Electrode Sapphire Substrate na Wafer C-indege LED Substrates

Ibisobanuro bigufi:

Hashingiwe ku kuzamura ubudahwema ikoranabuhanga rya safiro no kwaguka byihuse ku isoko rya porogaramu, waferi ya santimetero 4 na 6 za substrate wafers izakirwa cyane n’amasosiyete akomeye ya chip bitewe n’inyungu zabo bwite mu gukoresha umusaruro.

Safiro nkumuzunguruko wa semiconductor

Wafers yoroheje ni yo ya mbere yatsindiye gukoresha insimburangingo ya insuline yashyizwemo silikoni kugira ngo ihimbe imiyoboro ihuriweho yitwa silicon kuri safiro (SOS). Usibye kuba ifite amashanyarazi meza cyane, safiro ifite ubushyuhe bwinshi bwumuriro. Chipo ya CMOS kuri safiro irakwiriye cyane cyane kumashanyarazi akoresha ingufu nyinshi (RF) nka terefone zigendanwa, amaradiyo yumutekano rusange hamwe na sisitemu yitumanaho rya satelite.

Wafers imwe ya kristu ya safiro nayo ikoreshwa nka substrate mu nganda ziciriritse kugirango zikure gallium nitride (GaN). Gukoresha safiro bigabanya cyane ikiguzi kuko ni 1/7 cyigiciro cya germanium.GaN kuri safiro ikunze gukoreshwa mumatara yubururu asohora diode (LED).

Koresha nk'ibikoresho by'idirishya

Sintetike ya sintetike (rimwe na rimwe yitwa ikirahuri cya safiro) ikoreshwa nk'ibikoresho by'idirishya kuko iba igaragara neza hagati ya nm 150 (ultraviolet) na 5500 nm (infrared) yumurambararo wumucyo (spekure igaragara iri hagati ya 380 nm na 750 nm) kandi ifite imbaraga nyinshi zo kurwanya gushushanya. Ibyiza byingenzi bya windows ya safiro
