Aluminium nitride ceramic substrate yog lub substrate ua los ntawm txhuas nitride ceramic ua cov khoom tseem ceeb.Raws li ib yam tshiab ntawm ceramic substrate, nws muaj cov yam ntxwv ntawm high thermal conductivity, zoo mechanical zog, corrosion kuj, zoo heev hluav taws xob zog, weldability thiab thiaj li nyob.Nws yog ib qho zoo tagnrho tshav kub dissipation substrate thiab ntim khoom rau loj-scale integrated circuits.Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm lub ntiaj teb cov ntaub ntawv xov xwm kev lag luam, kev ua lag luam yuav tsum tau ua rau kev ua tau zoo ntawm ceramic substrates txuas ntxiv txhim kho.Nrog nws cov yam ntxwv zoo heev, aluminium nitride ceramic substrates txuas ntxiv nthuav lawv qhov kev thov.
Raws li cov ntaub ntawv tseem ceeb, lub ntiaj teb kev lag luam tus nqi ntawm txhuas nitride (AlN) ceramic substrates tau txog 340 lab yuan hauv 2019, thiab nws xav tias yuav loj hlob mus rau 620 lab yuan hauv 2026, nrog rau kev loj hlob txhua xyoo ntawm 8.4%.
Cov yam ntxwv tseem ceeb ntawm aluminium nitride ceramic substrate:
(1) High thermal conductivity, ntau tshaj 5 npaug ntawm alumina ceramics;
(2) Qhov qis thermal expansion coefficient (4.5-10-6 / ℃) phim cov khoom siv semiconductor silicon (3.5-4.0-10-6 / ℃);
(3) Tsawg dielectric tsis tu ncua
(4) Zoo heev insulating zog
(5) Cov khoom siv zoo heev, lub zog flexural yog siab dua li ntawm Al2O3 thiab BeO ceramics, thiab tuaj yeem sintered ntawm ib txwm muaj siab;
(6) Thaum tshav kub kub tsis kam thiab corrosion kuj ntawm molten hlau
