I-Sapphire njenge-semiconductor circuit substrate
Amawafa amasafire azacile ayewukusetshenziswa kokuqala ngempumelelo kwe-substrate evikelayo lapho i-silicon yayifakwa khona ukuze kwenziwe amasekethe ahlanganisiwe abizwa ngokuthi i-silicon on sapphire (SOS). Ngaphezu kwezakhiwo zayo ezinhle kakhulu zokuvala ugesi, isafire ine-conductivity ephezulu yokushisa.Ama-CMOS ama-chip kusafire afaneleka ngokukhethekile izinhlelo zokusebenza zomsakazo wamandla aphezulu (RF) ezifana nomakhalekhukhwini, imisakazo yebhendi yokuphepha yomphakathi kanye nezinhlelo zokuxhumana ngesathelayithi.
Amawafa e-crystal sapphire eyodwa nawo asetshenziswa njengama-substrates embonini ye-semiconductor ekukhuliseni amadivayisi asekelwe ku-gallium nitride (GaN). Ukusetshenziswa kwesafire kunciphisa kakhulu izindleko njengoba cishe 1/7th izindleko ze-germanium.I-GaN kusafire ivame ukusetshenziswa kuma-blue light emitting diodes (LEDs).
Sebenzisa njengefasitela impahla
Isafire yokwenziwa (ngezinye izikhathi ebizwa ngokuthi ingilazi yesafire) ivamise ukusetshenziswa njengefasitela ngoba ikhanye kakhulu phakathi kuka-150 nm (ultraviolet) kanye no-5500 nm (infrared) wamaza okukhanya (ububanzi obubonakalayo busuka cishe ku-380 nm kuya ku-750 nm) futhi inokumelana okuphezulu kakhulu nokunwaya. Izinzuzo eziyinhloko zamafasitela esafire
Faka
I-bandwidth yokubona ebanzi kakhulu, ukusuka ku-UV ukuya ekukhanyeni okuseduze kwe-infrared
Iqinile kunezinye izinto ezibonakalayo noma amafasitela engilazi
Imelana kakhulu nokuklwejwa kanye nokuhuzuka (ukuqina kwamaminerali okungu-9 esikalini se-Mohs, okwesibili ngemva kwedayimane ne-moissanite phakathi kwezinto zemvelo)
Indawo yokuncibilika ephezulu kakhulu (2030°C)
