Raws li kev sib xyaw ua ke tau dhau los ua kev lag luam hauv lub tebchaws, ntau cov khoom siv semiconductor tau tshawb fawb thiab tsim, thiab Aluminium Nitride yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv semiconductor.
Aluminium Nitride Performance Yam ntxwv
Aluminium Nitride (AlN) muaj cov yam ntxwv ntawm lub zog siab, siab ntim resistivity, siab rwb thaiv tsev voltage, coefficient ntawm thermal expansion, zoo txuam nrog silicon, thiab lwm yam. Nws tsis yog tsuas yog siv raws li ib tug sintering pab los yog reinforcing theem rau structural ceramics tab sis kuj siv. Nyob rau hauv lub tshav pob ntawm ceramic hluav taws xob substrates thiab ntim cov ntaub ntawv, uas tau booming nyob rau hauv xyoo tas los no, thiab nws cov kev ua tau zoo tshaj ntawm Alumina. Aluminium Nitride ceramics muaj kev ua tau zoo tag nrho, zoo tagnrho rau semiconductor substrates thiab cov khoom ntim khoom, thiab muaj peev xwm siv tau hauv kev lag luam hluav taws xob.
Kev siv ntawm Aluminium Nitride
1. Daim ntawv thov Piezoelectric ntaus ntawv
Aluminium Nitride muaj kev tiv thaiv siab, siab thermal conductivity, thiab qis coefficient ntawm kev nthuav dav zoo ib yam li silicon, uas yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob kub thiab hluav taws xob siab.
2. Cov ntaub ntawv ntim khoom siv hluav taws xob
Beryllium Oxide, Alumina, Silicon Nitride, thiab Aluminium Nitride yog ib co ntawm cov khoom siv feem ntau siv rau ceramic substrates.
Ntawm cov ntaub ntawv ceramic uas twb muaj lawm uas tuaj yeem siv los ua cov ntaub ntawv hauv qab, Silicon Nitride ceramics muaj lub zog siab tshaj plaws, hnav tsis kam, thiab cov khoom zoo tshaj plaws ntawm cov khoom siv ceramic, thaum lawv coefficient ntawm thermal expansion yog qhov tsawg tshaj plaws. Aluminium Nitride ceramics muaj cov thermal conductivity, zoo thermal poob siab tsis kam, thiab tseem muaj cov khoom siv zoo ntawm qhov kub thiab txias. Nws tuaj yeem hais tau tias, los ntawm qhov pom ntawm kev ua tau zoo, Aluminium Nitride thiab Silicon Nitride tam sim no yog qhov tsim nyog tshaj plaws rau kev siv hauv cov khoom siv hluav taws xob ntim khoom, tab sis lawv kuj muaj ib qho teeb meem: lawv cov nqi siab.
3. Kev siv rau cov khoom siv hluav taws xob
Nyob rau hauv cov nqe lus ntawm photoelectric conversion efficiency, aluminium nitride (AlN) muaj ib tug ncaj bandgap semiconductor band siab tshaj plaws ntawm 6.2 eV, uas yog siab tshaj qhov indirect bandgap semiconductor. AlN, raws li ib qho tseem ceeb xiav thiab ultraviolet lub teeb-emitting khoom, yog siv nyob rau hauv ultraviolet thiab sib sib zog nqus ultraviolet lub teeb-emitting diodes, ultraviolet laser diodes, ultraviolet detectors, thiab lwm yam. AlN thiab III-group nitrides zoo li GaN thiab InN kuj tsim ib tug nruam khoom. kev daws teeb meem, thiab qhov sib txawv ntawm nws cov ternary lossis quaternary alloy tuaj yeem hloov kho tsis tu ncua los ntawm qhov pom band mus rau qhov sib sib zog nqus ultraviolet band, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv teeb pom kev zoo.
4. Daim ntawv thov rau cov khoom siv substrate
AlN Crystal yog qhov zoo tshaj plaws substrate rau GaN, AlGaN, thiab AlN epitaxial cov ntaub ntawv. Piv nrog rau sapphire lossis SiC substrates, AlN thiab GaN muaj qhov sib xyaw ua ke zoo dua thermal thiab tshuaj lom neeg sib xyaw, thiab kev ntxhov siab ntawm substrate thiab epitaxial txheej yog me dua. Yog li, AlN crystals li GaN epitaxial substrates tuaj yeem txo qhov tsis xws luag hauv cov cuab yeej thiab txhim kho nws cov kev ua tau zoo, uas muaj kev cia siab zoo heev ntawm daim ntawv thov hauv kev npaj cov kub kub, siab zaus, thiab cov khoom siv hluav taws xob muaj zog. Tsis tas li ntawd, siv AlN crystals raws li AlGaN epitaxial cov ntaub ntawv substrate nrog siab aluminium (Al) Cheebtsam kuj tuaj yeem txo qhov tsis xws luag hauv txheej txheej nitride epitaxial thiab txhim kho kev ua tau zoo thiab lub neej ntawm nitride semiconductor li. Raws li AlGaN, qhov zoo tshaj plaws hnub tsis pom kev ntes tau ua tiav tiav.
5. Daim ntawv thov rau ceramics thiab cov ntaub ntawv refractory
Aluminium Nitride tuaj yeem siv rau hauv cov txheej txheem ceramic sintering; Npaj Aluminium Nitride ceramics tsis tau tsuas yog cov khoom zoo dua qub thiab lub zog flexural dua li Al2O3 thiab BeO ceramics, tab sis kuj muaj zog dua thiab corrosion kuj.Siv cov cua sov thiab yaig kuj ntawm AlN ceramics, lawv tuaj yeem siv los ua crucibles, Al evaporation tais diav, thiab lwm yam kub-resistant corrosion-resistant qhov chaw. Tsis tas li ntawd, ntshiab AlN ceramics rau cov xim tsis muaj pob tshab, nrog cov khoom siv kho qhov muag zoo, tuaj yeem siv los ua pob tshab ceramics rau cov khoom siv kho qhov muag hluav taws xob thiab cov khoom siv rau cov qhov rais kub kub infrared thiab rectifier tshav kub-resistant txheej.
