Semicera's 4 "6" Semi-Insulating SiC Substrate yog cov khoom siv zoo tsim los ua kom tau raws li cov kev cai nruj ntawm RF thiab cov khoom siv hluav taws xob. Lub substrate combines cov thermal conductivity zoo heev thiab siab tawg voltage ntawm silicon carbide nrog semi-insulating zog, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev tsim cov khoom siv semiconductor siab heev.
4 "6" Semi-Insulating SiC Substrate yog ua tib zoo tsim los xyuas kom meej cov khoom siv purity siab thiab ua haujlwm zoo ib yam. Qhov no ua kom ntseeg tau tias lub substrate muab cov hluav taws xob tsim nyog nyob rau hauv RF li xws li amplifiers thiab transistors, thaum tseem muab cov thermal efficiency yuav tsum tau rau high-power daim ntaub ntawv. Qhov tshwm sim yog ntau yam substrate uas tuaj yeem siv rau hauv ntau yam khoom siv hluav taws xob ua haujlwm siab.
Semicera paub txog qhov tseem ceeb ntawm kev muab cov khoom siv txhim khu kev qha, tsis muaj qhov tsis xws luag rau kev siv cov khoom siv hluav taws xob tseem ceeb. Peb 4 "6" Semi-Insulating SiC Substrate yog tsim los siv cov txheej txheem tsim khoom uas txo cov khoom siv lead ua thiab txhim kho cov khoom sib xws. Qhov no ua rau cov khoom siv los txhawb kev tsim cov khoom siv nrog kev ua tau zoo, ruaj khov, thiab lub neej ntev.
Semicera kev cog lus rau kev ua tau zoo ua kom peb 4 "6" Semi-Insulating SiC Substrate muab kev ntseeg tau thiab ua tau zoo nyob thoob plaws ntau yam kev siv. Txawm hais tias koj tab tom tsim cov cuab yeej siv hluav taws xob ntau lossis cov kev daws teeb meem siv hluav taws xob, peb cov khoom siv hluav taws xob semi-insulating SiC muab lub hauv paus rau kev ua tiav ntawm cov khoom siv hluav taws xob txuas ntxiv mus.
