Abstract
A film inspecting apparatus is used for inspecting fine roughness and particle state on a surface of a thin film. In inspecting the thin film surface, shape data of the thin film are obtained by a scanning type probe microscope. The obtained shape data are analyzed to identify individual particles, and the fine roughness and particle state on the thin film surface are inspected based on the particle data obtained by the shape data analysis. The film inspecting apparatus includes a particle analyzing device for inspecting the fine roughness and particle state on the thin film surface by using the shape data obtained by the scanning type probe microscope. The particle analyzing device includes a particle extracting device for extracting the particles on the film surface from the shape data, and a particle data calculating device for calculating the particle data based on the data extracted by the particle extracting device.
