TAC coatedsib sib zog nqus ultraviolet LED graphite puag yog hais txog cov txheej txheem ntawm kev txhim kho kev ua tau zoo thiab ruaj khov ntawm cov cuab yeej los ntawm kev tso nyiajTAC txheejnyob rau hauv graphite puag thaum lub sij hawm kev npaj ntawm lub sib sib zog nqus ultraviolet LED ntaus ntawv. Cov txheej no tuaj yeem txhim kho cov cua sov ua haujlwm, qhov kub thiab txias tsis kam thiab oxidation tsis kam ntawm cov cuab yeej, yog li kev txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov cuab yeej LED. Cov khoom siv sib sib zog nqus ultraviolet LED feem ntau yog siv hauv qee qhov tshwj xeeb, xws li tshuaj tua kab mob, kho lub teeb, thiab lwm yam, uas muaj cov kev xav tau siab rau kev ruaj ntseg thiab kev ua haujlwm ntawm cov cuab yeej. Daim ntawv thov ntawmTaC coated graphitelub hauv paus tuaj yeem txhim kho kev ua haujlwm ntev thiab kev ua haujlwm ntawm lub cuab yeej, muab kev txhawb nqa tseem ceeb rau kev txhim kho ntawm kev sib sib zog nqus ultraviolet LED technology.
Semicera muab tshwj xeeb tantalum carbide (TaC) txheej rau ntau yam khoom thiab cov khoom nqa.Semicera ua txheej txheem txheej txheej ua rau tantalum carbide (TaC) txheej kom ua tiav siab purity, kub ruaj khov thiab siab tshuaj lom neeg, txhim kho cov khoom zoo ntawm SIC / GAN muaju thiab EPI txheej (Graphite coated TaC susceptor), thiab txuas ntxiv lub neej ntawm cov khoom tseem ceeb reactor. Kev siv tantalum carbide TaC txheej yog los daws qhov teeb meem ntawm ntug thiab txhim kho qhov zoo ntawm cov siv lead ua kev loj hlob, thiab Semicera tau tawg los daws cov tantalum carbide txheej tshuab (CVD), mus txog qib siab thoob ntiaj teb.
Tom qab xyoo ntawm txoj kev loj hlob, Semicera tau kov yeej cov thev naus laus zis ntawmCVD TSInrog rau kev sib koom tes ntawm R & D department. Cov kev tsis zoo no yooj yim tshwm sim hauv cov txheej txheem kev loj hlob ntawm SiC wafers, tab sis tom qab sivTaC, qhov txawv yog qhov tseem ceeb. Hauv qab no yog kev sib piv ntawm wafers nrog thiab tsis muaj TaC, nrog rau Simicera 'qhov chaw rau ib qho kev loj hlob siv lead ua.
nrog thiab tsis muaj TaC
Tom qab siv TaC (txoj cai)
Ntxiv mus, Semicera'sTaC-coated cov khoomnthuav tawm lub neej ua haujlwm ntev dua thiab muaj kev kub ntxhov ntau dua piv rauSiC coatings.Kev ntsuas ntsuas tau pom tias pebTAC coatingstuaj yeem ua haujlwm tsis tu ncua ntawm qhov kub txog li 2300 degrees Celsius rau lub sijhawm ntev. Hauv qab no yog qee qhov piv txwv ntawm peb cov qauv:
