Le nitrure d'aluminium poss\u00e8de une excellente conductivit\u00e9 thermique (5 \u00e0 10 fois celle des c\u00e9ramiques d'alumine), une faible constante di\u00e9lectrique et une faible perte di\u00e9lectrique, des performances d'isolation fiables, d'excellentes propri\u00e9t\u00e9s m\u00e9caniques, un caract\u00e8re non toxique, une r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, une r\u00e9sistance \u00e0 la corrosion chimique et un coefficient de dilatation thermique similaire \u00e0 celui du silicium. La c\u00e9ramique de nitrure d'aluminium est largement utilis\u00e9e dans les appareils de communication, les LED \u00e0 haute luminosit\u00e9, les appareils \u00e9lectroniques de puissance et d'autres industries. C'est un substrat de dissipation thermique id\u00e9al et un mat\u00e9riau d'emballage pour les circuits int\u00e9gr\u00e9s \u00e0 grande \u00e9chelle.

Substrats en nitrure d'aluminium<\/a>\u00a0est une nouvelle g\u00e9n\u00e9ration de substrat c\u00e9ramique \u00e0 haute performance. Il poss\u00e8de une conductivit\u00e9 thermique \u00e9lev\u00e9e (la valeur th\u00e9orique est de 319w \/ m.k, et la conductivit\u00e9 thermique est sup\u00e9rieure \u00e0 140W \/ m.k), une faible constante di\u00e9lectrique (8,8) et une perte di\u00e9lectrique (~ 4) \u00d7 104) et le coefficient de dilatation thermique (4.4 \u00d7 10-4 \/ \u2103), composition chimique Al 65.81%, N 34.19%, densit\u00e9 3.261g\/cm3, blanc ou blanc gris, monocristal incolore et transparent, temp\u00e9rature de sublimation et de d\u00e9composition des substrats de nitrure d'aluminium est de 2450 \u2103 \u00e0 la pression atmosph\u00e9rique.<\/p>\n

La c\u00e9ramique de nitrure d'aluminium pr\u00e9sente une conductivit\u00e9 thermique \u00e9lev\u00e9e, de bonnes propri\u00e9t\u00e9s \u00e9lectriques, un coefficient de dilatation thermique proche de celui de la puce de Si, une grande solidit\u00e9, une r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, une r\u00e9sistance \u00e0 la corrosion chimique, une grande r\u00e9sistivit\u00e9, une faible perte di\u00e9lectrique et une absence de toxicit\u00e9. Le nitrure d'aluminium est un mat\u00e9riau id\u00e9al pour remplacer les c\u00e9ramiques BeO et constitue un substrat de dissipation thermique et un mat\u00e9riau d'emballage id\u00e9al pour les circuits int\u00e9gr\u00e9s \u00e0 grande \u00e9chelle.<\/p>\n

Les substrats en nitrure d'aluminium sont principalement utilis\u00e9s comme substrats et mat\u00e9riaux d'emballage de haute performance dans les circuits hybrides \u00e0 haute densit\u00e9, les dispositifs de puissance \u00e0 micro-ondes, les dispositifs \u00e9lectroniques de puissance, les composants opto\u00e9lectroniques, la r\u00e9frig\u00e9ration des semi-conducteurs et d'autres produits. Il est largement utilis\u00e9 dans les dispositifs de communication, les LED \u00e0 haute luminosit\u00e9, les dispositifs \u00e9lectroniques de puissance et d'autres industries.<\/p>","protected":false},"excerpt":{"rendered":"
