TaC dahaarka hagaha garaafyadatixraac meel dhigista lakabka khafiifka ah eetantalum carbidedusha sare ee giraanta hagaha garaafka si loo hagaajiyo caabbinta xidhashada, caabbinta heerkulka sare iyo xasilloonida kiimikada. Daahan waxaa badanaa lagu sameeyaa dusha giraanta hagaha garaafka iyadoo la adeegsanayo farsamooyin ay ka mid yihiin kaydinta uumiga jirka (PVD) ama kaydinta uumiga kiimikada (CVD).
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.
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.
Tilmaamaha ugu muhiimsan ee TaC-ga dahaarka leh ee hagaha hagaha garaafyada waxaa ka mid ah:
1. Iska caabbinta heerkulka sare: Daahan TaC waxay leedahay xasillooni heerkul sare oo heer sare ah waxayna ilaalin kartaa xasilloonida jawiga heerkulka sare.
2. Xiro iska caabin: Adagnimada sare ee lakabka khafiifka ah ee tantalum carbide waxay siinaysaa giraanta hagaha caabbinta xirashada wanaagsan waxayna kordhisaa nolosha adeeggeeda.
3. Dejinta kiimikada: Daahan TaC waxay leedahay xasillooni sare oo ka soo horjeeda daxalka kiimikada, taas oo ka dhigaysa mid ku habboon codsiyada qaar ka mid ah warbaahinta wasakhaysan.
4. Iska yaree khilaafka: Daahan TaC waxay si wax ku ool ah u yareyn kartaa khilaafka u dhexeeya giraanta hagaha garaafyada iyo qaybaha kale waxayna wanaajisaa waxtarka xirmooyinka farsamada.
