Tantalum carbide xaashida garaafyada dahaarka lehwaa maaddo garaaf ah oo leh lakab khafiif ahtantalum carbidedusha sare ee substrate-ka. Lakabka khafiifka ah ee tantalum carbide waxaa badanaa lagu sameeyaa dusha sare ee garaafyada iyadoo la adeegsanayo farsamooyinka sida kaydinta uumiga jirka (PVD) ama kaydinta uumiga kiimikada (CVD). Dahaarkani wuxuu leeyahay sifooyin aad u fiican sida qallafsanaanta sare, caabbinta xirashada aadka u fiican, iska caabinta daxalka iyo xasilloonida heerkulka sare.
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.
Faa'iidooyinka ugu muhiimsan ee xaashida graphite ee dahaarka leh ee tantalum carbide waxaa ka mid ah:
1. Iska caabin heerkul sare ah: Tantalum carbide waxay leedahay meel dhalaalaysa oo heerkulkeedu sarreeyo iyo xasilloonida heerkulka sare, taas oo ka dhigaysa xaashida garaafyada dahaarka leh ee ku habboon isticmaalka jawiga heerkulka sare.
2. Iska caabinta daxalka: Tantalum carbide daahan waxay u adkeysan kartaa nabaad guurka walxo badan oo kiimikaad ah oo kordhiya nolosha adeegga maaddada.
3. Qallafsanaanta sare: Qalafsanaanta sare ee lakabka khafiifka ah ee tantalum carbide waxay bixisaa caabbinta xirashada wanaagsan waxayna ku habboon tahay codsiyada u baahan caabbinta xirashada sare.
4. Degganaanshaha kiimikaad: Daahan Tantalum carbide waxay leedahay xasillooni aad u fiican si ay u daxaloobaan kiimikada waxayna ku habboon tahay isticmaalka qaar ka mid ah warbaahinta daxalka.
