200 hli 8 nti GaN ntawm sapphire Epi-txheej wafer substrate
Kev taw qhia txog khoom
Lub 8-nti GaN-on-Sapphire substrate yog cov khoom siv semiconductor zoo uas muaj cov txheej Gallium Nitride (GaN) uas loj hlob ntawm Sapphire substrate. Cov khoom siv no muaj cov khoom siv hluav taws xob zoo heev thiab zoo tagnrho rau kev tsim cov khoom siv semiconductor muaj zog thiab zaus siab.
Txoj Kev Tsim Khoom
Cov txheej txheem tsim khoom suav nrog kev loj hlob epitaxial ntawm GaN txheej ntawm Sapphire substrate siv cov txheej txheem siab heev xws li hlau-organic tshuaj vapor deposition (MOCVD) lossis molecular beam epitaxy (MBE). Kev tso tawm yog ua tiav nyob rau hauv cov xwm txheej tswj hwm kom ntseeg tau tias muaj cov khoom siv crystal zoo thiab zaj duab xis sib xws.
Cov ntawv thov
Lub 8-nti GaN-on-Sapphire substrate pom ntau daim ntawv thov hauv ntau qhov chaw suav nrog kev sib txuas lus microwave, radarsystems, wireless technology, thiab optoelectronics. Qee qhov kev siv dav suav nrog:
1. Cov amplifiers fais fab RF
2. Kev lag luam teeb pom kev zoo LED
3. Cov khoom siv sib txuas lus wireless network
4. Cov khoom siv hluav taws xob rau qhov chaw kub siab
5. Ocov khoom siv ptoelectronic
Cov Lus Qhia Txog Khoom
- Qhov Loj: Qhov loj ntawm lub substrate yog 8 nti (200 hli) hauv txoj kab uas hla.
- Qhov Zoo Ntawm Qhov Chaw: Qhov chaw tau txhuam kom du thiab zoo li daim iav.
- Thickness: Lub GaN txheej thickness tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb.
- Kev Ntim Khoom: Cov khoom siv hauv qab no tau ntim zoo hauv cov khoom siv tiv thaiv hluav taws xob kom tiv thaiv kev puas tsuaj thaum thauj mus los.
- Kev Taw Qhia Tiaj: Lub substrate muaj kev taw qhia tshwj xeeb tiaj tus los pab txhawb kev sib dhos thiab kev tuav thaum lub sijhawm tsim khoom siv.
- Lwm yam kev ntsuas: Cov lus qhia tshwj xeeb ntawm qhov tuab, resistivity, thiab dopant concentration tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Nrog nws cov khoom siv zoo tshaj plaws thiab kev siv tau ntau yam, 8-nti GaN-on-Sapphire substrate yog qhov kev xaiv txhim khu kev qha rau kev txhim kho cov khoom siv semiconductor ua tau zoo hauv ntau yam lag luam.
Tsuas yog GaN-On-Sapphire xwb, peb kuj tseem tuaj yeem muab cov khoom siv fais fab rau hauv thaj chaw siv hluav taws xob, cov khoom lag luam suav nrog 8-nti AlGaN/GaN-on-Si epitaxial wafers thiab 8-nti P-cap AlGaN/GaN-on-Si epitaxial wafers. Tib lub sijhawm, peb tau tsim kho tshiab daim ntawv thov ntawm nws tus kheej 8-nti GaN epitaxy thev naus laus zis hauv thaj chaw microwave, thiab tsim 8-nti AlGaN/ GAN-on-HR Si epitaxy wafer uas sib xyaw ua ke kev ua haujlwm siab nrog qhov loj, tus nqi qis thiab sib xws nrog tus qauv 8-nti ntaus ntawv ua tiav. Ntxiv nrog rau silicon-based gallium nitride, peb kuj muaj cov kab khoom ntawm AlGaN/GaN-on-SiC epitaxial wafers kom tau raws li cov neeg siv khoom xav tau rau silicon-based gallium nitride epitaxial cov ntaub ntawv.
