AlN-on-NPSS Wafer: Chophimba cha Aluminium Nitride Chogwira Ntchito Kwambiri pa Substrate Yopanda Kupukutidwa ya Sapphire Yogwiritsidwa Ntchito Pakutentha Kwambiri, Mphamvu Yaikulu, ndi RF

AlN-on-NPSS Wafer: Gawo la Aluminiyamu la Nitride Logwira Ntchito Kwambiri pa Substrate Yopanda Kupukutidwa ya Sapphire Yogwiritsidwa Ntchito Pakutentha Kwambiri, Mphamvu Yaikulu, ndi RF Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Wafer wa AlN-on-NPSS umaphatikiza wosanjikiza wa aluminiyamu nitride (AlN) wochita bwino kwambiri ndi sapphire substrate yosapukutidwa (NPSS) kuti ipereke yankho labwino kwambiri pakugwiritsa ntchito kutentha kwambiri, mphamvu zambiri, komanso ma radio-frequency (RF). Kuphatikiza kwapadera kwa mphamvu ya AlN yotenthetsera kutentha komanso mphamvu zamagetsi, pamodzi ndi mphamvu yabwino kwambiri ya makina a substrate, kumapangitsa wafer iyi kukhala chisankho chabwino kwambiri pakugwiritsa ntchito zinthu zovuta monga zamagetsi zamagetsi, zida zama frequency apamwamba, ndi zida zowunikira. Ndi kutentha kwambiri, kutayika kochepa, komanso kugwirizana ndi malo otentha kwambiri, wafer iyi imalola kupanga zida zam'badwo wotsatira zomwe zimagwira ntchito bwino kwambiri.

Gawo la AlN Logwira Ntchito KwambiriAluminium Nitride (AlN) imadziwika chifukwa chakutentha kwakukulu(~200 W/m·K),mpata waukulundimagetsi owonongeka kwambiri, zomwe zimapangitsa kuti ikhale chinthu choyenera kwambiriamphamvu kwambiri, pafupipafupi kwambirindikutentha kwambirimapulogalamu.

Chosapukutidwa cha Sapphire Substrate (NPSS): Safire yosapukutidwa imaperekayotsika mtengo, yolimba kwambiri pamakinamaziko, kuonetsetsa kuti maziko ake ndi olimba kuti epitaxial ikule popanda kupukuta pamwamba. Kapangidwe kabwino ka makina a NPSS kamathandiza kuti ikhale yolimba m'malo ovuta.

Kukhazikika Kwambiri kwa Kutentha: Wafer ya AlN-on-NPSS imatha kupirira kusinthasintha kwakukulu kwa kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito muzamagetsi zamagetsi, makina a magalimoto, Ma LEDndintchito zowunikirazomwe zimafuna kuti ntchito ikhale yokhazikika pa kutentha kwambiri.

Kuteteza Magetsi: AlN ili ndi mphamvu zabwino kwambiri zotetezera magetsi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pamenekudzipatula kwa magetsindikofunikira kwambiri, kuphatikizapoZipangizo za RFndizamagetsi a microwave.

Kutaya Kutentha Kwambiri: Ndi kutentha kwambiri, AlN layer imatsimikizira kuti kutentha kumataya bwino, zomwe ndizofunikira kuti zipangizo zigwire ntchito bwino komanso zizikhala nthawi yayitali.
