Monga mabwalo ophatikizika asanduka makampani odziwika bwino padziko lonse lapansi, zida zambiri zama semiconductor zidafufuzidwa ndikupangidwa, ndipo Aluminium Nitride mosakayikira ndi imodzi mwazinthu zodalirika kwambiri zama semiconductor.
Aluminium Nitride Performance Makhalidwe
Aluminiyamu Nitride (AlN) ali ndi makhalidwe a mphamvu mkulu, mkulu voliyumu resistivity, mkulu kutchinjiriza voteji, coefficient wa kukulitsa matenthedwe, kufananitsa bwino ndi silicon, etc. Sitikugwiritsidwa ntchito ngati sintering thandizo kapena kulimbikitsa gawo kwa ziwiya zadothi structural komanso ntchito. m'munda wa magawo amagetsi a ceramic ndi zida zoyika, zomwe zakhala zikuyenda bwino m'zaka zaposachedwa, ndipo magwiridwe ake amaposa a Alumina. Aluminiyamu Nitride ceramics ali ndi magwiridwe antchito abwino kwambiri, ndi abwino kwa magawo a semiconductor ndi zida zomangirira, ndipo ali ndi kuthekera kofunikira pamakampani opanga zamagetsi.
Kugwiritsa ntchito Aluminium Nitride
1. Pazida za piezoelectric
Aluminiyamu Nitride ali ndi resistivity mkulu, mkulu matenthedwe madutsidwe, ndi otsika coefficient oftukuka ofanana ndi silicon, amene ndi zinthu zabwino kwambiri kutentha ndi mkulu-mphamvu zipangizo zamagetsi.
2. Zinthu zopakira pakompyuta
Beryllium Oxide, Alumina, Silicon Nitride, ndi Aluminium Nitride ndi zina mwazinthu zomwe zimagwiritsidwa ntchito popanga magawo a ceramic.
Pakati pa zida za ceramic zomwe zingagwiritsidwe ntchito ngati zida zapansi panthaka, zoumba za Silicon Nitride zimakhala ndi mphamvu zosunthika kwambiri, kukana kuvala bwino, komanso makina abwino kwambiri azinthu zadothi, pomwe gawo lawo lakukula kwamafuta ndilochepa kwambiri. Aluminiyamu Nitride ceramics ali ndi matenthedwe apamwamba kwambiri, kukana kwamphamvu kwamafuta, ndipo amakhalabe ndi zida zabwino zamakina kutentha kwambiri. Zinganenedwe kuti, poyang'ana ntchito, Aluminium Nitride ndi Silicon Nitride panopa ndizoyenera kwambiri kugwiritsidwa ntchito ngati zipangizo zamagetsi zamagetsi, koma amakhalanso ndi vuto lofanana: mtengo wawo ndi wapamwamba.
3. Kugwiritsa ntchito zinthu zotulutsa kuwala
Pankhani ya photoelectric kutembenuka bwino, aluminium nitride (AlN) ali mwachindunji bandgap semiconductor bandi pazipita m'lifupi mwake 6.2 eV, amene ndi apamwamba kuposa indirect bandgap semiconductor. AlN, monga chinthu chofunika kwambiri cha buluu ndi ultraviolet chotulutsa kuwala, chimagwiritsidwa ntchito mu ultraviolet ndi deep ultraviolet kuwala-emitting diode, ultraviolet laser diode, ultraviolet detectors, ndi zina zotero. yankho, ndi kusiyana kwa gulu la aloyi yake ya ternary kapena quaternary imatha kusinthidwa mosalekeza kuchokera ku gulu lowoneka kupita ku gulu lakuya la ultraviolet, ndikupangitsa kuti ikhale yofunika kwambiri yotulutsa kuwala.
4. Kugwiritsa ntchito zinthu zapansi panthaka
AlN crystal ndiye gawo lapansi loyenera la zida za GaN, AlGaN, ndi AlN epitaxial. Poyerekeza ndi safiro kapena ma SiC substrates, AlN ndi GaN ali ndi matenthedwe abwinoko ofananirako komanso ogwirizana ndi mankhwala, ndipo kupsinjika pakati pa gawo lapansi ndi gawo la epitaxial ndikocheperako. Choncho, makhiristo a AlN monga magawo a GaN epitaxial amatha kuchepetsa kwambiri kuwonongeka kwa chilema mu chipangizocho ndikuwongolera ntchito yake, yomwe ili ndi chiyembekezo chabwino kwambiri chogwiritsira ntchito pokonzekera zipangizo zamakono zotentha kwambiri, zothamanga kwambiri, komanso zamphamvu kwambiri. Kuonjezera apo, kugwiritsa ntchito makhiristo a AlN monga gawo laling'ono la AlGaN epitaxial lomwe lili ndi zigawo zambiri za aluminiyamu (Al) kungathenso kuchepetsa kuchepa kwa chilema mu nitride epitaxial layer ndikuwongolera kwambiri ntchito ndi moyo wonse wa zipangizo za nitride semiconductor. Kutengera AlGaN, chowunikira chapamwamba kwambiri chatsiku chagwiritsidwa ntchito bwino.
5. Kugwiritsa ntchito zida zadothi ndi zowuma
Aluminiyamu nitride angagwiritsidwe ntchito structural ceramic sintering; okonzeka Aluminiyamu Nitride zadothi si bwino mawotchi katundu ndi mphamvu flexural kuposa Al2O3 ndi BeO zadothi, komanso apamwamba kuuma ndi dzimbiri kukana. Pogwiritsa ntchito kukana kutentha ndi kukokoloka kwa ziwiya zadothi AlN, angagwiritsidwe ntchito kupanga crucibles, Al evaporation mbale, ndi mbali zina zosatentha kwambiri kuti zisawonongeke. Kuphatikiza apo, zoumba zoyera za AlN zamakristali osawoneka bwino, okhala ndi mawonekedwe owoneka bwino, atha kugwiritsidwa ntchito ngati zoumba zowonekera pazida zamagetsi zamagetsi ndi zida zamawindo otentha kwambiri komanso zokutira zosagwira kutentha.
