Abstract:
Determining a property of a layer of an integrated circuit (IC), the layer being formed over an underlayer, is implemented by performing the steps of: irradiating the IC to thereby eject electrons from the IC; collecting electrons emitted from the IC and determining the kinetic energy of the emitted electrons to thereby calculate emission intensity of electrons emitted from the layer and electrons emitted from the underlayer calculating a ratio of the emission intensity of electrons emitted from the layer and electrons emitted from the underlayer; and using the ratio to determine material composition or thickness of the layer. The steps of irradiating IC and collecting electrons may be performed using x-ray photoelectron spectroscopy (XPS) or x-ray fluorescence spectroscopy (XRF).

Claim (Index 29):
The metrology module of  claim 28 , wherein the coefficients comprise a top coefficient correlated to the width of upper surface of a feature on the top surface of the IC, a sidewall coefficient correlated to length of sidewall of the feature on the top surface of the IC, and bottom coefficient correlated to width of bottom surface of the feature on the top surface of the IC.
