Raws li kev siv cov khoom siv hluav taws xob silicon carbide (SiC) txuas ntxiv nce hauv cov haujlwm xws li tsheb tshiab, lub zog hluav taws xob photovoltaic, thiab cov tshuab hluav taws xob muaj zog, kev ntseeg tau tseem yog ib qho kev txhawj xeeb tseem ceeb rau kev lag luam. Los ntawm thawj zaug tsis muaj cov kev cai tshwj xeeb rau SiC hauv AEC-Q101 E specification hauv 2021, los ntawm kev qhia tom qab ntawm cov kev ntseeg siab sab hauv los ntawm cov tuam txhab ua lag luam xws li Infineon thiab ON Semiconductor, mus rau 2025 hloov tshiab ntawm AQG-324 cov qauv, kev lag luam nrhiav kev txhim kho SiC cov cuab yeej tsis muaj kev cia siab.
Thaum Lub Rau Hli 2026, JEDEC (Solid State Technology Association) tau ua ib qho kev tawm tsam los ntawm kev tshaj tawm cov ntaub ntawv kev tshaj lij JEP204, hu ua "Catalog of Stress Procedures for Silicon Carbide Devices for Power Electronic Conversion." Tsim los ntawm JC-70 Wide Bandgap Semiconductor Committee, cov ntaub ntawv no tau sau tag nrho cov kev ntsuam xyuas kev ntxhov siab rau SiC transistors thiab diodes, muab cov ntaub ntawv qhia tseeb kev ntseeg siab rau tag nrho cov kev lag luam saw.
JEP204 npog dab tsi?
JEP204 categorizes kev ntsuam xyuas kev ntxhov siab ntawm SiC cov khoom siv hluav taws xob rau hauv tsib hom loj, npog tag nrho cov spectrum ntawm chips mus rau ntim. Nws systematically summarizes lub tsis ua hauj lwm mechanisms, kev nyuaj siab tej yam kev mob (xws li, kub, av noo, hwj chim, zaus), thiab cov ntsiab lus tseem ceeb rau txhua qhov kev xeem. Tsis tas li ntawd, nws qhia txog SiC cov khoom siv, cov khoom yuav tsum tau muaj, kev soj ntsuam xyuas cov kev ntsuas tshwj xeeb, thiab xaus - ntawm - cov txheej txheem xeem.
Tam sim no peb tshuaj xyuas cov ntsiab lus xeem uas tau sau los ntawm JEP204:
