Zophika za SiC ndi ma semiconductors opangidwa kuchokera ku silicon carbide. Izi zidapangidwa mu 1893 ndipo ndizoyenera kugwiritsa ntchito zosiyanasiyana. Makamaka oyenera Schottky diode, chotchinga chotchinga Schottky diode, masiwichi ndi metal-oxide-semiconductor field-effect transistors. Chifukwa cha kuuma kwake kwakukulu, ndi chisankho chabwino kwambiri pazigawo zamagetsi zamagetsi.
Pakalipano, pali mitundu iwiri ikuluikulu ya zowotcha za SiC. Yoyamba ndi yopyapyala yopukutidwa, yomwe ndi kansalu kakang'ono ka silicon carbide. Amapangidwa ndi makristalo apamwamba a SiC ndipo amatha kukhala 100mm kapena 150mm m'mimba mwake. Amagwiritsidwa ntchito pazida zamagetsi zamagetsi. Mtundu wachiwiri ndi epitaxial crystal silicon carbide wafer. Mtundu woterewu umapangidwa powonjezera gawo limodzi la silicon carbide makhiristo pamwamba. Njirayi imafuna kuwongolera molondola kwa makulidwe a zinthuzo ndipo imadziwika kuti N-mtundu wa epitaxy.
Mtundu wotsatira ndi beta silicon carbide. Beta SiC imapangidwa pa kutentha pamwamba pa 1700 digiri Celsius. Ma alpha carbides ndi omwe amapezeka kwambiri ndipo amakhala ndi mawonekedwe a kristalo a hexagonal ofanana ndi wurtzite. Fomu ya beta ndi yofanana ndi diamondi ndipo imagwiritsidwa ntchito pazinthu zina. Zakhala chisankho choyamba pamagetsi amagetsi omaliza kumaliza. Otsatsa angapo a gulu lachitatu la silicon carbide wafer akugwira ntchito pazatsopanozi.
ZMSH SiC wafers ndi zida zodziwika bwino za semiconductor. Ndizinthu zapamwamba za semiconductor zomwe ndizoyenera kugwiritsa ntchito zambiri. ZMSH silicon carbide wafers ndi zinthu zothandiza kwambiri pazida zosiyanasiyana zamagetsi. ZMSH imapereka zowotcha zamtundu wapamwamba za SiC ndi magawo ang'onoang'ono. Amapezeka mumtundu wa N ndi mafomu osatsekeredwa.
2---Silicon Carbide: Pofika nthawi yatsopano yophika
Thupi ndi mawonekedwe a silicon carbide
Silicon carbide ili ndi mawonekedwe apadera a kristalo, pogwiritsa ntchito mawonekedwe ozungulira a hexagonal ofanana ndi diamondi. Kapangidwe kameneka kamathandizira silicon carbide kukhala ndi matenthedwe abwino kwambiri komanso kutentha kwambiri. Poyerekeza ndi zida zachikhalidwe za silicon, silicon carbide ili ndi mpata wokulirapo wa band, womwe umapereka malo apamwamba a ma elekitironi, zomwe zimapangitsa kuti ma elekitironi aziyenda komanso kutsika pang'ono kwaposachedwa. Kuphatikiza apo, silicon carbide imakhalanso ndi liwiro lapamwamba la electron machulukitsidwe amadzimadzi komanso kutsika kwa zinthu zomwezo, zomwe zimapereka magwiridwe antchito abwino kwambiri pakugwiritsa ntchito mphamvu zambiri.
Milandu yogwiritsira ntchito ndi chiyembekezo cha silicon carbide wafers
Ntchito zamagetsi zamagetsi
Silicon carbide wafer ili ndi chiyembekezo chogwiritsa ntchito kwambiri pamagetsi amagetsi. Chifukwa cha kusuntha kwawo kwa ma elekitironi apamwamba komanso kutenthetsa bwino kwambiri, zowotcha za SIC zitha kugwiritsidwa ntchito kupanga zida zosinthira mphamvu zamphamvu kwambiri, monga ma module amagetsi amagalimoto amagetsi ndi ma inverters a solar. Kukhazikika kwa kutentha kwa ma silicon carbide wafers kumathandizira kuti zidazi zizigwira ntchito m'malo otentha kwambiri, zomwe zimapatsa mphamvu komanso kudalirika.
