Chigawo cha Sapphire cha Electrode ndi Chigawo cha LED cha Wafer C-plane

Kufotokozera Kwachidule:

Kutengera kukweza kosalekeza kwa ukadaulo wa safiro komanso kukula kwa msika wogwiritsa ntchito, ma wafer a substrate a mainchesi 4 ndi mainchesi 6 adzagwiritsidwa ntchito kwambiri ndi makampani akuluakulu a chip chifukwa cha zabwino zomwe amagwiritsa ntchito popanga.

Safira ngati gawo lothandizira pa semiconductor circuit

Ma wafer owonda a safiro anali oyamba kugwiritsa ntchito bwino chinthu chotetezera kutentha chomwe chinayikidwapo silicon kuti chipange ma circuits ophatikizidwa otchedwa silicon on safiro (SOS). Kuwonjezera pa mphamvu zake zabwino kwambiri zotetezera kutentha, safiro ili ndi mphamvu zambiri zotenthetsera kutentha. Ma chips a CMOS pa safiro ndi oyenera makamaka kugwiritsa ntchito ma radio frequency amphamvu kwambiri (RF) monga mafoni am'manja, ma radio a chitetezo cha anthu onse ndi makina olumikizirana ndi satelayiti.

Ma wafer a safiro amodzi amagwiritsidwanso ntchito ngati zinthu zoyambira mumakampani opanga ma semiconductor polima zida zopangidwa ndi gallium nitride (GaN). Kugwiritsa ntchito safiro kumachepetsa kwambiri mtengo chifukwa ndi pafupifupi 1/7 ya mtengo wa germanium. GaN pa safiro imagwiritsidwa ntchito kwambiri mu ma LED otulutsa kuwala kwabuluu.

Gwiritsani ntchito ngati zinthu zomangira pawindo

Sapphire yopangidwa (nthawi zina imatchedwa galasi la safiro) nthawi zambiri imagwiritsidwa ntchito ngati zinthu zomangira pazenera chifukwa imakhala yowonekera bwino pakati pa 150 nm (ultraviolet) ndi 5500 nm (infrared) wavelengths ya kuwala (mawonekedwe owonekera amayambira pa 380 nm mpaka 750 nm) ndipo imakana kwambiri kukanda. Ubwino waukulu wa mawindo a safiro

Phatikizanipo

Bandwidth yolumikizira kuwala kwambiri, kuyambira UV mpaka kuwala kwapafupi ndi infrared

Yolimba kuposa zipangizo zina zowunikira kapena mawindo agalasi

Yolimba kwambiri kukanda ndi kukanda (kulimba kwa mchere kwa 9 pa sikelo ya Mohs, yachiwiri kwa diamondi ndi moissanite pakati pa zinthu zachilengedwe)

Malo osungunuka kwambiri (2030°C)
