Nettet22. mar. 2024 · LER (Line Edge Roughness) and LWR (Line Width Roughness) of the semiconductor device are an important evaluation scale of the performance of the device. Conventionally, LER and LWR is evaluated from CD-SEM (Critical Dimension Scanning Electron Microscope) images. However, CD-SEM measurement has a problem that … NettetWhen a grating is selected in the Images tree (when the Group_n label is selected), and the Line Edge Roughness button is clicked, the roughness is calculated for each individual line edge as well as the collective length of line in the full grating. By evaluating LER over the longer length of all grating edges combined, a less noisy PSD results.
