Sezvo nyika iri kukurumidza kuchinja kwayo kuenda kune tekinoroji inochengetedza nharaunda, musika wesilicon carbide (SiC) wafer uri kubuda semutambi akakosha muindasitiri ye semiconductor ine simba guru. Uchitarisirwa kukura kubva pamadhora mazana masere nemakumi maviri nemaviri nemakumi matatu nematatu emamiriyoni muna 2024 kusvika pamadhora mazana mana nemakumi maviri nemanomwe emadhora panosvika gore ra2033, musika unotarisirwa kukura nechikamu chekukura kwegore negore (CAGR) che20.11% kubva muna 2025 kusvika 2033. Kukura uku kunonyanya kukonzerwa nekuwedzera kwekushandiswa kwemotokari dzemagetsi (EVs), magetsi emagetsi, uye masisitimu esimba rinodzokororwa. Nekugona kwayo kufambisa kupisa kwakanyanya, kushivirira magetsi akawanda, uye kushanda nesimba, SiC yave chinhu chakakosha mukushandiswa kwe semiconductor ine simba guru.
Masimba Anotungamira Kukura kweMusika weSiC: MaEV neMagetsi Emagetsi
Kuwanda kuri kuita kudiwa kwemotokari dzemagetsi pasi rose (EVs) chimwe chezvinhu zvikuru zviri kukurudzira kukura kwemusika weSiC wafer. Kushanda zvakanaka kweSiC munzvimbo dzine magetsi akawanda uye kugona kwayo kutsungirira mamiriro ekupisa kwakanyanya kunoita kuti ive chinhu chakanakira zvishandiso zvemagetsi zvakaita sema inverters nema inboard chargers mumotokari dzemagetsi. Izvi zvikamu zvinobatsira kubva pakukwanisa kweSiC kubata magetsi akawandisa uye tembiricha, zvichikonzera nguva yekuchaja nekukurumidza uye kureba kwenguva refu.
Sezvo shanduko yepasi rose yekufambisa zvinhu zvisina njodzi iri kuwedzera, kudiwa kwemawafer eSiC kwakawedzera. Muna 2025, kutengeswa kwemotokari dzemagetsi pasi rose kunotarisirwa kusvika mamiriyoni 1.6, nekukura kukuru kwemusika kuchikonzerwa nenzvimbo dzakadai seAsia-Pacific, uko nyika dzakadai seChina dziri kutungamira mukushandiswa kwemaEV. Kudiwa kuri kukura kwemaEV anoshanda zvakanyanya ane kugona kuchaja nekukurumidza kwakaita kuti pave nekudiwa kukuru kwemawafer eSiC, ayo anopa mashandiro akanaka zvichienzaniswa nezvikamu zvechinyakare zvesilicon.
Simba Rinodzokororwa uye Magridhi Akangwara: Injini Itsva Yekukura yeSiC
Pamusoro pechikamu chemotokari,Mawafer eSiCzviri kushandiswa zvakanyanya mukushandiswa kwesimba rinogona kuvandudzwa, kusanganisira masisitimu esimba rezuva nemhepo. Midziyo yakavakirwa paSiC, senge ma inverter nema converters, inobvumira kushandurwa kwesimba zvinobudirira uye kudzikira kwekurasikirwa kwesimba, izvo zvakakosha pakuwedzera mashandiro emasisitimu esimba rinogona kuvandudzwa. Sezvo kusundidzira kwepasi rose kwekubvisa kabhoni kuri kuwedzera, kudiwa kwemidziyo yesimba inoshanda zvakanyanya uye isingadhuri kunotarisirwa kukura, zvichiita kuti SiC ive chinhu chakakosha muchikamu chesimba rinogona kuvandudzwa.
Uyezve, mabhenefiti eSiC mukubata mavoltage akakwira uye kushanda zvakanaka kwekupisa kunoita kuti ive yakakodzera kushandiswa mumagrid akangwara uye masisitimu ekuchengetera simba. Sezvo nyika iri kufambira mberi kune mhinduro dzekugadzira nekuchengetera simba dzakaparadzaniswa, kudiwa kwemidziyo yeSiC midiki uye inoshanda zvakanyanya kunotarisirwa kuwedzera, ichiita basa guru mukuvandudza mashandiro esimba uye kuderedza tsoka dzezvakatipoteredza.
