Semicera waxay siisaa dahaarka tantalum carbide (TaC) ee khaaska ah ee qaybo kala duwan iyo sidayaal.Nidaamka dahaadhka hogaaminaya ee Semicera wuxuu awood u siinayaa dahaarka tantalum carbide (TaC) si loo gaaro nadiif sare, xasilooni heerkul sare ah iyo dulqaad kiimiko sare leh, hagaajinta tayada badeecada ee kiristaalo SIC/GAN iyo lakabyada EPISusceptor TaC dahaarka graphite), iyo kordhinta nolosha qaybaha muhiimka ah ee reactor.Isticmaalka daahan tantalum carbide TaC waa in la xaliyo dhibaatada cirifka iyo hagaajinta tayada kobaca crystal, iyo Semicera ayaa horumar ah xalliyo technology daahan carbide tantalum carbide (CVD), gaarey heerka sare ee caalamiga ah.
Iyadoo ay soo ifbaxday 8-inch silicon carbide (SiC) wafers, shuruudaha hababka kala duwan ee semiconductor waxay noqdeen kuwo sii adkeynaya, gaar ahaan hababka epitaxy halkaasoo heerkulku ka sarreyn karo 2000 darajo Celsius.Walxaha susceptor-dhaqameedka, sida graphite-ka lagu dahaadhay silikoon carbide, waxay u muuqdaan inay hoos u dhigaan heerkulkan sarreeya, carqaladeeya habka epitaxy.Si kastaba ha ahaatee, CVD tantalum carbide (TaC) ayaa si wax ku ool ah wax uga qabata arrintan, iyada oo xakamaysa heerkulka ilaa 2300 darajo Celsius oo bixisa nolol adeeg oo dheer.La xidhiidh Semicera's CVD Tantalum Carbide Dahaarka Sare Halfmoonsi aan wax badan uga baadho xalalkeena horumarsan.
Sannado badan oo horumarineed ka dib, Semicera waxay ku guulaysatay tiknoolajiyadaCVD TaCiyadoo dadaalka wadajirka ah ee waaxda R&D.Cilladaha way fududahay in ay ku dhacaan habka koritaanka SiC wafers, laakiin ka dib marka la isticmaaloTaC, farqigu waa mid muhiim ah.Hoos waxaa ku yaal isbarbardhigga waferrada leh iyo la'aanta TaC, iyo sidoo kale qaybaha Simicera ee kobaca kareemka keliya.
