Chidule cha Sapphire Square Blank Substrate

Chophimba chopanda kanthu cha safiro, monga momwe chikusonyezedwera pachithunzichi, ndi chinthu choyera kwambiri cha single-crystal aluminum oxide (Al₂O₃) chomwe chimapangidwa kuti chigwiritsidwe ntchito muukadaulo wapamwamba wa kuwala, kupanga zida za semiconductor, komanso kuyesa zida zolondola. Chodziwika bwino chifukwa cha mphamvu zake zapadera zakuthupi ndi zamakemikolo, safiro yakhala imodzi mwa zipangizo zofunika kwambiri m'mafakitale omwe amafuna kulimba kwambiri, kukhazikika, komanso magwiridwe antchito a kuwala. Chopangidwa kudzera mu njira zamakono zokulira makristalo, monga Kyropoulos (KY), Heat Exchange Method (HEM), kapena Czochralski (CZ), malo obisika awa amapangidwa mosamala kwambiri kuti akwaniritse miyezo yapamwamba kwambiri.

Zinthu Zofunika Kwambiri za Sapphire Square Blank Substrate

Sapphire ndi kristalo ya uniaxial, anisotropic yokhala ndi mawonekedwe a hexagonal lattice, yomwe imapereka kuphatikiza kosayerekezeka kwa mphamvu yamakina, kukhazikika kwa kutentha, komanso kukana mankhwala. Ndi mulingo wa Mohs hardness wa 9, safiro ndi yachiwiri pambuyo pa diamondi pankhani ya kukana kukanda, zomwe zimapangitsa kuti ikhale ndi moyo wautali ngakhale m'mafakitale ovuta. Malo ake osungunuka amaposa 2000°C, zomwe zimapangitsa kuti ikhale yodalirika m'malo otentha kwambiri, pomwe kutayika kwake kochepa kwa dielectric kumapangitsa kuti ikhale chinthu chogwiritsidwa ntchito kwambiri pa RF ndi ma electronic frequency.

Mu gawo la kuwala, safiro imawonetsa kufalikira kwakukulu kuyambira pa ultraviolet yakuya (~200nm) mpaka yowoneka mpaka yapakati pa infrared (~5000nm), yokhala ndi mawonekedwe ofanana bwino komanso birefringence yochepa ikayang'aniridwa bwino. Makhalidwe amenewa amapangitsa kuti malo obisika a safiro akhale ofunikira kwambiri m'magawo omwe amagwiritsa ntchito kuwala monga laser systems, photonics, spectroscopy, ndi kujambula zithunzi.

Kupanga ndi Kukonza

Gawo lililonse lopanda kanthu la safiro limakhala ndi njira yokhwima yopangira, kuyambira ndi ufa wa alumina wosaphika woyera kwambiri womwe umayikidwa mu ng'anjo yotentha kwambiri. Kristalo wochuluka akakula, amayikidwa molunjika (nthawi zambiri C-plane (0001), A-plane (11-20), kapena R-plane (1-102)) kuti agwirizane ndi zofunikira za ntchitoyo. Kristaloyo imadulidwa m'magawo osalala ndi macheka okhala ndi diamondi, kutsatiridwa ndi kulumikiza molondola kuti makulidwe akhale ofanana. Pa ntchito za kuwala ndi semiconductor, malo amatha kupukutidwa kuti akhale osalala, akwaniritse kusalala kolimba, kufanana, ndi mawonekedwe a pamwamba.

Ubwino Waukulu

Kuwonekera Kwabwino Kwambiri kwa Maso- Kutumiza kwa wideband kuchokera ku UV kupita ku IR kumapangitsa kuti ikhale yoyenera mawindo owoneka bwino, ma laser cavities, ndi zophimba masensa.
Mphamvu Zapamwamba Zamakina- Mphamvu yolimba kwambiri, kulimba kwa kusweka, komanso kukana kukanda kumathandiza kuti munthu akhale ndi moyo wautali m'malo omwe ali ndi nkhawa kwambiri.
Kukhazikika kwa Kutentha ndi Mankhwala- Yolimba ku kutentha, kutentha kwambiri, ndi mankhwala amphamvu, imasunga umphumphu panthawi yokonza zinthu za semiconductor komanso kukhudzidwa kwambiri ndi chilengedwe.
Kulamulira Koyenera kwa Miyeso- Kulekerera makulidwe komwe kungatheke mkati mwa ±5µm ndi kusalala kwa pamwamba mpaka λ/10 (pa 632.8nm), kofunikira kwambiri pakugwiritsa ntchito photolithography ndi wafer bonding.
Kusinthasintha- Yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo zinthu zowunikira, zinthu zokulitsa za epitaxial, ndi ma wafer oyesera makina.

Mapulogalamu

Mapulogalamu Owoneka: Amagwiritsidwa ntchito ngati mawindo, zosefera, zogwirira ntchito za laser gain medium, zophimba zoteteza masensa, ndi zinthu za photonics chifukwa cha kumveka bwino kwake komanso kulimba kwake.
Ma Substrate a Semiconductor: Imagwira ntchito ngati maziko oyambira a ma LED ozikidwa pa GaN, zamagetsi zamagetsi (zomangamanga za SiC-on-saphire), zida za RF, ndi ma circuits a microelectronic, komwe kutentha ndi kukana mankhwala ndizofunikira kwambiri.
Kuyesa Zida ndi Ma Wafer Osafunikira: Kawirikawiri amagwiritsidwa ntchito ngati zinthu zoyesera m'mizere yopanga semiconductor, zomwe zimagwiritsidwa ntchito poyesa makina, kuyerekezera njira, komanso kuyesa kupirira kwa zida zolembera, zoyika, kapena zowunikira.
Kafukufuku wa Sayansi: Zofunikira pakukonzekera koyesera komwe kumafuna nsanja zosagwira ntchito, zowonekera bwino, komanso zokhazikika pamakanika kuti zigwiritsidwe ntchito pofufuza za kuwala, zamagetsi, ndi zinthu.

FAQ

Q1: Kodi ubwino wogwiritsa ntchito safiro wozungulira wopanda kanthu ndi wotani?
A: Malo opanda sikweya amapereka malo okwanira ogwiritsira ntchito kudula mwamakonda, kupanga zida, kapena kuyesa makina, kuchepetsa kutaya kwa zinthu ndi mtengo wake.

Q2: Kodi ma substrates a safiro amatha kupirira malo ogwiritsira ntchito semiconductor?
A: Inde, zinthu zopangidwa ndi safiro zimasunga kukhazikika pansi pa kutentha kwambiri, kupukutidwa kwa plasma, ndi mankhwala omwe amagwiritsidwa ntchito popanga zinthu zopangidwa ndi semiconductor.
