Mtengo Wapadera wa Green Silicon Carbide Micropowder mu Makampani Opanga Ma Semiconductor
Makampani opanga zinthu zamagetsi nthawi zonse akhala akugwirizana ndi ukadaulo wapamwamba, ndipo anthu nthawi zambiri amakambirana nkhani zapamwamba monga makina ojambulira zithunzi ndi kapangidwe ka ma chip. Komabe, mkati mwa makampaniwa, zinthu zina zosafunikira kwenikweni zimakhala ndi gawo lofunika kwambiri.Ufa wobiriwira wa silicon carbidendi chimodzi mwa zinthu zimenezi. Lero, tiyeni tikambirane za zinthu zapaderazi, zomwe zikugwira ntchito mwakachetechete popanga zinthu zopangidwa ndi semiconductor.
Ndiyambe ndi nkhani yosangalatsa. Chaka chatha, ndinapita ku chiwonetsero cha malonda cha mafakitale a semiconductor. Pa malo osungiramo zinthu odziwika bwino, mainjiniya angapo anali kukambirana mosangalala za chipangizo chopera. Pomvetsera mwatcheru, ndinkawamva akutchula mobwerezabwereza kuti "green silicon carbide micropowder." Ndinadabwa panthawiyo; zinkamveka ngati chopopera chachikhalidwe cha mafakitale, ndiye zingalumikizidwe bwanji ndi ma semiconductor olondola? Pambuyo pake, ndinazindikira kuti mumakampani awa, zinthuzo zikagwiritsidwa ntchito mosavuta, zimakhala zofunika kwambiri.
Kodi ufa wobiriwira wa silicon carbide micropowder ndi chiyani kwenikweni? Mwachidule, ndi chinthu cholimba kwambiri chopangidwa ndi anthu, chomwe chimasungunuka mu uvuni wamagetsi wotentha kwambiri kuchokera ku zinthu zopangira monga mchenga wa quartz ndi petroleum coke. Dzina lake limatchedwa chifukwa cha kuyera kwake kwakukulu komanso mtundu wobiriwira wosiyana. Musanyoze tinthu tating'onoting'onoti; kuuma kwawo ndi kwachiwiri kuposa diamondi, komabe ali ndi kukhazikika kwa kutentha komanso kusagwira ntchito kwa mankhwala.
Mu kupanga ma semiconductor, kusalala kwa wafer kumatsimikizira mwachindunji kuchuluka kwa chip. Izi zikutifikitsa ku luso lofunika kwambiri lakabide wobiriwira wa silikoniufa wa micropowder: kupukuta kwa makina a mankhwala (CMP). Lao Zhang, injiniya wa makina opangira ma wafer, akugwiritsa ntchito fanizo lomveka bwino: “Zili ngati kupatsa wafer 'mankhwala a nkhope'—kuchotsa matuza ndi kusafanana popanda kusiya mikwingwirima. Ufa wa microcrystalline wobiriwira wa silicon carbide uli ngati tinthu tating'onoting'ono ta microcrystalline mu chisamaliro chapamwamba cha khungu—wofatsa koma wogwira mtima.” Zoonadi, popanga ma chip, ngakhale magawo khumi a micron osafanana angayambitse dera lalifupi kapena lotseguka.
Kusamalira kutentha ndi vuto lalikulu mumakampani opanga ma semiconductor. Pamene kuphatikiza ma chips kukuchulukirachulukira, kutayika kwa kutentha kumawonjezeka kwambiri.Ufa wobiriwira wa silicon carbideali ndi luso lapadera pankhaniyi: kuwonjezera pa zinthu zoyendetsera kutentha kumathandizira kwambiri kutayikira kwa kutentha. Mainjiniya wa kutentha ku kampani yotchuka ya ma chips anandiuza kuti, "Tsopano timagwiritsa ntchito ufa wapadera wobiriwira wa silicon carbide mu phala lathu lapamwamba la kutentha, lomwe limathandizira kutayikira kwa kutentha ndi zoposa 20%. Izi zimapulumutsa moyo muukadaulo wa 5nm ndi 3nm."
Ufa wa silicon carbide wobiriwira ndi wofunika kwambiri popanga zida za semiconductor. Zinthu zambiri zofunika kwambiri mu makina a lithography ndi makina odulira, zomwe zingawononge ndalama zokwana mamiliyoni ambiri a yuan, zimafuna kulondola kwambiri kwa makina opangira. Mwachitsanzo, makina owunikira a makina a lithography amafuna kusalala kwambiri kwa galasi, zomwe zimapangitsa kuti pakhale kugwiritsa ntchito ufa wa silicon carbide wobiriwira.kupukusa molondola. Katswiri wina wazaka 20 zakuntchito anati, "Kugwiritsa ntchito chipangizochi n'kovuta kwambiri. Kukula kwa tinthu tating'onoting'ono, kuchuluka kwa tinthu tating'onoting'ono, ndi pH zonse ziyenera kulamulidwa bwino; ngakhale kusintha pang'ono kungakhudze zotsatira zake."
