Aluminium Nitride Ceramic: Meesha ugu Sarreysa ee Heerarka Sare ee Kuleylka Korantada Farsamada Caalamiga ah

Xilli uu maamulka kulaylku qeexayo horumarka tignoolajiyada, aluminium nitride ceramic (ALN ceramic) Waxa uu kor u kacay sidii geesiga aan la heesin, oo awood u leh horumarka kaabayasha 5G ilaa awoodda baabuurta korontada. Iyada oo kulaylka kuleylku uu la tartamayo biraha iyo dahaarka korantada oo ka baxsan ceramics-ka caadiga ah, maaddadan hadda waxay taageertaa codsiyada muhimka ah halka guul-darradu aanay ahayn ikhtiyaar.

Aluminium Nitride

Tartanka garoonka aerospace-ka ee loogu talagalay qaybaha fudud ee la isku halleyn karo ayaa ka dhigay substrates nitride aluminium isla markiiba iftiinka. Taargooyinkan aadka u-flat ah, kulaylka la xoojiyey waxay u shaqeeyaan sidii aasaaska qaybaha tamarta dayax-gacmeedka, iyagoo si guul leh u baabi'iya kulaylka agagaaraha wareegyada ee bilaa ogsajiinta. Daraasad 2024 NASA ah ayaa xaqiijisay in substrate-yada ALN ay kor u qaadaan cimriga kaadhka wareegga 300% marka la barbar dhigo xulashooyinka alumina, si toos ah u saameeya qiimaha satalaytka.

Guryaha aluminium nitride waxay aad uga fog yihiin awoodda kulaylka. Isku dhafka gaarka ah ee firfircoonida kiimikada iyo qallafsanaanta farsamada ayaa ka dhigaysa mid aan lagama maarmaan u ah maaraynta waferka yar yar. Aasaasayaasha hormoodka ah hadda waxay si gaar ah u isticmaalaan waferrada nitride aluminium wax soo saarka silikoon carbide chip, maadaama ay u adkeysanayaan heerkulka habka 1,800C iyaga oo aan wasakheynin lakabyada epitaxial ee xasaasiga ah. Isbeddelkan ayaa hoos u dhigay heerka cilladda chip 42% Q1 2024 oo keliya.  

Baabuur-sameeyayaasha la dagaallamaya xaddidaadaha kala duwan ee EV waxay u jeesteen xaashida nitride aluminium si looga hortago kulaylka batteriga. Caqabadahan millimeter-ka khafiifka ah, ee isku dhafan ee u dhexeeya unugyada lithium-ion, waxay ku dhaqmaan kulayl 15x ka dhaqso badan polymers-ka caadiga ah iyadoo la ilaalinayo awoodda dielectric. Warbixinta badbaadada batteriga ee Q2 ee Tesla ayaa lagu qiimeeyay xaashida ALN 67% hoos u dhac ku yimid darnaanta shilalka kulaylka ee 2 milyan oo baabuur.  

Kobcinta tamarta dib loo cusboonaysiin karo ayaa xoojisay baahida loo qabo taarikada nitride aluminium ee rogo-rogayaasha tamarta sare leh. Soosaarayaasha marawaxadaha dabaysha ayaa hadda ku dhejiyay taarikadan cutubyada korantada si ay u xakameeyaan 10kV+ culeyska, iyaga oo gaaraya 98.5% waxtarka beddelka tamarta - 5% ayaa ka booday naqshadihii hore. Hal-abuurkani wuxuu si toos ah wax uga qabanayaa caqabadaha xasilloonida ee ka jira gobollada ku tiirsan qoraxda/dabaysha.  

Khadadkayaga wax soo saarka ee ISO-shahaadeeyay ayaa hadda bixiya qaybaha dhoobada ALN oo leh flatness-mikroroon-hoosaad, shuruud muhiim ah oo loogu talagalay kombuyuutarrada xisaabinta unugyada cryogenic. Sifaynta farsamooyinka gaaska cadaadiska gaaska, waxaan ka saarnay porosity ee wafers nitride aluminium, gaarnay joogtooyinka dielectric ee ka hooseeya 8.5 at 1MHz - bartilmaameed mar loo arkay inaan la heli karin polycrystalline ALN.  

Aluminium Nitride saxannada

Hal-abuurayaasha aaladaha caafimaadku waxay ka faa'iidaystaan ​​ku-qabsiga aluminium nitride ee dareemayaasha la rakiban karo. Tijaabooyinkii dhawaa waxay muujinayaan ALN ​​ceramik-ku-xidhan kormeerayaasha gulukoosta waxay ilaalinayaan saxnaanta 18+ bilood gudaha Vivo, iyagoo ka sarreeya tiirarka titanium-ka iyagoo iska caabiyay dareeraha jirka acidic. Horumarkan ayaa waxa uu dhimi karaa kharashaadka maaraynta xanuunka macaanka $12 bilyan sannadkii 2026.  

Dulqaadka 5G ee rabitaan la'aanta kulaylka ayaa dib u qaabeeyay wax soo saarka substrate-ka ALN. Nidaamkeena isku-dubbaridka isku-dhafan ee rukhsadda leh ayaa u oggolaanaya ku-xidhka korantada tungsten gudaha xaashida nitride aluminium, taasoo awood u siinaysa modules-koronto 3D oo haysta 60% boos ka yar. Shirkadaha waaweyn ee isgaadhsiinta ayaa ka warbixiya 35°C heerkulka saldhiga ayaa hoos u dhacay iyadoo la isticmaalayo qaybahan, taasoo kordhinaysa cimriga qalabka 8 sano.

Dagaallada jilibka-siyaasadeed waxay sameeyeen silsiladaha sahayda wafer ee aluminium nitride hanti istiraatiiji ah. Waxaanu kala duwanaynay ka-soo-saarka alaabta ceeriin ee saddexda qaaradood, anagoo hubinayna saadka ytria ee xasiloon ee agabka qallafsan inkasta oo ay naadir tahay isbeddelka suuqa dhulka. Warshadeena Vietnam waxay hadda soo saartaa taarikada ALN oo leh 99.8% nadiif ah, oo hareer maray caqabadaha ganacsiga ee saameeya dhoobada Shiinaha laga keeno.  

Joogteynta ayaa kaxeysa hal-abuurnimadayada nitride aluminium. Nidaam shiidid xiran oo shiidid ah ayaa soo kabanaya 92% qashinka dhoobada ALN, kaas oo aan dib ugu celino buuxinta kulaylka leh ee xabagta EV. Habkan wareegtada ah ayaa hoos u dhigay CO₂ wax soo saarka 18,000 tan sanadkiiba iyada oo kharashka 14% ka hooseysa celceliska warshadaha.  

Sida Warshadaha 4.0 ay u dedejiso, guryaha nitride aluminium ayaa dib loo qeexay. Kooxdayada R&D waxay dhowaan soo saareen go'yaal ALN ah oo leh microchannel-ka laser-ku-qoday oo loogu talagalay qaboojinta laba-waji ee serferrada AI. Tijaabooyin hore waxay muujinayaan 500W/cm² awoodda qulqulka kulaylka—oo saddex jibaaraya xadka qaboojinta dareeraha hadda — taasoo ka dhigaysa isticmaalka xarunta xogta isticmaalka biyaha.  

Soosaarayaasha u socda RoHS iyo u hoggaansanaanta REACH, aluminium nitride substrates waxay bixiyaan beddelaad bir-la'aan ah oo culus oo ah ceramics beryllia. Wafersyadayada ALN ee REACH-ku-shahaadad siiyay waxay baabi'iyaan khataraha siigada mishiinka ee kansarka iyadoo la barbardhigayo waxqabadka kulaylka ee Beryllia-arrin muhiim ah oo ah 300% baahida EU ee kor u kaca tan iyo 2023.  

Qaybta difaaca jinsigeeda hypersonic waxay ku tiirsan tahay ALN radomes dhoobada. Taarikadayada nitride aluminium ee aerospace-ka ah waxay ilaalinayaan daahfurnaanta calaamadaha ka sarreeya xawaaraha Mach 5, iyagoo xallinaya arrimaha madaw ee balaasmaha ee dhibay agabka dhaxalka ah. Tijaabadii dhawayd ee Lockheed Martin waxa lagu tiriyaa ALN radomes 100% haynta telemetry inta lagu jiro dhaqdhaqaaqyada muhiimka ah.  

Isbeddelka qiimaha alaabta ceeriin ee nitride aluminium ayaa weli ah caqabad. Nidaamkeena wax iibsiga ee ay wado AI wuxuu saadaaliyaa isbeddellada qiimaha aluminium iyo horudhacyada nitrogen, taasoo awood u siinaya wax iibsiga badan inta lagu jiro suuqa. Macaamiishu waxay ka faa'iidaystaan ​​15-22% kaydinta kharashka iyada oo loo marayo qaabkayaga qiimaha firfircoon iyada oo aan la hureynin u hoggaansanaanta EN 60672-2.

Laga soo bilaabo aluminium nitride wafer-enabled terahertz chips ilaa ALN darbiyada isku dhafka dhoobada leh, qoyskani wuxuu sii wadaa burburinta saqafka waxqabadka. Maaddaama warshadaha caalamiga ahi ay wajahayaan dalabaadka kuleyliyaha iyo xakamaynta ee sii kordhaya, xalalka nitride aluminium ma aha oo kaliya faa'iido - waxay noqonayaan baahiyo jira.
