Abstract
We propose a methodology for the mathematical and quantitative characterization of the deviation of rough line/space patterns from their ideal smooth shape to identify defects related to line mass and shape. The methodology is applied in real AFM images of line/space patterns while a modelling framework is elaborated for the generation of rough line/space patterns with controlled top and sidewall roughness and size variations. We also explore the consequences of the proposed methodology in the metrology of LER and its relation to 3D patterns.