Mapulogalamu a Optoelectronic
M'munda wa zida za optoelectronic, zowotcha za silicon carbide zikuwonetsa ubwino wawo wapadera. Silicon carbide zinthu zili ndi mipata yotalikirapo ya bandi, yomwe imathandiza kuti ikwaniritse mphamvu zambiri za photonon komanso kutayika kwa kuwala kochepa pazida za optoelectronic. Zophika za silicon carbide zitha kugwiritsidwa ntchito pokonzekera zida zoyankhulirana zothamanga kwambiri, ma photodetectors ndi ma laser. Kutentha kwake kwabwino kwambiri komanso kuchepa kwa kristalo wocheperako kumapangitsa kuti ikhale yabwino pokonzekera zida zapamwamba za optoelectronic.
Outlook
Pakuchulukirachulukira kwa zida zamagetsi zamagetsi zogwira ntchito kwambiri, zowotcha za silicon carbide zili ndi tsogolo labwino ngati chinthu chokhala ndi zinthu zabwino kwambiri komanso kuthekera kogwiritsa ntchito mokulirapo. Ndi kuwongolera kosalekeza kwaukadaulo wokonzekera ndikuchepetsa mtengo, kugwiritsa ntchito malonda a silicon carbide wafers kudzalimbikitsidwa. Zikuyembekezeka kuti m'zaka zingapo zikubwerazi, zowotcha za silicon carbide zidzalowa pang'onopang'ono pamsika ndikukhala chisankho chachikulu chamagetsi apamwamba, ma frequency apamwamba komanso kutentha kwambiri.
3---Kusanthula mozama kwa msika wa SiC wafer ndi machitidwe aukadaulo
Kusanthula mozama kwa oyendetsa msika wa silicon carbide (SiC).
Kukula kwa msika wa silicon carbide (SiC) wafer kumakhudzidwa ndi zinthu zingapo zofunika, ndipo kusanthula mozama kwazomwe zikuchitika pamsika ndikofunikira. Nazi zina mwazoyambitsa msika:
Kupulumutsa mphamvu ndi kuteteza chilengedwe: Kuchita bwino kwambiri komanso kugwiritsa ntchito mphamvu zochepa kwa zida za silicon carbide kumapangitsa kuti ikhale yotchuka pantchito yopulumutsa mphamvu komanso kuteteza chilengedwe. Kufunika kwa magalimoto amagetsi, ma inverter a solar ndi zida zina zosinthira mphamvu zikuyendetsa kukula kwa msika wama silicon carbide wafers chifukwa zimathandizira kuchepetsa kuwononga mphamvu.
Mapulogalamu a Power Electronics: Silicon carbide imaposa mphamvu zamagetsi zamagetsi ndipo imatha kugwiritsidwa ntchito mumagetsi amagetsi pansi pa kupanikizika kwambiri komanso kutentha kwambiri. Ndi kutchuka kwa mphamvu zongowonjezwdwa komanso kulimbikitsa kusintha kwamagetsi, kufunikira kwa ma silicon carbide wafers pamsika wamagetsi amagetsi kukukulirakulira.
SiC wafers mtsogolo kupanga ukadaulo waukadaulo kusanthula mwatsatanetsatane
Kupanga kwakukulu ndikuchepetsa mtengo: Kupanga zowotcha zamtsogolo za SiC kudzayang'ana kwambiri pakupanga kwakukulu komanso kuchepetsa mtengo. Izi zikuphatikiza njira zokulirapo monga chemical vapor deposition (CVD) ndi physical vapor deposition (PVD) kuti muwonjezere zokolola komanso kuchepetsa ndalama zopangira. Kuphatikiza apo, kukhazikitsidwa kwa njira zopangira mwanzeru komanso zodzipangira zokha zikuyembekezeka kupititsa patsogolo luso.
Kukula kwatsopano ndi mawonekedwe ake: Kukula ndi mawonekedwe a zowotcha za SiC zitha kusintha mtsogolomo kuti zikwaniritse zosowa zamapulogalamu osiyanasiyana. Izi zitha kuphatikiza zowotcherera zokulirapo, zopingasa, kapena zowotcha zamitundu ingapo kuti zipereke kusinthasintha kwapangidwe komanso magwiridwe antchito.
Kugwiritsa Ntchito Mphamvu Zamagetsi ndi Kupanga Zobiriwira: Kupanga zowotcha za SiC mtsogolomu kudzagogomezera kwambiri mphamvu zamagetsi komanso kupanga zobiriwira. Mafakitole opangidwa ndi mphamvu zongowonjezwdwanso, zobiriwira, zobwezeretsanso zinyalala komanso njira zopangira mpweya wocheperako zitha kukhala njira zopangira.
