● Qhov Loj:GaN tso cai rau kev tsim cov khoom siv sib xyaw ua ke ntau dua thiab lub teeb yuag piv rau cov khoom siv hluav taws xob ib txwm muaj, ua kom yooj yim rau cov khoom siv hluav taws xob me me thiab muaj zog dua.

Abstract

Gallium Nitride (GaN) tau tshwm sim los ua tus semiconductor ntawm kev xaiv rau cov ntawv thov siab heev uas xav tau lub zog thiab kev ua haujlwm zoo, xws li RF pem hauv ntej-kawg modules, kev sib txuas lus ceev, thiab LED teeb pom kev zoo. GaN epitaxial wafers, thaum loj hlob ntawm sapphire substrates, muab kev sib xyaw ua ke ntawm cov thermal conductivity, siab tawg voltage, thiab cov lus teb dav, uas yog qhov tseem ceeb rau kev ua haujlwm zoo hauv kev sib txuas lus wireless, radars, thiab jammers. Cov wafers no muaj nyob rau hauv ob qho tib si 4-nti thiab 6-inch diameters, nrog rau qhov sib txawv GaN thicknesses kom tau raws li cov kev cai sib txawv. GaN cov khoom tshwj xeeb ua rau nws yog tus neeg sib tw tseem ceeb rau yav tom ntej ntawm lub zog hluav taws xob.

Q&A

Q1: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev siv GaN dhau ib txwm siv silicon-based semiconductors?

A1: GaN muaj ntau qhov zoo ntawm silicon, nrog rau qhov dav bandgap, uas tso cai rau nws los tswj cov hluav taws xob ntau dua thiab ua haujlwm tau zoo ntawm qhov kub siab dua. Qhov no ua rau GaN zoo tagnrho rau kev siv hluav taws xob siab, kev siv ntau zaus xws li RF modules, lub zog amplifiers, thiab LEDs. GaN lub peev xwm los tuav lub zog ntau dua kuj tseem ua rau cov khoom siv me me thiab siv tau zoo dua piv rau cov khoom siv silicon.

Q2: GaN ntawm Sapphire wafers puas tuaj yeem siv hauv MEMS (Micro-Electro-Mechanical Systems) kev siv?

A2: Yog lawm, GaN ntawm Sapphire wafers yog tsim rau MEMS daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv qhov chaw siab zog, kub stability, thiab tsis muaj suab nrov. Cov khoom siv ua haujlwm ntev thiab ua haujlwm tau zoo hauv qhov chaw muaj suab nrov ua rau nws zoo tagnrho rau MEMS cov cuab yeej siv hauv kev sib txuas lus wireless, kev paub, thiab radar systems.

Q3: Dab tsi yog qhov kev siv peev xwm ntawm GaN hauv kev sib txuas lus wireless?

A3: GaN tau siv dav hauv RF pem hauv ntej-kawg modules rau kev sib txuas lus wireless, suav nrog 5G infrastructure, radar systems, thiab jammers. Nws lub zog siab ceev thiab thermal conductivity ua rau nws zoo meej rau cov khoom siv hluav taws xob siab, cov khoom siv ntau zaus, ua kom muaj kev ua tau zoo dua thiab cov qauv me me piv rau cov kev daws teeb meem silicon.
