Zosiyana ndi zida za S1C discrete zomwe zimatsata ma voliyumu apamwamba, mphamvu zambiri, ma frequency apamwamba komanso mawonekedwe a kutentha kwambiri, cholinga chofufuzira cha SiC Integrated circuit makamaka ndikupeza kutentha kwa digito kwamphamvu yanzeru ya ICs control circuit. Monga SiC Integrated dera kwa munda magetsi otsika kwambiri, kotero chikoka cha microtubules chilema adzakhala kwambiri kutha, ichi ndi chidutswa choyamba cha monolithic SiC Integrated ntchito amplifier Chip anatsimikiziridwa, kwenikweni yomalizidwa mankhwala ndi anatsimikiza ndi zokolola ndi apamwamba kwambiri. kuposa microtubules zolakwika, choncho, zochokera SiC zokolola chitsanzo ndi Si ndi CaAs zakuthupi n'zoonekeratu zosiyana. Chipchi chimakhazikitsidwa ndi ukadaulo wa NMOSFET wochepa. Chifukwa chachikulu ndichakuti kusuntha kwabwino kwa ma SiC MOSFETs akumbuyo ndikotsika kwambiri. Kuti mupititse patsogolo kuyenda kwa Sic, ndikofunikira kuwongolera ndikuwongolera matenthedwe amtundu wa Sic.
Yunivesite ya Purdue yachita ntchito zambiri pamabwalo ophatikizika a SiC. Mu 1992, fakitale idapangidwa bwino potengera njira yosinthira 6H-SIC NMOSFETs monolithic digito Integrated circuit. Chip chili ndi osati chipata, kapena ayi chipata, pa kapena chipata, kauntala ya binary, ndi mabwalo a adder theka ndipo amatha kugwira ntchito bwino pa kutentha kwa 25 ° C mpaka 300 ° C. Mu 1995, ndege yoyamba ya SiC MESFET Ics idapangidwa pogwiritsa ntchito ukadaulo wa vanadium jakisoni wodzipatula. Mwa kuwongolera ndendende kuchuluka kwa vanadium jekeseni, SiC yotsekera imatha kupezeka.
M'mabwalo a digito, mabwalo a CMOS ndi okongola kwambiri kuposa mabwalo a NMOS. Mu Seputembala 1996, gawo loyamba lophatikizika la digito la 6H-SIC CMOS linapangidwa. Chipangizochi chimagwiritsa ntchito jekeseni wa N-order ndi wosanjikiza wa oxide, koma chifukwa cha zovuta zina, chip PMOSFETs threshold voltage ndi okwera kwambiri. Mu Marichi 1997 popanga dera lachiwiri la SiC CMOS. Ukadaulo wa jakisoni wa P msampha ndi wosanjikiza wa kukula kwamafuta amatengedwa. Mphamvu yamagetsi ya PMOSEFT yomwe imapezedwa ndi kukonza njira ndi pafupifupi -4.5V. Mabwalo onse pa chip amagwira ntchito bwino kutentha kwa firiji mpaka 300 ° C ndipo amayendetsedwa ndi magetsi amodzi, omwe amatha kukhala paliponse kuyambira 5 mpaka 15V.
Ndi kusintha kwa gawo laling'ono la gawo lapansi, mabwalo ophatikizika azigwira ntchito komanso zokolola zambiri adzapangidwa. Komabe, pamene mavuto a zinthu za SiC ndi ndondomeko athetsedweratu, kudalirika kwa chipangizo ndi phukusi kudzakhala chinthu chachikulu chomwe chikukhudza magwiridwe antchito a SiC ophatikizana ndi kutentha kwambiri.