Ndikofunikira kudziwa kuti chifukwa cha kukwera kwa zipangizo za semiconductor za m'badwo wachitatu, green silicon carbide micropowder yapeza ntchito yatsopano. Zipangizo za semiconductor zochokera ku silicon carbide zokha zimafuna green silicon carbide micropowder kuti zipere ndi kupukuta panthawi yokonza. Ndi nthawi yosangalatsa—kugwiritsa ntchito silicon carbide pokonza silicon carbide. Mtsogoleri waukadaulo wa kampani yatsopano ya semiconductor anamwetulira nati, “Zili ngati kugwiritsa ntchito diamondi kudula diamondi; kokha ngati zipangizo zimatha kumvetsetsana.”
Ufa wa silicon carbide wobiriwira umagwiranso ntchito yapadera pakuwongolera khalidwe. Mafakitale opanga zinthu zamagetsi amafunika kukonza zida nthawi zonse, makamaka kuyeretsa mizere yotumizira ndi zipinda zoyankhira. Chifukwa ufa wa silicon carbide wobiriwira ndi wopanda mankhwala ndipo subweretsa zinthu zatsopano zodetsa, ndiye chinthu chomwe chimakonda kwambiri poyeretsa. Mainjiniya wokonza zinthu adavumbulutsa kuti, "Poyerekeza ndi zinthu zina zochotsera,ufa wobiriwira wa silicon carbide micropowdersichisiya ma ayoni achitsulo pa makoma amkati mwa zipangizo, zomwe ndizofunikira kwambiri kuti malo azikhala oyera popanga ma chip.
Zachidziwikire, chilichonse chili ndi malo oti chiwongoleredwe. Mavuto omwe akukumana nawo pakadali pano ndi silicon carbide micropowder wobiriwira makamaka ndi kuwongolera mtengo ndi kusinthasintha kwa khalidwe. Njira yovuta yopangira komanso kugwiritsa ntchito mphamvu zambiri zimapangitsa kuti mtengo wake ukhale wokwera. Kuphatikiza apo, kusinthasintha kwa mitundu yonse ndi nkhani yofunika kwambiri kwa ogwiritsa ntchito. Komabe, makampani angapo otsogola akunyumba akuyamba kale kuthana ndi mavutowa, pang'onopang'ono kuchepetsa kusiyana kwa zinthu zomwe zimatumizidwa kunja mwa kukonza njira zopangira ndi machitidwe oyang'anira khalidwe.
Poyang'ana mtsogolo, pamene ukadaulo wa semiconductor ukupita patsogolo kupita ku njira zazing'ono komanso milingo yowonjezereka yolumikizirana, kufunikira kwa ufa wobiriwira wa silicon carbide kudzapitirira kukula. Izi ndi zoona makamaka m'magawo omwe akutukuka kumene monga ma chip anzeru opangira zinthu, ma chip olumikizirana a 5G, ndi ma chip odziyendetsa okha, zomwe zimapangitsa kuti pakhale kufunikira kwakukulu pakuwongolera bwino komanso magwiridwe antchito otaya kutentha. Izi zimatsegula mitundu yambiri ya ntchito za ufa wobiriwira wa silicon carbide.
Ndikukumbukira katswiri wina wamakampani akuti, “Makampani opanga zinthu za semiconductor ali ngati phiri lopanda madzi. Zimene anthu amaona ndi kapangidwe ka chip kokha ndi kupanga zinthu zazikulu pamwamba pa nthaka, pomwe zipangizo, njira, ndi zida zomwe zili pansi pa nthaka ndi maziko omwe amathandizira makampani onse.” Ufa wobiriwira wa silicon carbide ndi gawo lofunika kwambiri la zinthu zoyambira izi. Sizingakhale zokopa maso ngati makina ojambulira, koma ndi zinthu “zosaoneka” izi zomwe zimathandiza chitukuko cha makampani onse opanga zinthu za semiconductor.
Nthawi ina mukagwiritsa ntchito foni yam'manja kapena kuyendetsa galimoto yanzeru, mwina ganizirani kuti kumbuyo kwa zinthu zamakono izi kuli zinthu "zosadzikuza" monga ufa wobiriwira wa silicon carbide. Kupatula apo, kupita patsogolo kwa mafakitale onse sikungasiyanitsidwe ndi "ngwazi zodzipereka zomwe zili kumbuyo kwa zochitika" izi.
