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.
