Nettet1. jun. 2004 · The line edge roughness is usually characterized by the 3 σ value where σ is defined as σ= ∑ i=1 N (δW (z i )−δW) 2 N−1 1/2, where δW ( zi) is the deviation from the average line edge δW to a best straight fit and N is the number of measurement points. It is not sufficient to measure only the 3 σ variation; a more complete ... Nettet11. des. 2002 · Line edge roughness: characterization, modeling and impact on device behavior Abstract: Simple analytical expressions are presented, which calculate the impact of line edge roughness on MOSFET parameter fluctuations. It is experimentally demonstrated that LER has no impact on 80 nm gate length transistors.
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.
