Ukubuka konke kwe-Sapphire Square Blank Substrate

I-substrate engenalutho yesikwele se-sapphire, njengoba kuboniswe esithombeni, iyisakhi se-aluminium oxide (Al₂O₃) esihlanzekile kakhulu esenzelwe ukusetshenziswa kubunjiniyela bokukhanya obuthuthukisiwe, ukukhiqizwa kwamadivayisi e-semiconductor, kanye nokuhlolwa kwemishini yokunemba. Idume ngezakhiwo zayo eziyingqayizivele zomzimba nezamakhemikhali, i-sapphire isibe ngenye yezinto ezibalulekile kakhulu ezimbonini ezidinga ukuqina okukhulu, ukuzinza, kanye nokusebenza kokukhanya. Ikhiqizwa ngezindlela zokukhula kwekristalu eziyinkimbinkimbi, njengezinqubo ze-Kyropoulos (KY), i-Heat Exchange Method (HEM), noma i-Czochralski (CZ), lezi zikhala zesikwele zenziwe ngokucophelela ukuze zihlangabezane nezindinganiso zekhwalithi ephezulu.

Izici Eziyinhloko Ze-Sapphire Square Blank Substrate

I-Sapphire iyikristalu e-uniaxial, anisotropic enesakhiwo se-lattice esinama-hexagonal, enikeza inhlanganisela engenakuqhathaniswa yamandla omshini, ukuzinza kokushisa, kanye nokumelana namakhemikhali. Ngesilinganiso sokuqina kwe-Mohs esingu-9, i-sapphire ilandela idayimane kuphela ngokumelana nokuklwebheka, iqinisekisa ukuhlala isikhathi eside kakhulu ngisho nangaphansi kwezimo zezimboni ezihuquzelayo. Indawo yayo yokuncibilika idlula u-2000°C, okuvumela ukusebenza okuthembekile ezindaweni ezishisa kakhulu, kuyilapho ukulahleka kwayo okuphansi kwe-dielectric kuyenza ibe yinto ethandwayo ye-RF kanye nezinhlelo zokusebenza ze-elekthronikhi ezivame kakhulu.

Esigabeni se-optical, i-sapphire ibonisa ububanzi bokudlulisa kusukela ku-ultraviolet ejulile (~200nm) kuya kokubonakalayo kuya ku-mid-infrared (~5000nm), enobunye obuhle kakhulu be-optical kanye ne-birefringence ephansi uma iqondiswe kahle. Lezi zakhiwo zenza izikhala zesikwele ze-sapphire zibaluleke kakhulu emikhakheni edinga kakhulu i-optics njengezinhlelo ze-laser, i-photonics, i-spectroscopy, kanye ne-imaging.

Ukukhiqiza Nokucubungula

I-substrate ngayinye engenalutho yesikwele se-sapphire idlula enkambisweni yokukhiqiza eqinile, iqala ngama-powder e-alumina eluhlaza ahlanzekile kakhulu afakwa ekukhuleni kwekristalu okulawulwayo ezithandweni zokushisa okuphezulu. Ngemva kokuba ikristalu enkulu isikhulile, iqondiswa ngqo (ngokuvamile i-C-plane (0001), i-A-plane (11-20), noma i-R-plane (1-102)) ukuze ivumelane nezidingo ezithile zesicelo. Ikristalu bese isikwa ibe yizikwele ezingenalutho ngamasaha ambozwe ngedayimane, kulandelwe ukugoqa okunembile ukuze kufezwe ukufana kobukhulu. Ekusetshenzisweni kwe-optical kanye ne-semiconductor, izindawo zingapholishwa zibe bushelelezi ezingeni le-athomu, zihlangabezane nokuthamba okuqinile, ukufana, kanye nokucaciswa kobulukhuni bobuso.
