Etched profiles of SiO2 Layer

Etched-edge profile equations of SiO2 in a double layer of fast- and slow-etching SiO2 layer have been derived using Fermat's principle of least time. Etched profiles obtained from the SEM (scanning electron microscope) micrographs for experimental samples show reasonable agreement with calculated profiles.
