Qhov sib txawv ntawm Silicon Carbide Substrate Thiab Wafer

Wafer yog hais txog silicon wafer siv los ua silicon semiconductor circuits, thiab nws cov khoom raw yog silicon. High-purity polycrystalline silicon yog yaj thiab tov nrog silicon siv lead ua cov noob, thiab maj mam rub tawm mus rau cylindrical ib leeg siv lead ua silicon. Tom qab lub silicon ingot yog av, polished, thiab hlais, nws tsim ib silicon wafer, uas yog, wafer.
Tam sim no, domestic wafer ntau lawm kab yog tsuas yog 8-inch thiab 12-inch. Silicon carbide yog ib yam khoom tsis muaj zog nrog cov tshuaj formula ntawm SiC, uas yog smelted ntawm qhov kub thiab txias nyob rau hauv lub qhov cub ua hauj lwm nrog raw cov ntaub ntawv xws li quartz xuab zeb, roj av coke (los yog thee coke), ntoo chips (ntsev yuav tsum tau tsim ntsuab silicon carbide. ). Silicon carbide substrate cov ntaub ntawv yog tsuas yog siv nyob rau hauv lub hwj chim Cheebtsam nyob rau hauv ntse daim phiaj, rail transit, hluav taws xob tsheb, tshiab zog daim phiaj kev twb kev txuas, hloov cov khoom siv fais fab, muaj motors, thiab cov khoom siv hauv tsev.
