Mu myaka yashize, hamwe nogukomeza kwinjirira mubikorwa byo hasi nkibinyabiziga bishya byingufu, kubyara amashanyarazi, no kubika ingufu, SiC, nkibikoresho bishya bya semiconductor, bigira uruhare runini murimurima.Raporo y’isoko rya Power SiC Yole Intelligence yashyizwe ahagaragara mu 2023, biteganijwe ko mu 2028, ingano y’isoko ry’ibikoresho by’amashanyarazi SiC izagera kuri miliyari 9 z'amadolari, bivuze ko izamuka rya hafi 31% ugereranije na 2022. Muri rusange isoko rya SiC semiconductor irerekana uburyo bwagutse bwo kwaguka.
Mubikorwa byinshi byamasoko, ibinyabiziga bishya byiganjemo imigabane 70%.Kugeza ubu, Ubushinwa bwabaye ibihugu byinshi ku isi bitanga umusaruro, bikoresha, kandi byohereza mu mahanga ibinyabiziga bishya by’ingufu.Nk’uko ikinyamakuru "Nikkei Asian Review" kibitangaza, mu 2023, gitwarwa n’imodoka nshya z’ingufu, ibyoherezwa mu modoka by’Ubushinwa byarenze Ubuyapani ku nshuro ya mbere, bituma Ubushinwa buza kohereza ibicuruzwa mu mahanga ku isi.
Mu guhangana n’isoko rikomeje kwiyongera, inganda za SiC mu Bushinwa zitangiza amahirwe akomeye y’iterambere.
Kuva muri Nyakanga 2016 hashyirwaho "Gahunda y’imyaka cumi n'itanu y’imyaka itanu" yo guhanga udushya mu bumenyi n’ikoranabuhanga mu rwego rw’igihugu, muri Nyakanga 2016, iterambere rya chipi ya semiconductor yo mu gisekuru cya gatatu ryitabiriwe cyane na guverinoma kandi ryakira ibisubizo byiza ndetse n’inkunga nini muri uturere dutandukanye.Muri Kanama 2021, Minisiteri y’inganda n’ikoranabuhanga mu itumanaho (MIIT) yongeye gushyiramo igice cya gatatu cy’amashanyarazi muri gahunda ya "Gahunda y’imyaka cumi nine n'itanu" yo guteza imbere ubumenyi bw’inganda n’ikoranabuhanga mu guteza imbere udushya, bituma hashyirwaho ingufu mu kuzamura isoko ry’imbere mu gihugu rya SiC.
Bitewe n’ibisabwa ku isoko na politiki, imishinga y’inganda zo mu gihugu cya SiC ziragenda zigaragara vuba nk ibihumyo nyuma yimvura, bikerekana ibihe byiterambere.Dukurikije imibare yacu ituzuye, kugeza ubu, imishinga y'ubwubatsi ijyanye na SiC yoherejwe mu mijyi nibura 17.Muri bo, Jiangsu, Shanghai, Shandong, Zhejiang, Guangdong, Hunan, Fujian, n'utundi turere byabaye ihuriro rikomeye ry'iterambere ry'inganda za SiC.By'umwihariko, hamwe n'umushinga mushya wa ReTopTech ushyizwe mu musaruro, bizarushaho gushimangira urwego rwose rw’ibisekuru bya gatatu byinjira mu nganda, cyane cyane muri Guangdong.
Imiterere ikurikira kuri ReTopTech ni 8-inimero ya SiC substrate.Nubwo ubu insimburangingo ya 6-SiC yiganje ku isoko, iterambere ryinganda riragenda rihinduka ryerekeza kuri santimetero 8 bitewe no kugabanya ibiciro.Dukurikije ibyo GTAT yahanuye, biteganijwe ko igiciro cya santimetero 8 ziteganijwe kugabanukaho 20% kugeza kuri 35% ugereranije n’ubutaka bwa santimetero 6.Kugeza ubu, uruganda ruzwi cyane rwa SiC nka Wolfspeed, ST, Coherent, Soitec, Sanan, Taike Tianrun, na Xilinx Integration, haba mu gihugu ndetse no mu mahanga, batangiye kugenda buhoro buhoro kuri santimetero 8.
Ni muri urwo rwego, ReTopTech irateganya gushyiraho Ikura rinini rya Crystal Growth hamwe na Epitaxy Technology Research and Development Centre mugihe kizaza.Isosiyete izafatanya na laboratoire z’ibanze kugira ngo zifatanyirize hamwe mu kugabana ibikoresho n’ibikoresho ndetse n’ubushakashatsi bwibikoresho.Byongeye kandi, ReTopTech irateganya gushimangira ubufatanye bushya mu ikoranabuhanga ritunganya kristu hamwe n’abakora ibikoresho bikomeye kandi bakagira uruhare mu guhanga udushya hamwe n’inganda ziyobora hasi mu bushakashatsi no guteza imbere ibikoresho by’imodoka na modul.Izi ngamba zigamije kuzamura ubushakashatsi n’iterambere ry’Ubushinwa n’inganda zikora inganda mu rwego rwa tekinoroji ya santimetero 8.
Igice cya gatatu cya semiconductor, hamwe na SiC nkuyihagarariye wambere, irazwi kwisi yose nkimwe mumasoko yizewe cyane mubikorwa byose bya semiconductor.Ubushinwa bufite inyungu zuzuye zinganda mu gisekuru cya gatatu cyigice cya kabiri, gikubiyemo ibikoresho, ibikoresho, inganda, hamwe n’ibisabwa, bifite ubushobozi bwo gushyiraho irushanwa ku isi.
