Cov kev siv ntawm silicon nitride substrate nyob rau hauv cov cuab yeej semiconductor tsuas yog tau txais los ntawm nws cov cua sov zoo heev thiab kub tsis kam.
1. Thermal conductivity
Thaum tshav kub disspipation kev ua tau zoo: semiconductor cov cuab yeej tsim ntau qhov kub thaum ua haujlwm. Lub siab thermal conductivity ntawm silicon nitride submitates kev ua kom sov thiab faib cov khoom kub ntawm lub ntaus ntawv thiab txhim kho nws cov ruaj khov thiab kev ntseeg tau.
Kev Tswj Cov Thermal: Hauv kev siv hluav taws xob siab, xws li lub igt module ntawm hluav taws xob tsheb tuaj yeem tswj hwm cov cua sov, thiab zam kev puas tsuaj rau lub cuab yeej vim tias overheating.
Thermal Ua Haujlwm Termal: Lub siab thermal conductivity thiab tsawg thermal nthuav coefficient ntawm silicon nitride sublicate ua rau nws qhia tau zoo heev thorkal kev ua haujlwm hauv cov txheej txheem thermal. Qhov no yog qhov tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau hloov nquag thiab ua cov kev hloov pauv sai (piv txwv li, coj teeb pom kev zoo).
2. Kev kub siab ua tau zoo
Kev kub siab ruaj khov: Silicon nitride substrates tseem tswj hwm lawv cov khoom siv hluav taws xob ntawm cov cuab yeej kub, uas yog qhov tseem ceeb rau cov cuab yeej siv hluav taws xob ntau tshaj plaws. Piv txwv li, nyob rau hauv lub cav cav tswj cov qauv, cov silicon nitride substrate tuaj yeem ua kom cov cuab yeej ua haujlwm tau kub.
Antioxidant Khoom: Cov silicon nitride substrate muaj cov tshuaj tiv thaiv zoo heev thiab tsis tuaj yeem ua rau oxidized rau hauv ib puag ncig txog 1400 degree. Qhov no muab nws lub neej kev pab ntau dua thiab kev ntseeg siab dua nyob rau hauv cov ntawv thov kub siab.
Thermal nthuav dav: Lub thermal nthuav coefficient ntawm silicon nitride substrate ntais ntawv ntau yam khoom siv (piv txwv li cov kab nrib pleb thiab cov kab nrib pleb
Kev Ua Haujlwm Kub-: Silicon nitride substrate tuaj yeem tswj nws cov qauv thiab kev ua tau zoo thaum lub sijhawm ntsuas kub uas yuav tsum muaj kev kho kub siab lossis kev kho cua sov
Zuag qhia tag nrho, lub siab thermal conductivity thiab cov kub ua hauj ntawm silicon nitride detection cia cov cuab yeej kub siab thiab ntau dua xav tau, yog li txhim kho lawv cov kev ua tau zoo tag nrho. Ntxiv mus, los ntawm kev kub kub ua tau zoo thiab kub ua tsis tau zoo, cov khoom ua haujlwm ntev ntawm cov khoom siv ua ke thiab cov nuj nqis txo thiab hloov tus nqi. Raws li cov cwj pwm no, cov silicon nitride substrate muaj ntau ntawm cov ntawv thov, xws li aerospace, tub rog, kev tswj hwm, thiab lub zog hluav taws xob.
