Kei te whakakotahi te kamupene Fraunhofer IISB (Institute for Integrated Systems and Device Technology) o Erlangen me te kamupene hanga pūnaha ngaruiti me te auau reo irirangi o Wettenberg, PVA TePla AG, i ō rāua tohungatanga ki roto i tētahi Taiwhanga Tahi mō te hanga tioata konumohe nitride (AlN).
Hei te tuatahi ki Ūropi, ka taea e tēnei hononga te hanga i ngā papa AlN monocrystalline iti-pūranga e tautokona ana e te ahumahi me te diameter o te 2-inihi mō ngā kaupapa R&D. Ka whakapai ake tēnei i te wātea o ngā papa AlN i Ūropi, ā, ka tere ake te whanaketanga o ngā taputapu me ngā pūnaha e hangai ana ki te AlN me tō rātou whakawhiti ki ngā tono ahumahi.
Ko te konukōre konukōre tetahi o ngā rauemi tino whai hua mō te whakatupuranga e whai ake nei o ngā hikohiko mahi-teitei. Hei haurua-ā-ira whānui-rahi (UWBG), ka whakatuwherahia e te AlN ngā huarahi hou ki te hangarau whakaahua, te hikohiko mana, te hikohiko auau-teitei, me ngā hikohiko e mahi ana i raro i ngā āhuatanga tino kino. Tae noa ki tēnei wā, ko te korenga o ngā papa AlN kounga-teitei, he nui te rohe, he iti te utu, kua aukati i te whanaketanga o ngā pūnaha hiko e hangai ana ki te AlN.
"Mā te Joint Lab, kei te whakatakoto mātou i te turanga hei whakarite i te tuku pono o ngā papa AlN mai i Ūropi, ā, mā reira ka whakatuwhera i ngā huarahi hou mō te whakatupuranga e whai ake nei o ngā taputapu AlN mahi-teitei," te kī a Tākuta Sven Besendörfer, te kaiārahi rōpū mō ngā rauemi nitride me te kawenga mō te whanaketanga rauemi AlN i Fraunhofer IISB. "I te taha o PVA TePla, kei te tuku mātou i ō mātou tohungatanga ki te tipu tioata ahumahi, ā, mā reira ka hangaia ngā whakaritenga mō te whakawhiti ki ngā tono raima."
Ka tutuki te hangarau taputapu kua whakamātauhia ki ngā mōhiotanga tukanga motuhake
I roto i te taiwhanga tahi, kei te whakamahi a Fraunhofer IISB i tana hangarau tukanga PVT (kawe kohu tinana) motuhake hei whakaputa i ngā tioata papatipu AlN 2-inihi. I roto i tēnei tukanga, ka mimitihia te paura AlN i roto i tētahi oko i ngā pāmahana neke atu i te 2000°C, ka whakatakotoria ki runga i tētahi tioata purapura. Ka whakaratohia e PVA TePla ngā pūnaha PVT mō tēnei kaupapa, kua whakamahia kētia puta noa i te ao mō ngā tioata silicon carbide (SiC) 8-inihi te whānui, ā, kua whakatikatikaina inaianei mō te tipu o ngā tioata AlN 2-inihi.
Nā te tohungatanga tukanga i kohaina mai e Fraunhofer IISB, i tere te kaha o te tīma PVA TePla ki te whakaputa tioata AlN o te kounga rite i roto i ōna ake whare. Ko te arotahi a te Joint Lab ki te whakaputa i ngā tioata AlN 2-inihi te rahi, he iti te rahi, he pumau. Kei te piki haere te whakaputa inaianei kia pai ake ai te pumau o te tukanga, te kaha ki te whakaputa anō, te hua me ngā hanganga utu.
"Mā te konupūmā konupūmā, kei te kaha mātou ki te hanga i te whakatupuranga hangarau e whai ake nei i muri i te SiC," te kī a Tākuta Jan Pfeiffer, te tumuaki tuarua o te R&D i PVA TePla. "Mā te Joint Lab, ka taea e mātou te whakakotahi tika i ō mātou pūkenga taputapu me te mōhiotanga tukanga o Fraunhofer IISB, ka taea ai e mātou te tuku otinga e aro ana ki te mākete ki ō mātou kiritaki o te ao i te wā tōmua," tāna tāpiri. "Ko tā mātou whāinga tahi ko te whakaoho i te whanaketanga mākete i roto i te rāngai AlN mā roto i ngā papa e tika ana, me te tautoko i ngā kamupene e titiro ana ki te uru atu ki tēnei mara hei hoa hangarau me ngā taputapu tika me te tohungatanga tukanga e rite ana."
Te whakapakari i te mana motuhake hangarau o Ūropi mā te tauine ahumahi
Ko ngā tioata AlN i hangaia i te Joint Lab ka tukatukahia anō i Fraunhofer IISB hei papa AlN epi-ready, ā, mā te kamupene rangahau me te whakawhanake hua o Erlangen, LZE GmbH, ka whakawhitia motuhaketia ki ngā tukanga whanaketanga ahumahi me te tauine. "Mō te mana motuhake o te semiconductor o Ūropi, he mea nui kia kaua e whakawhanakehia noa ngā rauemi matua hou engari kia tere hoki te whakawhiti ki ngā tono ahumahi me te waihanga uara tauine," te kī a te kaiwhakahaere matua o LZE, a Tākuta Christian Forster. "Me tana mākete mō ngā hangarau hou, ka whakaratohia e LZE GmbH ki ngā kamupene me ngā umanga rangahau he urunga motuhake me te tuwhera o te ao ki ngā papa AlN. Mā tēnei, ka āwhina mātou ki te whakarite kia tere ake te kawe mai i ngā tono whai hua mō ngā mākete ahumahi nui ki te mākete."