Matambudziko: Mari Yakakwira Yekugadzira uye Zvipingamupinyi Zvekutengesa
Pasinei nekukwanisa kwayo kukuru, musika weSiC wafer unotarisana nematambudziko akati wandei. Chimwe chezvipingamupinyi zvikuru imutengo wakakwira wekugadzira weSiC. Kugadzirwa kweSiC wafers kunosanganisira kukura kwakaoma kwekristaro uye maitiro ekupukuta anoda matekinoroji epamusoro uye zvinhu zvinodhura. Nekuda kweizvozvo, mutengo weSiC wafers wakakwira zvakanyanya kupfuura wekare wesilicon wafers, izvo zvinoderedza kushandiswa kwawo mukushandiswa kunonyanya kudhura uye zvinopa matambudziko ekukwira, kunyanya kumakambani madiki nepakati e semiconductor.
Kugadzirwa kwemawafer eSiC pasi rose kunokanganiswawo nekushaikwa kwesimba rekugadzira uye kushomeka kwevashandi vane hunyanzvi mukukura kwemakristaro nekugadzira mawafer. Kugadzirwa kwemawafer eSiC emhando yepamusoro kunoda ruzivo rwakadzama nemidziyo, uye makambani mashoma pasi rose ane hunyanzvi hwekuagadzira zvakanyanya. Sezvo kudiwa kweSiC kuri kuramba kuchikura, mawafer anotarisana nekumanikidzwa kwekuwedzera kugona kwekugadzira, kunyanya mumaindasitiri akadai semotokari nemagetsi anogona kushandiswazve uko kudiwa kuri kuwedzera nekukurumidza.
Kuvandudzwa muKugadzira Semiconductor Kunosimudzira Kukura kweSiC
Kuvandudzwa kuri kuenderera mberi mukugadzira ma semiconductor uye matekinoroji ekugadzira ma wafer kuri kubatsira kugadzirisa mamwe ematambudziko aya. Kugadzirwa kwema wafers ane dhayamita yakakura, akadai sema wafers eSiC ane dhayamita 6 ne 8, kwakabvumira goho rakakwirira uye mitengo yakaderera, zvichiita kuti SiC ive nyore kushandiswa mumhando dzakasiyana-siyana dzemashandisirwo, kusanganisira mota, maindasitiri, uye zvigadzirwa zvemagetsi zvevatengi.
Pamusoro pezvo, kufambira mberi mukugadzira matekiniki ekugadzira makristaro, akadai se chemical vapor deposition (CVD) uye physical vapor transport (PVT), kwakaita kuti mhando yewafer ive nani, zvikanganiso zvishoma, uye goho rekugadzira riwedzere. Izvi zviri kubatsira kudzikisa mutengo weSiC wafers uye kuwedzera kushandiswa kwadzo mumabasa epamusoro.
Semuenzaniso, kuumbwa kwefekitori itsva dzekugadzira ma semiconductor dzakanangana nekugadzira mawafer eSiC, kunyanya mumisika iri kusimukira, kuchawedzera kuwanikwa kwezvikamu zveSiC. Sezvo kugadzirwa kuri kuwedzera uye matekiniki matsva ekugadzira achibuda, mawafer eSiC achave akachipa uye anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana.
Kutarisa Mberi: Basa Riri Kuwedzera reSiC muMishonga Yepamusoro-soro
Pasinei nematambudziko aripo parizvino maererano nemitengo uye zvipingamupinyi zvekutengesa, tarisiro yenguva refu yemusika weSiC wafer yakanaka kwazvo. Sezvo nyika ichiramba ichichinja kuenda kune mhinduro dzesimba rinogara kwenguva refu uye kutakurwa kwezvakatipoteredza, kudiwa kwemidziyo yesimba inoshanda zvakanyanya uye inoshanda zvakanyanya kucharamba kuchikura. Hunhu hwakanaka hweSiC maererano nekutarisira kupisa, kushivirira magetsi, uye kushanda zvakanaka kwesimba zvinoita kuti ive chinhu chinosarudzwa chemagetsi emagetsi echizvarwa chinotevera, masisitimu esimba rinogona kudzorerwa, uye mota dzemagetsi.
Mukupedzisa, kunyange hazvo musika weSiC wafer uchitarisana nezvipingamupinyi, mukana wayo wekukura muzvikamu zvemotokari, simba rinogona kudzorerwa, uye magetsi emagetsi haurambiki. Nekuvandudzwa kuri kuenderera mberi muhunyanzvi hwekugadzira uye kugona kwakawedzerwa kwekugadzira, SiC yagadzirira kuva chinhu chakakosha chechizvarwa chinotevera chezvishandiso zve semiconductor zvinoshanda zvakanyanya. Sezvo kudiwa kuri kuramba kuchikwira, SiC ichaita basa rakakosha mukutungamira ramangwana retekinoroji inochengetedza nguva.
