Zusammenfassung:Methods and structures for critical dimension or profile measurement are disclosed. The method provides a substrate having periodic openings therein. Material layers are formed in the openings, substantially planarizing a surface of the substrate. A scattering method is applied to the substrate with the material layers for critical dimension (CD) or profile measurement.
