2 nti 4 nti 6 nti 6 nti qauv sapphire substrate (pss) ntawm uas gan cov khoom siv tau rau coj teeb pom kev zoo

Cov lus piav qhia luv luv:

Txawv sapphire substrate (pss) yog lub ntsej muag rau qhuav ntawm lub sapphood txheej txheem, thiab tom qab ntawd lub ntsej muag yog mus rau ntawm nws, yog li ntawd cov khoom siv gan ntev ntawm Gan cov khoom lag luam tiav. Tus txheej txheem no suav nrog ntau kauj ruam xws li cov txheej txheem photoresist, kauj ruam raug, tsim cov qauv raug, icp qhuav etching thiab tu.

Cov yam ntxwv tseem ceeb

1. Cov Qauv Txheej Txheem:
PSs nto muaj ib tug txheej txheem confe los yog kab ke lus qhia txog tus qauv uas nws lub cev, qhov loj me tuaj yeem tswj tau los ntawm kev kho cov txheej txheem etching.
Cov qauv duab duab no pab hloov txoj kev hais tawm ntawm lub teeb thiab txo kev xav txog tag nrho cov kev xav ntawm lub teeb kev rho tawm.

2. Cov yam ntxwv cov yam ntxwv:
PSs siv cov sapphire siab, uas muaj cov yam ntxwv ntawm kev nyuaj, siab thermal condability thiab kho qhov muag.
Cov yam ntxwv no siv cov cim kom tiv thaiv cov chaw hnyav xws li cov kub thiab ntsuas thaum tswj kev ua haujlwm zoo.

3. Kev Ua Haujlwm Kho Mob:
Los ntawm kev hloov ntau qhov tawg ntawm lub interface ntawm gan thiab sapphire substrate, pss ua rau lub photons uas tau pom me me hauv gan muaj sijhawm khiav tawm ntawm sapphire substrate.
Qhov no tshwj xeeb txhim kho lub teeb extraction ntawm lub LED thiab txhim kho kev siv luminous ntawm LED.

4. Txheej Txheem Txheej Txheem:
Cov txheej txheem tsim khoom ntawm cov pss yog qhov sib txawv, koom nrog ntau cov kauj ruam xws li li teb thiab etching, thiab yuav tsum muaj cov cuab yeej siv ntsuas thiab tswj cov txheej txheem siab.
Txawm li cas los xij, nrog kev nce qib nruam ntawm kev siv tshuab thiab kev txo tus nqi, kev tsim khoom ntawm cov pss yog maj mam ua kom zoo thiab txhim kho.

Cov tau zoo dua

1.Qhov teeb tsa lub teeb pom kev ua tau zoo: PSs txhim kho lub teeb extraction ntawm coj los hloov lub teeb pom kev zoo txoj kev thiab txo qhov kev xav txog tag nrho.

2. Crodrolong LED LED cov ntaub ntawv tsis sib haum ntawm Gan cov ntaub ntawv tsis raug, yog li txo qhov chaw so hluav taws xob thiab rov qab ua haujlwm tam sim no, txuas ntxiv lub neej ntawm coj.

3.Cov teeb meem LED BL ci: Vim muaj kev txhim kho ntawm lub teeb kev rho tawm thiab txuas ntxiv ntawm LED lub neej, lub LED luminous siv rau cov pss yog txhim kho.

4.Leduws cov nqi ntau lawm: txawm hais tias kev tsim khoom lag luam ntawm cov pss yog qhov ua tau zoo, nws tuaj yeem txhim kho cov nqi luminous thiab lub neej muaj qee yam thiab txhim kho cov kev sib tw ntawm cov khoom lag luam.

Daim ntawv thov tseem ceeb

1. LED teeb pom kev zoo: PSs raws li cov khoom siv substrate rau cov khoom siv led, tuaj yeem txhim kho lub luminous efficiency thiab lub neej ntawm coj.
Hauv tshav teb ntawm LED teeb pom kev zoo, PSs yog siv nyob rau hauv ntau lub teeb pom kev zoo, xws li txoj kev teeb lub neej, lub rooj teeb, lub tsheb teeb thiab lwm yam.

2.Samsonductor cov cuab yeej: ntxiv rau kev teeb pom kev zoo, pss kuj tseem siv tau lwm yam kev siv hauv kev sib txuas lus, kev kho mob, tub rog thiab lwm daim teb.

3.Txoj kev sib xyaw ua ke: Cov khoom kho tshiab thiab ruaj khov ntawm cov khoom siv uas tsim nyog, PSs kho kom zoo nkauj.
