I-aluminiyam i-nitride ceramic luhlobo lwemathiriyeli ye-ceramic kunye ne-aluminiyam nitride (AIN) njengenqanaba lekristale eliphambili. Ukufakela isekethe yentsimbi kwi-aluminiyam nitride ceramic substrate yi-aluminiyam nitride ceramic substrate.

1. I-Aluminiyam i-nitride ceramic yi-ceramic kunye ne-aluminiyam nitride (AIN) njengenqanaba eliphambili le-crystalline.

2. I-Ain crystal ithatha (i-ain4) i-tetrahedron njengeyunithi yolwakhiwo, ikhompawundi ye-covalent bond, inesakhiwo se-wurtzite kwaye yeyesistim ye-hexagonal.

3. Ukwakheka kwemichiza ai65 81%, N34. I-19%, ubunzima obuthile obuyi-3.261g / cm3, obumhlophe okanye obungwevu obumhlophe, ikristale enye engenambala kwaye iyabonakala, i-sublimation kunye neqondo lokushisa lokubola phantsi koxinzelelo oluqhelekileyo yi-2450 ℃.

4. I-Aluminiyamu ye-nitride ceramic yinto ephezulu yokushisa ukushisa kunye ne-coefficient yokwandiswa kwe-thermal (4.0-6.0) x10 (- 6) / ℃.

5. I-Polycrystalline ain ine-thermal conductivity ye-260W / (mk), ephindwe ngamaxesha angama-5-8 ngaphezu kwe-alumina, ngoko inokumelana nokutshatyalaliswa kobushushu kwaye inokumelana nobushushu obuphezulu be-2200 ℃.

6. Iiseramikhi ze-aluminiyam ze-nitride zinokumelana nokugqwesa okugqwesileyo.

Ibhodi yesekethe yeCeramic ineepropati ezilungileyo eziphezulu-frequency kunye nombane, kwaye ineepropati ezingenayo i-organic substrates, ezifana ne-conductivity ephezulu ye-thermal, uzinzo oluhle kakhulu lweekhemikhali kunye nokuzinza kwe-thermal. Yimpahla yokupakisha efanelekileyo kwisizukulwana esitsha seesekethe ezinkulu ezidibeneyo kunye neemodyuli zamandla e-elektroniki.

Izixhobo ze-Semiconductor ezifunwa ngamaziko okuhlala kunye nezixhobo zoshishino ziphuhliswa ngokukhawuleza, ngokusetyenziswa kwamandla aphezulu, ukuhlanganiswa okuphezulu kunye ne-modularization, ukhuseleko oluphezulu kunye nokusebenza okubucayi. Ngoko ke, ukulungiswa kwezinto eziphezulu ze-thermal conductivity kuseyingxaki engxamisekileyo ukuba isonjululwe ngoku. I-ceramics esekelwe kwi-aluminium nitride ineepropati ezifanelekileyo kakhulu ezifanelekileyo. Kwaye emva kovavanyo olwahlukeneyo, luye lwabonakala ngokuthe ngcembe kumbono wabantu, kwaye indawo enkulu yesicelo yimveliso yamandla aphezulu e-LED.
Njengomkhondo ophambili wokuhamba kobushushu, ibhodi ye-aluminium nitride ye-ceramic ye-ceramic ibalulekile kwi-package application ye-LED enamandla amakhulu. Idlala indima ebaluleke kakhulu ekuphuculeni ukusebenza kakuhle kokutshatyalaliswa kobushushu, ukunciphisa ukushisa kwe-junction kunye nokuphucula ukuthembeka kunye nobomi benkonzo yesixhobo.

Ibhodi yesekethe yokupholisa ye-LED yahlulwe kakhulu ibe: ibhodi yesekethe ye-LED kunye nebhodi yesekethe yenkqubo. Ibhodi yesekethe ye-LED isetyenziswa ikakhulu njengomthombo wamandla obushushu angaphandle phakathi kwebhodi ye-LED kunye nebhodi yesekethe yenkqubo, edityaniswe ne-LED ngenkqubo yokuzoba ngocingo, i-eutectic okanye i-cladding.

Ngophuhliso lwe-LED enamandla amakhulu, ibhodi yesekethe ye-ceramic yeyona bhodi yesekethe ephambili esekwe kuqwalaselo lokutshatyalaliswa kobushushu: kukho iindlela ezintathu zokulungiselela zemveli zesekethe yamandla aphezulu:

1. Ibhodi yeceramic eshinyeneyo yefilimu

2. Ubushushu obuphantsi co budunyiswe iikeramikhi ezininzi

3. Ifilim ebhityileyo yebhodi yesekethe yeceramic

Ngokusekwe kwimowudi yendibaniselwano yeenkozo ze-LED kunye nebhodi yesekethe ye-ceramic: ucingo lwegolide, kodwa ukudityaniswa kocingo lwegolide kunciphisa ukusebenza kakuhle kokutshatyalaliswa kobushushu ecaleni koqhagamshelwano lwe-electrode, ngoko ke idibana nebhotile yokuchitha ubushushu.

I-Aluminiyam nitride ceramic substrate iya kuthatha indawo yebhodi ye-aluminiyam yesekethe kwaye ibe yinkosi ephezulu yamandla amakhulu emakethe ye-chip ye-LED kwixesha elizayo.
