Lilemong tsa morao tjena, ka ho kenella ho tsoelang pele ha lits'ebetso tse tlaase tse kang likoloi tse ncha tsa matla, motlakase oa photovoltaic, le polokelo ea matla, SiC, e le thepa e ncha ea semiconductor, e phetha karolo ea bohlokoa masimong ana. Ho latela Yole Intelligence's Power SiC Market Report e lokollotsoeng ka 2023, ho boletsoe esale pele hore ka 2028, boholo ba mmaraka oa lefats'e oa lisebelisoa tsa SiC bo tla fihla hoo e ka bang $ 9 billion, e emelang kholo ea hoo e ka bang 31% ha e bapisoa le 2022. Kakaretso ea boholo ba mmaraka ea SiC. li-semiconductors li bonts'a mokhoa o tsitsitseng oa katoloso.
Har'a lits'ebetso tse ngata tsa 'maraka, likoloi tse ncha tsa motlakase li busa ka karolo ea 70% ea mmaraka. Hajoale, China e fetohile mohlahisi e moholo ka ho fetisisa lefatšeng, moreki le morekisi oa likoloi tse ncha tsa motlakase. Ho ea ka "Nikkei Asian Review," ka 2023, e tsamaisoang ke likoloi tse ncha tsa matla, thepa ea likoloi tsa Chaena e ile ea feta Japane ka lekhetlo la pele, e leng se ileng sa etsa hore China e be morekisi e moholo ka ho fetisisa lefatšeng oa likoloi.
Ha e tobane le tlhokeho e ntseng e eketseha ea 'maraka, indasteri ea SiC ea China e tlisa monyetla oa bohlokoa oa nts'etsopele.
Ho tloha ha ho lokolloa "Leano la Lilemo tse Leshome le Metso e Mehlano" bakeng sa Tlhahiso ea Naha ea Saense le Theknoloji ke Lekhotla la Naha ka Phupu 2016, nts'etsopele ea li-semiconductor chips ea moloko oa boraro e fumane tlhokomelo e kholo ho tsoa mmusong mme e fumane likarabo tse ntle le tšehetso e pharaletseng ho libaka tse fapaneng. Ka Phato 2021, Lekala la Indasteri le Theknoloji ea Tlhahisoleseding (MIIT) le kenyellelitse li-semiconductors tsa moloko oa boraro ho "Leano la Lilemo tse Mehlano" bakeng sa nts'etsopele ea mahlale a mahlale le mahlale a mahlale a indasteri, e kenyang matla a eketsehileng kholong ea 'maraka oa lehae oa SiC.
E susumetsoa ke tlhokahalo ea 'maraka le maano, merero ea indasteri ea SiC ea malapeng e hlaha ka potlako joaloka li-mushroom ka mor'a pula, e hlahisa boemo ba tsoelo-pele e atileng. Ho latela lipalo-palo tsa rona tse sa phethahalang, ho tloha hajoale, merero ea kaho e amanang le SiC e se e kentsoe bonyane litoropong tse 17. Har'a tsona, Jiangsu, Shanghai, Shandong, Zhejiang, Guangdong, Hunan, Fujian, le libaka tse ling li fetohile libaka tsa bohlokoa bakeng sa nts'etsopele ea indasteri ea SiC. Haholo-holo, ka projeke e ncha ea ReTopTech e kentsoeng tlhahisong, e tla tsoela pele ho matlafatsa ketane ea indasteri ea semiconductor ea moloko oa boraro, haholo Guangdong.
Sebopeho se latelang sa ReTopTech ke 8-inch SiC substrate. Leha li-substrates tsa 6-inch SiC li ntse li laola 'maraka, mokhoa oa nts'etsopele ea indasteri o ntse o fetohela ho li-substrates tsa 8-inch ka lebaka la menahano ea phokotso ea litšenyehelo. Ho latela likhakanyo tsa GTAT, theko ea li-substrates tse 8-inch e lebelletsoe ho fokotseha ka 20% ho isa ho 35% ha e bapisoa le 6-inch substrates. Hona joale, baetsi ba SiC ba tsebahalang ba kang Wolfspeed, ST, Coherent, Soitec, Sanan, Taike Tianrun, le Xilinx Integration, ba malapeng le ba machaba, ba qalile ho fetela butle-butle ho li-substrates tsa 8-inch.
Boemong bona, ReTopTech e rera ho theha Setsi sa Khōlo ea Crystal ea Boholo bo Boholo le Epitaxy Technology Research and Development Center nakong e tlang. Khampani e tla sebelisana le lilaboratori tsa bohlokoa tsa lehae ho kenya letsoho tšebelisanong ka ho arolelana lisebelisoa le lisebelisoa le lipatlisiso tsa thepa. Ho feta moo, ReTopTech e rera ho matlafatsa tšebelisano-'moho ho theknoloji ea ho lokisa kristale le bahlahisi ba ka sehloohong ba lisebelisoa le ho kenya letsoho boiqapelong bo kopaneng le likhoebo tse etellang pele ho etsa lipatlisiso le nts'etsopele ea lisebelisoa tsa likoloi le li-module. Mehato ena e ikemiselitse ho ntlafatsa boemo ba China ba lipatlisiso le nts'etsopele le tlhahiso ea thekenoloji ea indasteri lefapheng la li-platform tsa 8-inch substrate.
Semiconductor ea moloko oa boraro, 'me SiC e le moemeli oa eona ea ka sehloohong, e tsejoa hohle e le e' ngoe ea libaka tse tšepisang ka ho fetisisa ka har'a indasteri eohle ea semiconductor. China e na le monyetla o felletseng oa ketane ea indasteri ho li-semiconductors tsa moloko oa boraro, lisebelisoa tse koahelang, lisebelisoa, tlhahiso le lits'ebetso, ka monyetla oa ho theha tlholisano ea lefats'e.
