12 nti Dia300x1.0mmt Sapphire Wafer Substrate C-Plane SSP / DSP

Lus piav qhia luv luv:

Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, cov kev xav tau tshiab rau qhov loj thiab zoo ntawm cov ntaub ntawv siv lead ua sapphire tau muab tso rau pem hauv ntej. Tam sim no, nrog txoj kev loj hlob sai ntawm semiconductor teeb pom kev zoo thiab lwm yam kev siv tshiab, kev ua lag luam rau tus nqi qis, zoo, loj loj sapphire crystals yog nthuav heev.

12inch Sapphire Substrate Kev Lag Luam Kev Lag Luam

Tam sim no, sapphire muaj ob qho tseem ceeb siv, ib qho yog cov khoom siv substrate, uas yog cov khoom siv LED substrate, lwm qhov yog lub xov tooj saib, aviation, aerospace, tshwj xeeb tsim cov khoom siv qhov rais.

Txawm hais tias silicon carbide, silicon thiab gallium nitride kuj muaj nyob rau hauv substrates rau leds ntxiv rau sapphire, loj ntau lawm tseem tsis tau vim nqi thiab ib co unsolved technical bottlenecks. Sapphire substrate los ntawm kev txhim kho nyob rau hauv xyoo tas los no, nws cov lattice txuam, hluav taws xob conductivity, mechanical zog, thermal conductivity thiab lwm yam khoom tau zoo heev txhim kho thiab txhawb, nqi-zoo kom zoo dua yog qhov tseem ceeb, yog li sapphire tau dhau los ua cov khoom lag luam zoo tshaj plaws thiab ruaj khov substrate. nyob rau hauv kev lag luam LED, tau dav siv nyob rau hauv kev ua lag luam, kev ua lag luam feem ntau li 90%.

Yam ntxwv Ntawm 12 Nti Sapphire Wafer Substrate

1. Sapphire substrate nto muaj qhov tsis tshua muaj qhov suav, nrog tsawg dua 50 cov khoom siv 0.3 microns lossis loj dua rau 2 ntiv tes hauv qhov loj ntawm 2 txog 8 nti, thiab cov hlau loj (K, Ti, Cr, Mn, Fe, Co, Ni , Cu, Zn) hauv qab 2E10/cm2. Cov khoom siv 12-nti kuj tseem xav kom ua tiav qib no.
2. tuaj yeem siv los ua cov khoom thauj khoom wafer rau 12-nti semiconductor manufacturing txheej txheem (hauv-device thauj pallets) thiab ua substrate rau kev sib txuas.
3. tuaj yeem tswj cov duab ntawm concave thiab convex nto.
Khoom siv: High purity ib leeg siv lead ua Al2O3, sapphire wafer.
LED zoo, tsis muaj npuas, tawg, ntxaib, kab, tsis muaj xim .. thiab lwm yam.
