抜粋

Generation rates of Si/SiO2 interface defects, namely, the oxide trapped holes and the interface states, by MeV He single ion irradiation have been investigated quantitatively. From the analysis of threshold voltage shifts induced by single ions of 2 MeV He, the number of the oxide trapped holes and the interface states induced in an n-ch MOSFET in CMOS4007 by a single ion have been estimated to be about 28 and 9, respectively. The hole trapping efficiency is almost 100% at the ion dose below 1 ions/ μm2.
