Abstract

The characterization of sub-100 nm photolithographic patterns with nanometer scale resolution is demonstrated using Small Angle X-ray Scattering (SAXS). The transmission scattering geometry employed is capable of high throughput measurements with equivalent capabilities for future technology nodes of the semiconductor industry, organic and inorganic nano-scale devices, and 3-dimensional structures. The method is demonstrated through the characterization of a series of polymer photoresist gratings produced under typical commercial photolithographic imaging conditions. Quantities such as periodicity and line width are extracted in a model independent fashion, while additional parameters and a full line shape extraction are discussed.
