Surface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short-… WebFeb 27, 2014 · Abstract. LWR (line width roughness) is normally defined as the 3 sigma of critical dimension (CD) variation along a segment of a line. As CDs of semiconductor devices continue to be scaled down, LWR, the looming critical index, needs to be well controlled within 8% of gate line CD for advanced logic technology nodes as ITRS states.
