Ma Electrode Sapphire Substrate ndi Wafer C-ndege Magawo a LED

Kufotokozera Kwachidule:

Kutengera kukwezera kosalekeza kwaukadaulo wa safiro komanso kukulirakulira kwa msika wogwiritsa ntchito, zowotcha zazing'ono za mainchesi 4 ndi mainchesi 6 zidzalandiridwa kwambiri ndi makampani amtundu wa chip chifukwa chaubwino wawo wogwiritsa ntchito popanga.

Sapphire ngati gawo la gawo la semiconductor

Zophika zopyapyala za safiro zinali njira yoyamba yogwiritsira ntchito bwino kagawo kakang'ono kotsekera komwe silicon idayikidwapo kuti apange mabwalo ophatikizika otchedwa silicon pa safiro (SOS). Kuphatikiza pa zinthu zabwino kwambiri zotchinjiriza magetsi, safiro imakhala ndi ma conductivity apamwamba amafuta. CMOS chips pa safiro ndizoyenera kwambiri kugwiritsa ntchito ma radio frequency (RF) amphamvu kwambiri monga mafoni am'manja, ma wayilesi oteteza chitetezo cha anthu ndi njira zolumikizirana za satellite.

Zophika za safiro limodzi za safiro zimagwiritsidwanso ntchito ngati magawo am'magawo a semiconductor pokulitsa zida za gallium nitride (GaN). Kugwiritsa ntchito safiro kumachepetsa kwambiri ndalama chifukwa ndi pafupifupi 1/7th mtengo wa germanium.GaN pa safiro amagwiritsidwa ntchito kwambiri mu blue light emitting diodes (LEDs).

Gwiritsani ntchito ngati zenera zakuthupi

Sapphire yopangidwa (nthawi zina amatchedwa galasi la safiro) nthawi zambiri imagwiritsidwa ntchito ngati zenera chifukwa imawonekera kwambiri pakati pa 150 nm (ultraviolet) ndi 5500 nm (infrared) wavelengths wa kuwala (mawonekedwe owoneka bwino amachokera pafupifupi 380 nm mpaka 750 nm) ndipo ali ndi kukana kwambiri kukanda. Ubwino waukulu wa mawindo a safiro
