WebApr 15, 2024 · The RRV is calculated from 9 point SEMI MF-81 sampling plan C resistivity measurements on each wafer. All 98 wafers are well below the 2% RRV limit set for the Advanced NTD, and only one wafer is above 1.5%. The mean RRV value for the 98 wafers is 1.08% with a standard deviation of 0.17% and the 95% quantile is 1.38%. WebFeb 15, 2024 · Monocrystalline silicon rods is got through float zone growth, and then process the monocrystalline silicon rods into silicon wafers, called float zone silicon wafers. Since the zone-melted silicon wafer is not in contact with the quartz crucible during the floating zone silicon process, the silicon material is in a suspended state.
