Chav Kawm Me ntawm Aluminium Nitride Substrate

Aluminium nitride substrate (AIN substrate) yog cov khoom siv semiconductor nrog cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb. Nws yog dav siv hauv cov khoom siv hluav taws xob, cov khoom siv optoelectronic, thermal tswj thiab lwm yam haujlwm. Aluminium nitride substrate muaj siab thermal conductivity. Lub thermal conductivity ntawm AIN substrate yog siab heev, txog 320W / m·K, ze rau BeO thiab SiC, thiab ntau tshaj 5 npaug ntawm Al2O3. Qhov no ua rau AIN yog cov khoom siv zoo tshaj plaws hauv kev tswj xyuas thermal, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv hluav taws xob muaj zog, uas tuaj yeem txo cov cuab yeej kub thiab txhim kho kev ua haujlwm thiab kev ntseeg siab. Aluminium nitride substrate muaj hluav taws xob rwb thaiv tsev. Txij li thaum AIN muaj qhov sib txawv loj ntawm 6.2eV, nws muaj hluav taws xob rwb thaiv tsev siab. Yog li ntawd, aluminium nitride substrate tuaj yeem tiv thaiv qhov ntws ntawm qhov tam sim no hauv qhov kub thiab txias ib puag ncig, tiv thaiv kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob. Aluminium nitride substrate muaj txhua yam khoom. AIN muaj siab hardness thiab tensile zog thiab muaj zoo txhua yam khoom. Yog li ntawd, aluminium nitride substrate tsis yooj yim los tsim cov kab nrib pleb thiab qhov tsis xws luag thaum lub sij hawm npaj, uas txhim kho kev ntseeg tau thiab lub neej ntawm cov cuab yeej. Aluminium nitride substrate yog cov khoom siv kub-resistant. Lub sublimation decomposition kub ntawm AIN siv lead ua nyob rau hauv ib txwm siab yog 2450 degree, uas yog ib tug high-kub kub-resistant khoom. Aluminium nitride substrate yog resistant rau tshuaj corrosion. AIN muaj ib daim ntawv thov tshwj xeeb ntawm txhuas nitride substrate uas tsis corroded los ntawm txhuas kua thiab lwm yam hlau molten thiab gallium arsenide. Vim nws cov thermal conductivity, tsis tshua muaj expansion coefficient, siab zog, siab kub tsis kam, tshuaj corrosion kuj, siab resistivity, thiab tsis tshua muaj dielectric poob, AIN substrate tau dhau los ua ib qho zoo tagnrho loj-scale integrated circuit heat dissipation substrate thiab ntim khoom.
AIN muaj siab hardness, tshaj ib txwm alumina, thiab yog ib yam tshiab ntawm hnav-resistant ceramic khoom. AIN zaj duab xis muaj cov khoom siv kho qhov muag zoo thiab tuaj yeem siv los tsim cov khoom siv piezoelectric siab, ultra-loj-scale integrated circuit substrates, thiab lwm yam. 300nm, suav nrog UVC lub teeb emitting diodes (UVC LEDs) thiab laser diodes. AIN substrates qhia tau hais tias muaj peev xwm ua lag luam zoo vim lawv qhov kev ua tau zoo hauv cov khoom siv hluav taws xob hluav taws xob thiab xov tooj cua zaus (RF), tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov nyob rau hauv huab cua.
Peb yog cov chaw tsim khoom, chaw tsim khoom thiab chaw muag khoom tshwj xeeb hauv ceramics hauv Suav teb. Cov ceramics peb tsim yog: Silicon carbide, aluminium nitride, alumina, ultrapure alumina, yttria, zirconia, High-purity thiab high-performance boron nitride ceramics zirconia toughened alumina (ZTA), txhuas toughened zirconia (ATZ), silicon nitride thiab lwm yam reinforced ceramics, composite ceramics thiab siab ceramics.
