Cov txiaj ntsig ntawm cov khoom siv sib xyaw ua ke semi-insulating SiC suav nrog:
Kev tiv taus siab: cov ntaub ntawv SiC semi-insulating muaj kev tiv taus siab, ua rau lawv muaj peev xwm thaiv cov dej ntws tam sim no thiab tsim nyog rau cov khoom siv hluav taws xob tshwj xeeb.
Kev ua haujlwm kub siab: Cov ntaub ntawv SiC muaj peev xwm ua haujlwm hauv qhov chaw kub siab, ua rau lawv tsim nyog rau kev siv hluav taws xob muaj zog thiab zaus siab.
Lub zog hluav taws xob siab: Cov ntaub ntawv SiC muaj lub zog hluav taws xob siab thiab muaj peev xwm tiv taus cov teb hluav taws xob siab yam tsis muaj kev tawg hluav taws xob.
Kev Tiv Thaiv Tshuaj Lom Zem thiab Ib puag ncig: SiC tiv taus kev xeb tshuaj lom neeg thiab tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav rau cov ntawv thov uas nyuaj.
Txo qhov poob hluav taws xob: SiC substrates tso cai rau kev hloov pauv hluav taws xob zoo dua thiab txo qhov poob hluav taws xob hauv cov khoom siv hluav taws xob piv rau cov ntaub ntawv silicon ib txwm muaj.
Zuag qhia tag nrho, cov khoom siv SiC sib xyaw ua ke semi-insulating muaj cov txiaj ntsig zoo hauv kev tsim cov khoom siv hluav taws xob ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas xav tau kev ua haujlwm kub siab, lub zog ceev ceev thiab kev hloov pauv hluav taws xob zoo.
Kev Muag Khoom & Kev Pabcuam Rau Cov Neeg Siv Khoom
Kev Yuav Khoom Siv
Lub chaw yuav khoom siv yog lub luag haujlwm sau tag nrho cov khoom siv raw uas xav tau los tsim koj cov khoom. Kev taug qab tag nrho ntawm txhua yam khoom thiab cov ntaub ntawv, suav nrog kev tshuaj xyuas tshuaj lom neeg thiab lub cev yeej ib txwm muaj.
Zoo
Thaum lub sijhawm thiab tom qab kev tsim khoom lossis kev ua haujlwm ntawm koj cov khoom, lub chaw tswj xyuas zoo koom nrog kev ua kom ntseeg tau tias txhua yam khoom siv thiab kev kam rau ua tau raws li lossis tshaj koj cov lus qhia.
Kev Pabcuam
Peb zoo siab uas peb muaj cov neeg ua haujlwm tsim khoom muag khoom uas muaj ntau tshaj 5 xyoos kev paub hauv kev lag luam semiconductor. Lawv tau kawm los teb cov lus nug txog kev siv tshuab thiab muab cov lus hais raws sijhawm rau koj cov kev xav tau.
peb nyob ntawm koj ib sab txhua lub sijhawm thaum koj muaj teeb meem, thiab daws nws hauv 10 teev.
