Fraunhofer IISB (Lub Koom Haum rau Kev Sib Koom Tes thiab Kev Siv Tshuab) hauv Erlangen thiab lub tuam txhab tsim lub tshuab microwave & radio frequency plasma system PVA TePla AG hauv Wettenberg tab tom sib sau ua ke lawv cov kev txawj ntse hauv Chav Kuaj Sib Koom Tes rau kev tsim cov siv lead ua los ntawm txhuas nitride (AlN).
Ua thawj zaug hauv Tebchaws Europe, qhov kev koom tes no ua rau muaj kev txhawb nqa los ntawm kev lag luam los tsim cov khoom me me ntawm monocrystalline AlN substrates nrog lub cheeb ntawm 2-nti rau R&D lub hom phiaj. Qhov no txhim kho qhov muaj AlN substrates hauv Tebchaws Europe, uas ua rau kev txhim kho ntawm AlN-based cov khoom siv thiab cov kab ke thiab lawv hloov mus rau kev siv hauv kev lag luam sai dua.
Aluminium nitride yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau tiam tom ntej ntawm cov khoom siv hluav taws xob ua tau zoo. Ua ib qho ultrawide-bandgap (UWBG) semiconductor, AlN qhib cov cib fim tshiab hauv photonics, fais fab hluav taws xob, hluav taws xob zaus siab, thiab hluav taws xob ua haujlwm hauv qab qhov xwm txheej hnyav. Txog niaj hnub no, qhov tsis txaus ntawm cov khoom siv AlN zoo, thaj chaw loj thiab pheej yig tau ua rau kev tsim cov kab ke hluav taws xob raws li AlN qeeb.
"Nrog rau Lub Chaw Kuaj Sib Koom Tes, peb tab tom tsim lub hauv paus kom ntseeg tau tias muaj cov khoom siv AlN los ntawm Tebchaws Europe, yog li qhib kev cia siab tshiab rau tiam tom ntej ntawm cov khoom siv AlN ua tau zoo," Dr Sven Besendörfer, tus thawj coj pab pawg rau cov ntaub ntawv nitride thiab lub luag haujlwm rau kev tsim khoom AlN ntawm Fraunhofer IISB hais. "Ua ke nrog PVA TePla, peb tab tom pab txhawb peb cov kev txawj ntse hauv kev loj hlob ntawm cov siv lead ua lag luam, yog li tsim cov kev xav tau ua ntej rau kev hloov mus rau cov ntawv thov pob zeb."
Cov cuab yeej siv tshuab uas tau lees paub ua tiav raws li kev paub txog cov txheej txheem tshwj xeeb
Hauv chav kuaj ua ke, Fraunhofer IISB siv nws cov txheej txheem PVT (kev thauj mus los ntawm lub cev) los tsim cov pob zeb AlN loj 2-nti. Hauv cov txheej txheem no, hmoov AlN raug ua pa hauv lub crucible ntawm qhov kub siab dua 2000 ° C thiab tso rau ntawm cov pob zeb noob. PVA TePla muab cov txheej txheem PVT rau lub hom phiaj no, uas twb siv thoob ntiaj teb rau cov pob zeb silicon carbide (SiC) loj 8-nti thiab tam sim no tau hloov kho tshwj xeeb rau kev loj hlob ntawm cov pob zeb AlN loj 2-nti.
Vim yog Fraunhofer IISB txoj kev txawj ntse ua haujlwm, pab pawg PVA TePla tau sai sai tsim cov AlN crystals zoo sib xws hauv nws cov chaw. Lub Chaw Kuaj Mob Sib Koom Tes tsom mus rau kev tsim cov khoom me me ruaj khov ntawm 2-nti AlN crystals. Kev tsim khoom tam sim no tau nce maj mam kom ua kom zoo dua qub rau kev ruaj khov ntawm cov txheej txheem, kev rov ua dua tshiab, cov txiaj ntsig thiab cov qauv nqi.
"Nrog rau aluminium nitride, peb tab tom ua kom cov thev naus laus zis tom ntej tom qab SiC," Dr Jan Pfeiffer, tus lwm thawj coj ntawm R&D ntawm PVA TePla hais. "Los ntawm Joint Lab, peb tuaj yeem sib txuas peb cov khoom siv txawj ntse nrog cov txheej txheem paub ntawm Fraunhofer IISB, ua rau peb muaj peev xwm muab cov kev daws teeb meem rau peb cov neeg siv khoom thoob ntiaj teb thaum ntxov," nws hais ntxiv. "Peb lub hom phiaj sib koom yog txhawb kev txhim kho kev lag luam hauv AlN sector los ntawm cov khoom siv tsim nyog thiab txhawb nqa cov tuam txhab uas tab tom nrhiav kev nkag mus rau hauv daim teb no ua cov neeg koom tes thev naus laus zis nrog cov khoom siv zoo thiab kev txawj ntse ua haujlwm sib xws."
Kev txhawb nqa European kev siv tshuab los ntawm kev nthuav dav kev lag luam
Cov AlN crystals uas tsim tawm hauv Joint Lab raug ua tiav ntxiv ntawm Fraunhofer IISB mus rau hauv cov khoom siv AlN uas npaj txhij thiab, los ntawm Erlangen-based research & product development firm LZE GmbH, tshwj xeeb tshaj yog hloov mus rau hauv kev txhim kho kev lag luam thiab cov txheej txheem scaling. "Rau Tebchaws Europe lub semiconductor sovereignty, nws yog ib qho tseem ceeb uas cov ntaub ntawv tseem ceeb tshiab tsis yog tsuas yog tsim tab sis kuj hloov mus rau hauv cov ntawv thov kev lag luam thiab kev tsim nqi scalable," LZE tus thawj coj Dr Christian Forster hais. "Nrog nws lub khw rau cov thev naus laus zis tshiab, LZE GmbH muab cov tuam txhab thiab cov tsev kawm ntawv tshawb fawb nrog kev nkag mus rau AlN substrates thoob ntiaj teb. Ua li no, peb pab xyuas kom meej tias cov ntawv thov cog lus rau cov lag luam kev lag luam loj tau coj mus rau kev lag luam sai dua."
