Line Width Roughness effects on device performance: The role of the gate width design

The role of the gate width in the effects of Line Width Roughness (LWR) on transistor performance is investigated. Two mathematical results regarding the statistical nature of LWR are presented and discussed. Exploiting the implications of these results through a 2D modeling approach, we indicate that, for fixed LWR, transistors with large gate widths seem to mitigate the degradation effects of LWR on transistor performance.
