TaC dahaarka lehqoto dheer ee ultraviolet LED graphite base waxa loola jeedaa habka hagaajinta waxqabadka iyo xasiloonida aaladda iyada oo la dhigayo aDaahan TaCon saldhigga graphite inta lagu guda jiro diyaarinta ee qoto dheer ultraviolet qalab LED. Dahaarkani wuxuu wanaajin karaa waxqabadka kuleylka kuleylka, iska caabinta heerkulka sare iyo caabbinta oksaydhka ee aaladda, taas oo hagaajinaysa waxtarka iyo kalsoonida aaladda LED. Qalab qotodheer oo ultraviolet LED ah ayaa inta badan loo isticmaalaa meelo gaar ah, sida jeermiska, daaweynta iftiinka, iwm, kuwaas oo leh shuruudo sare oo loogu talagalay xasilloonida iyo waxqabadka qalabka. Codsiga eeGaraafyada dahaarka leh ee TaCsaldhigga ayaa si wax ku ool ah u wanaajin kara cimri dhererka iyo waxqabadka qalabka, isagoo siinaya taageero muhiim u ah horumarinta tignoolajiyada qoto dheer ee ultraviolet LED.
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.
