Dia50.8 × 0.1 / 0.17 / 0.2 / 0.25 / 0.3mmt Sapphire Wafer substrate Epi-npaj DSP SSP

Lus piav qhia luv luv:

Lub 2-nti sapphire wafer yog cov khoom siv zoo nrog lub siab tawv, siab melting point thiab zoo tshuaj stability.

Product Detail

Khoom cim npe

Hauv qab no yog 2inch Sapphire Wafer piav qhia, xwm zoo, kev siv dav dav thiab tus qauv wafer parameter ntsuas txog 2-nti sapphire wafers:

Cov lus piav qhia: 2 nti sapphire wafers yog tsim los ntawm kev txiav cov sapphire ib leeg siv lead ua khoom rau hauv silicon wafer zoo nrog ib tug du thiab tiaj tus. Nws yog cov khoom siv ruaj khov thiab ruaj khov siv dav hauv optics, electronics thiab photonics.

Cov Khoom Zoo Zoo

High hardness: Sapphire muaj Mohs hardness theem ntawm 9, thib ob tsuas yog pob zeb diamond, ua rau muaj kev khawb zoo heev thiab hnav tsis kam.

Siab melting point: Sapphire muaj qhov melting point ntawm kwv yees li 2040 ° C, ua rau nws ua hauj lwm nyob rau hauv high-kub ib puag ncig nrog zoo thermal stability.

Chemical stability: Sapphire muaj tshuaj lom neeg ruaj khov thiab tiv taus cov kua qaub, alkalis thiab corrosive gases, ua rau nws tsim nyog rau kev siv hauv ntau qhov chaw hnyav.

Kev siv dav dav

Kev siv kho qhov muag: sapphire wafers tuaj yeem siv rau hauv laser tshuab, kho qhov muag qhov rais, lo ntsiab muag, infrared optics li, thiab lwm yam. Vim nws cov pob tshab zoo heev, sapphire tau siv dav hauv qhov chaw kho qhov muag.

Kev siv hluav taws xob: Sapphire wafers tuaj yeem siv rau hauv kev tsim cov diodes, LEDs, laser diodes thiab lwm yam khoom siv hluav taws xob. Sapphire muaj cov thermal conductivity zoo thiab hluav taws xob rwb thaiv tsev, haum rau cov khoom siv hluav taws xob muaj zog.

Kev siv Optoelectronic: Sapphire wafers tuaj yeem siv los tsim cov duab sensors, photodetectors thiab lwm yam khoom siv optoelectronic. Sapphire qhov poob qis thiab cov lus teb siab ua rau nws zoo tagnrho rau kev siv optoelectronic.

Standard wafer parameter specifications:

Txoj kab uas hla: 2 nti (kwv yees 50.8 mm)

Thickness: Feem ntau thicknesses xws li 0.5 hli, 1.0 hli, thiab 2.0 hli. Lwm cov thicknesses tuaj yeem kho raws li qhov kev thov.

Deg roughness: Feem ntau Ra <0.5 nm.

Ob-sided polishing: flatness feem ntau <10 µm.

Ob sab polished ib leeg siv lead ua sapphire wafers: wafers polished ntawm ob sab thiab nrog rau qib siab dua ntawm kev sib luag rau cov ntawv thov uas xav tau ntau dua.

Thov nco ntsoov tias cov khoom tshwj xeeb tsis tuaj yeem sib txawv raws li qhov xav tau ntawm cov chaw tsim khoom thiab daim ntawv thov.
