(Cadaadis kulul AlNWaxaa soo saarayWintrustek)
Aluminium nitride (AIN) waxay caan ku tahay kuleylkeeda wanaagsan iyo tayada dahaarka korantada ee gaarka ah. Waa walax dhoobo ah oo caadi ah oo loo isticmaalo qalab koronto oo kala duwan. Aluminium nitride ceramics-ku waxay adkaysi u leeyihiin biraha dhalaalay, oo ay ku jiraan naxaasta, lithium, iyo aluminium, marka lagu daro balaadhinta kulaylka iyo sifadooda korantada. Aluminium nitridewaa shay faa'iido leh oo ku jira codsiyada warshadaha kala duwan taas oo ay ugu wacan tahay sifooyinkeeda kiimikaad iyo jidheed.
Si kastaba ha ahaatee, wax soo saarka, nitride aluminium ayaa ugu horrayn u kala qaybsan laba nooc oo ku salaysan habka sintering: prnitride aluminium sinteed aan hubin iyoaluminium nitride kuleyl lagu riixo. Tilmaamaha iyo adeegsiga labadan qaybood ayaa aad u kala duwan.
Aluminium nitride aan cadaadis lahaynisku daraa budada nitride aluminium saafi ah oo nadiif ah oo leh qadar yar oo ah gargaarka sintering (sida Y2O3), qaabaynta isku dhafka qaabka la rabo (tusaale, adigoo riixaya qalalan ama cadaadis isostatic), ka dibna ku dheji heerkul sare (1800 ° C ilaa 2000 ° C) oo hoos yimaada jawi badbaado ah (nitrogen). Nidaamkani wuxuu ku tiirsan yahay falcelinta u dhaxaysa gargaarka sintering iyo alumina ee jooga dusha sare ee qaybaha AlN, samaynta weji dareere ah oo kor u qaadaya dib u habeynta iyo cufnaanta qaybaha.
Astaamaha:
Qiimaha hoose: shuruudaha qalabku waa kuwo fudud, taas oo ka dhigaysa mid ku habboon wax soo saarka ballaaran ee ballaaran.
Qaababka isku dhafan: waxay soo saari kartaa qaybo kala duwan oo qaab aan caadi ahayn iyo taarikada khafiifka ah (sida substrates dhoobada).
Waxqabadka: inkasta oo ay dabooli karto inta badan baahida warshadaha, sababtoo ah la'aanta cadaadiska dibadda, daloolada yaryar ayaa si fudud ugu jira walxaha, cufnaanta badanaa waxay u dhaxaysaa 97% iyo 99%.
Codsiyada ugu muhiimsan:
Qaybaha baakadaha semiconductor (sida LED iyo substrates moduleka korantada)
Weelka kulaylka iyo gaasaska dahaadhka ah
Qaybaha qalabka daxalka u adkaysta iyo kulaylka u adkaysta
Aluminium nitride kuleyl lagu riixaywaxaa lagu soo saaraa hab gaar ah oo loo yaqaan cadaadis kulul. Inta lagu jiro sintering heerkulka sare, cadaadis sare unidirectional tobanaan ama xataa boqolaal megapascals ayaa lagu dabaqaa alaabta. Saamayntan isdhexgalka ee heerkulka sare iyo cadaadiska sare ayaa fure u ah gaaritaanka waxqabadkiisa gaarka ah.
Astaamaha:
Cufnaanta aadka u sarreysa: cadaadisku wuxuu ka saaraa daloolada u dhexeeya qaybaha, taasoo keentay cufnaanta u dhowaan karta qiimaha aragtida (99%).
Sifooyin farsamo oo aad u wanaagsan: marka loo eego sida caadiga ah ee AlN, kulaylka la cadaadiyo AlN ayaa leh xoog dabacsanaan iyo qallafsanaan sare leh.
Daawaynta kulaylka aad u fiican: sababtoo ah porosity-ka aadka u hooseeya, fidinta phonon waa la dhimay, iyo kuleylkeeda kulaylka badanaa waa mid deggan oo u dhow xadka sare.
Xaddidaad: kharash sare, hufnaan wax soo saar hooseeya, iyo sida caadiga ah kaliya qaababka joomatari ee fudud sida saxannada ama blocks ayaa la farsamayn karaa.
Codsiyada ugu muhiimsan (shuruudaha gaarka ah ee dhamaadka-sare):
Kala-baxa kulaylka iyo baakadaha laydhka awoodda sare leh
Jiilka xiga ee cufnaanta raadiyaha cufnaanta sare / aaladaha makarawga
Diidmada kulaylka ee nidaamyada elektiroonigga ah ee la isku halleyn karo aadka u sarreeya ee garoonka hawada sare
Qalabka cilmi baadhista sayniska ama qaybaha baadhista bar-tilmaameedka ee ku jira xaalado aad u daran
Sidee tahay inaad doorato?
Dooronitride aluminium aan cadaadis lahaynhaddii: aad la shaqaynayso looxyada wareegga elektiroonigga ah (PCBs), weelka kulaylka LED, ama qaybaha dahaarka warshadaha fudud. Aluminium nitride aan cadaadis lahayn ayaa ah ikhtiyaarka ugu kharashka badan uguna qaan-gaadhka ah.
Dooroaluminium nitride kuleyl lagu riixohaddii: Deegaanka codsigaagu uu yahay mid aad u baahan, sida chucks electrostatic (ESCs) ee qalabka etching semiconductor, saldhigyada laser-waxqabadka sare, ama qaybaha qaabdhismeedka saxda ah ee u baahan inay u adkeystaan culeyska farsamada sare. Cufnaanta iyo faa'iidooyinka xoogga leh ee nitride aluminiumka kulul ee la riixay ayaa ah kuwo aan la bedeli karin xaaladahan.
