VET Energy's 8-nti silicon wafers yog siv dav hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv sib txuas thiab lwm yam. Ua ib tus thawj coj hauv kev lag luam semiconductor, peb tau cog lus los muab cov khoom zoo Si Wafer kom tau raws li qhov xav tau ntawm peb cov neeg siv khoom.
Ntxiv rau Si Wafer, VET Energy kuj muab ntau yam khoom siv semiconductor substrate, suav nrog SiC Substrate, SOI Wafer, SiN Substrate, Epi Wafer, thiab lwm yam. Wafer, muab kev txhawb zog rau kev txhim kho cov khoom siv hluav taws xob txuas ntxiv mus.
VET Energy muaj cov cuab yeej tsim khoom siab heev thiab ua tiav kev tswj hwm zoo kom ntseeg tau tias txhua lub wafer ua tau raws li cov qauv kev lag luam nruj. Peb cov khoom tsis yog tsuas yog muaj cov khoom siv hluav taws xob zoo, tab sis kuj muaj lub zog zoo txhua yam thiab thermal stability.
VET Energy muab cov neeg siv khoom nrog cov kev daws teeb meem wafer, suav nrog wafers ntawm ntau qhov sib txawv, hom thiab doping concentrations. Tsis tas li ntawd, peb kuj muab kev pabcuam kev tshaj lij thiab kev pabcuam tomqab muag los pab cov neeg siv khoom daws teebmeem ntau yam uas tau ntsib thaum lub sijhawm tsim khoom.
