Patent ID: 7640138

Claim:
A method of inspecting an interconnection pattern formed by depositing a metal onto a substrate having an interconnection pattern groove formed on a surface thereof, comprising: selectively measuring a thickness of a first part of a metal film above the substrate in a non-contact and non-destructive manner, the metal film being formed on the substrate and having the first part and a second part, the first part of the metal film constituted of the metal deposited upward from substantially the same surface as the surface of the substrate on which an interconnection pattern groove is formed, the second part of the metal film being constituted of the metal deposited within the interconnection pattern groove; previously preparing a relationship between a film thickness value of the first part and a filling ratio in the interconnection pattern groove; and evaluating, by an evaluator, how successfully the interconnection pattern groove is filled with the metal on the basis of a film thickness value obtained by the selective measurement and the relationship between the film thickness value of the first part and the filling ratio in the interconnection pattern groove, without measurement of a thickness of the second part of the metal film.
