The sub-nm hillock defects have been analyzed by the Raman spectroscopy and the number of surface defects increases as the radiation dose increases and reaches a saturation value.
WebSep 2, 2024 · These hillock defects are formed during the high-temperature growth process with associated point-defect diffusion and gettering. So, this work indicates that an extended region of electronic impact can be associated with these defects, which can be well beyond the physical size of the hillock defect. WebThe number of hillock defects decreases from 118 to 65. Defect map 710 illustrates inspection result obtained from intermetal dielectric (IMD) level 4 without the anneal step. Defect map 712 illustrates inspection results obtained from the same lot but had subjected to the anneal process. The number of hillock defects decreased from 157 to 52.
