Pakazosvika 2023, indasitiri yemotokari ichaverengera makumi manomwe kusvika makumi masere muzana emusika weSiC mudziyo. Sezvo huwandu hunowedzera, zvishandiso zveSiC zvichange zvichinyanya kushandiswa mumaindasitiri ekushandisa senge magetsi emagetsi majaja uye magetsi emagetsi, pamwe negirinhi simba rekushandisa senge photovoltaic uye simba remhepo.
Sekureva kwaYole Intelligence, iyo inofanotaura kugona kwepasi rose kweSiC mudziyo uchapeta katatu panosvika 2027, makambani mashanu epamusoro ndeaya: STMicroelectronics(stmicroelectronics), Infineon Technologies (Infineon), Wolfspeed, onsemi (Anson), uye ROHM (ROM).
Vanotenda kuti musika weSiC mudziyo uchave wakakosha mabhiriyoni matanhatu emadhora mumakore mashanu anotevera uye unogona kusvika madhora bhiriyoni gumi mukutanga kwe2030s.
Inotungamira SiC mutengesi wemidziyo uye wafers muna 2022
8 inch kugadzirwa kwehukuru
Kuburikidza nejira rayo riripo muNew York, USA, Wolfspeed ndiyo yega kambani pasirese inogona kugadzira 8-inch SiC wafers. Hutongi uhu huchaenderera mberi mumakore maviri kusvika matatu anotevera kudzamara mamwe makambani atanga kuvaka hunyanzvi - yekutanga kuve 8-inch SiC chirimwa icho stmicroelectronics ichavhura muItari muna 2024-5.
United States inotungamira nzira muSiC wafers, neWolfspeed ichijoinha Coherent (II-VI), onsemi, uye SK Siltron css, iyo parizvino iri kuwedzera nzvimbo yayo yekugadzira SiC wafer muMichigan. Europe, kune rumwe rutivi, iri kutungamira nzira muSiC zvishandiso.
Saizi yakakura yewaferi inobatsira yakajeka, sezvo nzvimbo yakakura yepamusoro inowedzera huwandu hwemidziyo inogona kugadzirwa pane imwechete wafer, nekudaro ichidzikisa mutengo padanho remudziyo.
Kubva muna 2023, takaona vatengesi veSiC vakawanda vachiratidzira 8-inch wafers yekugadzira ramangwana.
6-inch wafers achiri kukosha
"Vamwe vatengesi vakuru veSiC vakasarudza kutama kubva pakungotarisa chete pa8-inch wafers uye kutarisa zvine hungwaru pane 6-inch wafers. Nepo kutamira kune 8 inch kuri pahurongwa hwemakambani mazhinji eSiC device, iyo inotarisirwa kuwedzera mukugadzirwa kweakawanda akakura 6 inch substrates - uye kuwedzera kunotevera mumakwikwi emutengo, izvo zvinogona kuita kuti vatambi veSiC vabvise hukuru hwemasendi maviri - 8 inch Mune ramangwana, semuenzaniso, makambani akaita seInfineon Technologies haasi kutora matanho ekukurumidza kuwedzera 8-inch yavo, izvo zvinopesana zvakanyanya nezano reWolfspeed. Dr. Ezgi Dogmus vakadaro.
Nekudaro, Wolfspeed yakasiyana nemamwe makambani anobatanidzwa muSiC nekuti inotariswa chete pazvinhu. Semuenzaniso, Infineon Technologies, Anson & Company uye stmicroelectronics - vanova vatungamiriri muindasitiri yemagetsi emagetsi - vanewo mabhizinesi akabudirira mumisika yesilicon uye gallium nitride.
Ichi chinhu chinokanganisawo Wolfspeed's kuenzanisa zano nevamwe vakuru veSiC vatengesi.
Vhura mamwe maapplication
Yole Intelligence inotenda kuti indasitiri yemotokari ichaita 70 kusvika ku80 muzana yemusika weSiC device ne 2023. Sezvo simba rinowedzera, zvigadziro zveSiC zvichashandiswa nyore nyore mumashandisirwo emabhizimisi akadai semagetsi emagetsi emagetsi uye magetsi, pamwe chete nemagetsi emagetsi emagetsi akadai se photovoltaic uye simba remhepo.
Zvisinei, vanoongorora paYole Intelligence vanofanotaura kuti motokari dzicharamba dziri mutyairi mukuru, uye chikamu chayo chemusika chisingatarisirwi kuchinja mumakore gumi anotevera. Izvi zvinonyanya kuitika kana matunhu achiunza zvinangwa zvemotokari yemagetsi kuti zvizadzise zvinangwa zvemamiriro ekunze zvazvino uye zviri pedyo.
Zvimwe zvinhu zvakaita sesilicon IGBT uye silicon yakavakirwa GaN inogona zvakare kuve sarudzo yeOems mumusika wemotokari. Makambani akadai seInfineon Technologies uye STMicroelectonics ari kuongorora aya ma substrates, kunyanya nekuti anodhura-anokwikwidza uye haadi machira akazvipira. Yole Intelligence yanga ichitarisa zvakanyanya pazvinhu izvi mumakore mashoma apfuura uye inozviona sevanogona kukwikwidza kuSiC mune ramangwana.
Kuenda kwaWolfspeed muEurope ine 8-inch yekugadzira kugona pasina mubvunzo kunonangana nemusika weSiC mudziyo, uyo parizvino unotongwa neEurope.
