Kambani yeWolfspeed Inc yekuDurham, NC, USA — iyo inogadzira zvinhu zvesilicon carbide (SiC) uye zvishandiso zvemagetsi zve semiconductor — yazivisa kuburitswa kwezvigadzirwa zvayo zve200mm SiC, zvichiratidza danho guru mubasa rayo rekukurumidzisa shanduko yeindasitiri kubva kusilicon kuenda kusilicon carbide. Mushure mekutanga kupa 200mm SiC kune vatengi vakasarudzwa, kambani iyi inoti mhinduro yakanaka uye mabhenefiti akapihwa aifanirwa kuburitswa kumusika.
Wolfspeed iri kupawo 200mm SiC epitaxy kuti ishandiswe nekukurumidza, iyo, kana yakabatana ne200mm bare wafers, inopa izvo zvinonzi kuvandudzwa uye kunaka kuri nani, zvichigonesa chizvarwa chinotevera chemidziyo yemagetsi inoshanda zvakanyanya.
"Mawafer eWolfspeed e200mm SiC anopfuura kungowedzera dhayamita yewafer - anomiririra hunyanzvi hwezvinhu hunopa simba vatengi vedu kuti vakurumidze kuronga michina yavo nechivimbo," anodaro Dr Cengiz Balkas, mukuru webhizinesi. "Nekupa mhando yepamusoro, Wolfspeed iri kugonesa vagadziri vemagetsi emagetsi kusangana nekudiwa kuri kukura kwemhinduro dzesilicon carbide dzinoshanda zvakanyanya uye dzinoshanda zviri nani."
Kuvandudzwa kwezviyero zve200mm SiC bare wafers paukobvu hwe350µm uye zvinonzi zvakawedzerwa, kushandiswa kwedoping uye kufanana kweukobvu kwe200mm epitaxy kunoita kuti vagadziri vemidziyo vakwanise kuvandudza goho reMOSFET, kukurumidzisa nguva yekutenga, uye kupa mhinduro dzinokwikwidzana mumotokari, simba rinogona kudzokororwa, maindasitiri, uye mamwe mashandisirwo anobudirira, anodaro Wolfspeed. Kufambira mberi kwezvigadzirwa nekushanda kwe200mm SiC kunogonawo kushandiswa pakudzidza kunoenderera mberi kwezvigadzirwa zve150mm SiC, kambani inowedzera.
"Kufambira mberi uku kunoratidza kuzvipira kwaWolfspeed kwenguva refu mukusimudzira miganhu yetekinoroji yezvinhu zvesilicon carbide," anodaro Balkas. "Kuburitswa uku kunoratidza kugona kwedu kufanoona zvinodiwa nevatengi, kuwedzera kudiwa, uye kupa hwaro hwezvinhu zvinoita kuti ramangwana rekushandura simba rive nyore."
