo a 6-inchi a SiC akulamulira msika pano, chitukuko chamakampani chikusintha pang'onopang'ono kupita ku magawo 8-inchi chifukwa chakuchepetsa mtengo.Malinga ndi kuneneratu kwa GTAT, mtengo wa magawo 8-inch ukuyembekezeka kuchepetsedwa ndi 20% mpaka 35% poyerekeza ndi magawo 6-inch.Pakalipano, opanga SiC odziwika bwino monga Wolfspeed, ST, Coherent, Soitec, Sanan, Taike Tianrun, ndi Xilinx Integration, onse apakhomo ndi akunja, ayamba kusintha pang'onopang'ono ku magawo a 8-inch.
M'nkhaniyi, ReTopTech ikukonzekera kukhazikitsa Crystal kukula kwakukulu ndi Epitaxy Technology Research and Development Center m'tsogolomu.Kampaniyo ithandizana ndi ma laboratories am'deralo kuti achite nawo mgwirizano pakugawana zida ndi zida komanso kufufuza zinthu.Kuphatikiza apo, ReTopTech ikukonzekera kulimbikitsa mgwirizano waukadaulo muukadaulo wopanga ma kristalo ndi opanga zida zazikulu ndikuchita nawo zatsopano zamabizinesi otsogola pakufufuza ndi kupanga zida zamagalimoto ndi ma module.Njirazi zikufuna kupititsa patsogolo luso laukadaulo la China pakufufuza ndi chitukuko ndi chitukuko cha mafakitale pantchito zamapulatifomu apakati a 8-inch.
Semiconductor ya m'badwo wachitatu, ndi SiC monga woyimilira wamkulu, amadziwika padziko lonse lapansi ngati imodzi mwamagawo odalirika kwambiri pamsika wonse wa semiconductor.China ili ndi mwayi wathunthu wamafakitale pama semiconductors am'badwo wachitatu, zida zophimba, zida, kupanga, ndi kugwiritsa ntchito, zomwe zimatha kukhazikitsa mpikisano wapadziko lonse lapansi.
