Line edge roughness定義
Nettet2. mar. 2024 · According to the correlation between the edges of the lines, we can have line edge roughness (LER, correlated edges) or line width roughness (LWR, totally anti-correlated). The roughness types are distinguishable by the scattering out of the diffraction orders [ 13, 20] as predicted by Fourier optics using binary gratings [ 20 ]. Nettet1. jun. 2004 · The line edge roughness is usually characterized by the 3σ value where σ is defined as (1) σ= ∑ i=1 N (δW(z i)−δW) 2 N−1 1/2, where δW(z i) is the deviation …

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. Nettet中国科学院微电子研究所计算光刻研发中心版权所有 邮编：100029 单位地址：北京市朝阳区北土城西路3号 邮箱：[email protected]

A line edge roughness analysis software is developed based on the Canny edge detection algorithm with a double threshold, where threshold values are obtained by Otsu’s method. The performance of the software is demonstrated on features with a 200-nm nominal pitch generated by current-controlled, field-emission …
NettetThe nominal line/space ratio is 1:4. Line width and line edge roughness samples with programmed roughness were created by adding “tabs”, similar to optical assist features common in photoresist image design, with a pre-determined distance between centers along the line edge, given the label “roughness wavelength” in this report.
