2 nti Sic silicon carbide substrate 6H-N Hom 0.33mm 0.43mm ob sab polishing Siab thermal conductivity tsawg zog noj Featured duab

Lus piav qhia luv luv:

Silicon carbide (SiC) yog cov khoom siv dav dav ntawm cov khoom siv semiconductor nrog thermal conductivity thiab tshuaj lom neeg ruaj khov. Hom 6H-N qhia tias nws cov qauv siv lead ua yog hexagonal (6H), thiab "N" qhia tias nws yog N-hom semiconductor khoom, uas feem ntau ua tiav los ntawm doping nitrogen.
Lub silicon carbide substrate muaj cov yam ntxwv zoo ntawm kev ua haujlwm siab, kev kub siab, kev ua haujlwm siab, thiab lwm yam. Piv nrog cov khoom siv silicon, cov cuab yeej npaj los ntawm silicon substrate tuaj yeem txo qhov poob los ntawm 80% thiab txo cov cuab yeej loj los ntawm 90%. Nyob rau hauv cov nqe lus ntawm lub zog tshiab tsheb, silicon carbide tuaj yeem pab lub zog tshiab tsheb ua kom lub cev nyhav thiab txo qis, thiab nce kev tsav tsheb; Hauv kev sib txuas lus ntawm 5G, nws tuaj yeem siv rau kev tsim cov khoom siv sib xws; Hauv kev tsim hluav taws xob photovoltaic tuaj yeem txhim kho kev hloov pauv kev ua haujlwm; Kev thauj mus los ntawm kev tsheb ciav hlau tuaj yeem siv nws qhov kub thiab txias ua haujlwm siab.

Product Detail

Khoom cim npe

Cov hauv qab no yog cov yam ntxwv ntawm 2inch silicon carbide wafer

1. Hardness: Mohs hardness yog hais txog 9.2.
2. Crystal qauv: hexagonal lattice qauv.
3. High thermal conductivity: lub thermal conductivity ntawm SiC yog ntau dua li ntawm silicon, uas yog conducive rau zoo tshav kub dissipation.
4. Qhov sib txawv band dav: qhov sib txawv ntawm SiC yog li ntawm 3.3eV, haum rau qhov kub thiab txias, siab zaus thiab siab zog siv.
5. Kev tawg hluav taws xob thiab hluav taws xob txav mus los: Siab tawg hluav taws xob thiab hluav taws xob txav hluav taws xob, tsim nyog rau cov khoom siv hluav taws xob zoo xws li MOSFETs thiab IGBTs.
6. Kev ruaj ntseg tshuaj thiab hluav taws xob tiv thaiv: haum rau qhov hnyav ib puag ncig xws li aerospace thiab kev tiv thaiv hauv tebchaws. Cov tshuaj tiv thaiv zoo heev, acid, alkali thiab lwm yam tshuaj hnyav.
7. High mechanical zog: zoo heev mechanical zog nyob rau hauv qhov kub thiab txias ib puag ncig.
Nws tuaj yeem siv dav hauv lub zog siab, siab zaus thiab cov khoom siv hluav taws xob kub kub, xws li ultraviolet photodetectors, photovoltaic inverters, hluav taws xob tsheb PCUs, thiab lwm yam.

2inch silicon carbide wafer muaj ntau daim ntawv thov.

1.Cov khoom siv hluav taws xob hluav taws xob: siv los tsim lub zog ua haujlwm siab MOSFET, IGBT thiab lwm yam khoom siv, dav siv hauv kev hloov hluav taws xob thiab hluav taws xob tsheb.

2.Rf cov khoom siv: Hauv cov khoom siv sib txuas lus, SiC tuaj yeem siv rau hauv cov khoom siv hluav taws xob ntau zaus thiab RF fais fab amplifiers.

3.Photoelectric li: xws li SIC-raws li leds, tshwj xeeb tshaj yog nyob rau hauv xiav thiab ultraviolet daim ntaub ntawv.

4.Sensors: Vim nws qhov kub thiab txias thiab tshuaj tsis kam, SiC substrates tuaj yeem siv los tsim cov ntsuas kub thiab lwm yam kev siv sensor.

5.Military thiab aerospace: vim nws qhov kub thiab txias tsis kam thiab cov yam ntxwv muaj zog, haum rau siv nyob rau hauv huab cua puag ncig.

Daim ntawv thov kev lag luam tseem ceeb ntawm 6H-N hom 2 "SIC substrate suav nrog lub zog tshiab tsheb, kev sib kis hluav taws xob siab thiab kev hloov pauv, cov khoom dawb, tsheb ciav hlau ceev, lub cev muaj zog, photovoltaic inverter, mem tes fais fab mov thiab lwm yam.

XKH tuaj yeem kho nrog cov thicknesses sib txawv raws li cov neeg siv khoom xav tau. Muaj qhov sib txawv roughness thiab polishing kev kho mob. Ntau hom doping (xws li nitrogen doping) tau txais kev txhawb nqa. Lub sij hawm xa tuaj yog 2-4 lub lis piam, nyob ntawm qhov kev hloov kho. Siv cov khoom ntim los tiv thaiv zoo li qub thiab tiv thaiv seismic ua npuas ncauj kom muaj kev nyab xeeb ntawm lub substrate. Ntau yam kev xaiv thauj khoom muaj, thiab cov neeg siv khoom tuaj yeem tshawb xyuas cov xwm txheej ntawm kev xa khoom hauv lub sijhawm tiag tiag los ntawm tus lej taug qab tau muab. Muab kev txhawb nqa thiab kev pab tswv yim los xyuas kom meej tias cov neeg siv khoom tuaj yeem daws teeb meem hauv kev siv.
