Aluminium nitride ceramic waa nooc ka mid ah walxaha dhoobada leh oo leh aluminium nitride (AIN) oo ah wajiga ugu weyn ee crystal. Wareegga birta ah ee ku dhejinaya aluminium nitride substrate dhoobada waa aluminium nitride substrate dhoobada.

1. Aluminium nitride ceramic waa dhoobo leh nitride aluminium (AIN) oo ah wajiga ugu muhiimsan ee crystalline.

2. Ain crystal waxay u qaadataa (ain4) tetrahedron sidii unug dhismeed, isku xidhka dammaanadda, waxay leedahay qaab dhismeed wurtzite waxayna ka tirsan tahay nidaamka laba geesoodka.

3. Halabuurka Kiimikada ai65 81% ， N34. 19%, cufnaanta gaarka ah 3.261g / cm3, caddaan ama cawl cad, hal crystal aan midab lahayn oo hufan, sublimation iyo burburka heerkulka hoos cadaadiska caadiga ah waa 2450 ℃.

4. Aluminium nitride dhoobada waa walxo heerkul sare leh oo u adkaysta kulaylka oo leh iskudar balaadhinta kulaylka (4.0-6.0) x10 (- 6) / ℃.

5. Polycrystalline Ain waxa uu leeyahay kulaylka kuleylkiisu yahay 260W/(mk), kaas oo 5-8 jeer ka sarreeya kan aluminiumka ah, sidaa awgeed waxa uu leeyahay iska caabin shoog kulayleed oo wanaagsan, waxana uu u adkeysan karaa heer kulka sare ee 2200 ℃.

6. Aluminium nitride ceramics waxay leeyihiin iska caabin daxalka oo aad u fiican.

Gudida wareegga dhoobada waxay leedahay soo noqnoqosho wanaagsan oo koronto ah, waxayna leedahay sifooyin aan lahayn substrate-ka organic, sida kulaylka kuleylka sarreeya, xasilloonida kiimikaad ee heer sare ah iyo xasilloonida kulaylka. Waa baakad ku habboon jiilka cusub ee wareegyada isku dhafan ee baaxadda weyn iyo korantada korantada.

Qalabka semiconductor ee looga baahan yahay tas-hiilaadka nolosha iyo qalabka warshadaha ayaa si degdeg ah u kobcaya, oo leh isticmaalka awood sare, isdhexgalka heerka sare iyo qaabaynta, arrin badbaado oo sarreeya iyo hawlgal xasaasi ah. Sidaa darteed, diyaarinta qalabka korantada kulaylka sare ayaa weli ah dhibaato degdeg ah oo la xalliyo ilaa hadda. dhoobada ku salaysan nitride aluminium ayaa leh sifooyinka ugu haboon ee dhamaystiran. Iyo tijaabooyin kala duwan ka dib, waxay si tartiib tartiib ah u soo muuqatay aragtida dadka, iyo goobta ugu weyn ee codsiga waa alaabada LED-ka ee awoodda sare leh.
Sida dariiqa ugu muhiimsan ee socodka kulaylka, aluminium nitride dhoobada wareegga wareegga ayaa lagama maarmaan u ah codsiga baakadaha ee LED-ga awoodda sare leh. Waxay ka ciyaartaa door aad muhiim u ah hagaajinta waxtarka kuleylka kuleylka, yareynta heerkulka isgoysyada iyo hagaajinta kalsoonida iyo nolosha adeegga qalabka.

Ulaha wareegga qaboojinta LED wuxuu badiyaa u qaybsan yahay: looxa wareegga hadhuudhka LED iyo guddiga wareegga nidaamka. looxa wareegga hadhuudhka LED waxaa inta badan loo isticmaalaa sida dhexdhexaadka ah dhoofinta tamarta kulaylka u dhexeeya hadhuudhka LED iyo guddiga wareegga nidaamka, kaas oo lagu daray hadhuudh LED by habka sawirka silig, eutectic ama cladding.

Iyadoo horumarinta awoodda sare ee LED, guddiga wareegga dhoobada ayaa ah guddiga wareegga ugu weyn ee ku salaysan tixgelinta kulaylka: waxaa jira saddex hab oo diyaarin dhaqameed oo wareeg ah oo awood sare leh:

1. looxa dhoobada filimada qaro weyn

2. Heerkulka hoose co shiday ceramics multilayer

3. Gudida wareegga dhoobada ee filimka khafiifka ah

Iyada oo ku saleysan habka isku dhafka ah ee hadhuudhka LED iyo guddiga wareegga dhoobada: silig dahab ah, laakiin isku xirka fiilada dahabka ayaa xaddidaya waxtarka kuleylka kulaylka iyada oo la raacayo xiriirka korantada, sidaas darteed waxay la kulantaa dhalooyinka kuleylka kuleylka.

Aluminium nitride dhoobada dhoobada ayaa bedeli doonta guddiga wareegga aluminium waxayna noqon doontaa maamulaha awoodda sare ee suuqa chip-ka LED mustaqbalka.
