Abstract:
A method for simultaneous monitoring of the degree of cure and oxidation of an organic, spin-on dielectric material comprising the steps ofpreparing the sample by coating a thin film of a precursor material, which is free of fluorescent probe molecules onto a substrate and subjecting the precursor material to conditions to attempt to cause cure of the precursor to an organic, aromatic, polymer having a dielectric constant of less than 3.0, exposing the sample to radiation having a wavelength in the range of 200 to 500 nm, detecting a resulting emission of radiation, and comparing the emission to an emission for at least one standard for the polymer, which standard has a known degree of cure and a known degree of oxidation, thereby obtaining an estimated degree of cure and estimated degree of oxidation for the sample.
