Chiyambi chaSilicon Carbide
Silicon carbide (SIC) ili ndi kachulukidwe ka 3.2g/cm3. Natural silicon carbide ndiyosowa kwambiri ndipo imapangidwa makamaka ndi njira yopangira. Malinga ndi magulu osiyanasiyana a kristalo, silicon carbide imatha kugawidwa m'magulu awiri: α SiC ndi β SiC. Semiconductor yachitatu yomwe imayimiridwa ndi silicon carbide (SIC) imakhala ndi ma frequency apamwamba, okwera kwambiri, mphamvu zambiri, kukana kuthamanga kwambiri, kukana kutentha kwambiri komanso kukana kwamphamvu kwa radiation. Ndikoyenera pazofunikira zazikulu zakusunga mphamvu ndi kuchepetsa umuna, kupanga mwanzeru komanso chitetezo chazidziwitso. Ndikuthandizira luso lodziyimira pawokha ndi chitukuko ndi kusintha kwa kulumikizana kwa m'badwo watsopano, magalimoto amagetsi atsopano, masitima apamtunda othamanga, intaneti yamagetsi ndi mafakitale ena Zida zotsogola ndi zida zamagetsi zakhala cholinga chaukadaulo wapadziko lonse lapansi wa semiconductor ndi mpikisano wamakampani. . Mu 2020, machitidwe azachuma ndi malonda padziko lonse lapansi ali munthawi yakukonzanso, ndipo chilengedwe chamkati ndi kunja kwachuma cha China ndizovuta komanso zovuta, koma msika wachitatu wa semiconductor padziko lapansi ukukula motsutsana ndi zomwe zikuchitika. Ziyenera kuzindikirika kuti msika wa silicon carbide walowa gawo latsopano lachitukuko.
Silicon carbidentchito
Silicon carbide ntchito mu semiconductor makampani silicon carbide semiconductor makampani unyolo makamaka silicon carbide mkulu chiyero ufa, single galasi gawo lapansi, epitaxial, chipangizo mphamvu, ma CD ma module ndi ntchito terminal, etc.
1. gawo limodzi la kristalo ndizomwe zimagwiritsidwa ntchito, zopangira zinthu komanso kukula kwa epitaxial gawo lapansi la semiconductor. Pakalipano, njira zokulirapo za SiC single crystal zikuphatikizapo kutengerapo kwa gasi (PVT), gawo lamadzimadzi (LPE), kutentha kwapadera kwa vapor deposition (htcvd) ndi zina zotero. 2. epitaxial silicon carbide epitaxial sheet imatanthawuza kukula kwa filimu imodzi ya kristalo (epitaxial wosanjikiza) ndi zofunikira zina ndi kayendetsedwe kofanana ndi gawo lapansi. Pogwiritsa ntchito, zida za wide band gap semiconductor zili pafupifupi zonse pa epitaxial layer, ndipo tchipisi ta silicon carbide tomwe timangogwiritsidwa ntchito ngati magawo, kuphatikiza zigawo za Gan epitaxial.
3. chiyero chapamwambaSiCufa ndi zinthu zopangira kukula kwa silicon carbide single crystal ndi njira ya PVT. Kuyera kwazinthu zake kumakhudza mwachindunji kukula kwa kukula ndi mphamvu zamagetsi za SiC single crystal.
4. chipangizo chamagetsi chimapangidwa ndi silicon carbide, yomwe imakhala ndi mawonekedwe a kutentha kwambiri, mafupipafupi komanso kuthamanga kwambiri. Malinga ndi mawonekedwe a chipangizocho,SiCzida zamagetsi makamaka zimaphatikizapo ma diode amagetsi ndi machubu osinthira mphamvu.
5. mu ntchito ya semiconductor ya m'badwo wachitatu, ubwino wa ntchito yomaliza ndikuti akhoza kuthandizira GaN semiconductor. Chifukwa cha ubwino wa kutembenuka kwakukulu, makhalidwe otsika otentha ndi opepuka a zipangizo za SiC, kufunikira kwa makampani akumunsi akupitirirabe, komwe kumakhala ndi chizolowezi chosintha zipangizo za SiO2. Zomwe zikuchitika pamsika wa silicon carbide zikukula mosalekeza. Silicon carbide imatsogolera msika wachitatu wa chitukuko cha semiconductor. Zam'badwo wachitatu zopangira semiconductor zidalowetsedwa mwachangu, minda yofunsira ikukulirakulira mosalekeza, ndipo msika ukukula mwachangu ndikukula kwamagetsi apagalimoto, kulumikizana kwa 5g, kuthamangitsa magetsi komanso kugwiritsa ntchito usilikali. .
